(Univ Kebangsaan Malaysia, 2019) Dumlupınar, Ziya; Güngör, Hüseyin; Dokuyucu, Tevrican; Herek, Sevgi; Tekin, Ali; Akkaya, Aydın
In recent years, mapping populations have provided improvements for oat genomic researches. A two-year study was conducted in East-Mediterranean conditions using Ogle1040/TAm O-301 pure-line mapping population including 136 individuals and parents. Stem diameter (SD), plant height (PH), panicle length (PL), vegetative period (VP), grain filling period (GFP), days to maturity (DM), grain number per panicle (GNP), grain weight per panicle (GwP), thousand kernel weight (TKW) and grain yield (GY) were investigated in 2014 and 2015 cropping seasons in Kahramanmaras. All the investigated traits were significantly different for years (p<0.01) and genotypes (p<0.05 and p<0.01) except SD and GNP. Genotype x year (G x Y) interaction was significant for PL, VP, GFP, DM and GY (p<0.01). In the first year, the average GY per row was 227.6 g, whilst it was 184.5 g in the second year. In terms of GY, the parents Ogle 1040 and TAM O-301 showed lower performance (154.5 and 111.5 g/row, respectively) compared to Ogle1040/TAm O-301 (OT) population average (206 g/row). OT129 genotype had the highest GY with 360 g/row. Principal component (PC) factor analysis yielded 10 PC explaining 100% of total variance in the data and the chi-square values of the PC1 to PC9 were found significant. According to PC biplot analysis, genotypes with high GY, TKW, GNP, GWP, PL and GFP were located throughout the right quadrants whereas the genotypes with high VP, DM and SD were located throughout the left quadrants. The relationships between PH x GY, GWP x GNP and GWP x TKW were positive and significant.

(Friends Science Publ, 2019) Güngör, Hüseyin
Durum wheat (Triticum turgidum ssp. durum Desf.) is a traditional Mediterranean crop and widely produced in Turkey. This study was carried out to compare the allelic variation and agronomic characteristics of durum wheat genotypes during 2015-2016 and 2016-2017 in a randomized complete block design with four replications. A total of 14 durum wheat genotypes including twelve durum wheat cultivars (Guney Yildizi, Sari Barak, Saricanak 98, Zenit, Burgos, Saragolla, Cesare, Zuhre, Levante, Ecem, Svevo, Dumlupinar), one old variety (Kundum-1149) and a landrace (Karakilcik) were used as plant materials. Allelic variations of the 14 dumm wheat genotypes were determined using 11 DNA markers. According to the results, genotypes were found variable for all investigated traits except grain filling period (GFP), years were found different for all traits except gluten content (GC) and yellowness (B) and genotypexyear interaction (GxY) varied for plant height (PH), vegetative period (VP), days to maturity (DM), grain number per spike (GNS), test weight (TW), thousand kernel weight (TKW), grain yield (GY) and GC. The highest grain yield was obtained from Cesare cultivar over two year data with 5568 kg ha(-1) and followed by Burgos and Svevo cultivars with 5080 kg ha(-1) and 5027 kg ha(-1), respectively. Protein ratio (PR) of the genotypes ranged between 10% to 14.8% and Cesare and Karalulcik had the highest PR. According to the dendrogram, Burgos and Karalulcik genotypes were found similar in terms of the alleles investigated in the study with 86%. San Barak and Dumlupmar genotypes were found the most diverse compared to the other genotypes. Eleven allele specific DNA markers interrogated in 20 loci and the allele number per marker was found as 1.8. The average polymorphism information content (PIC) was identified as 72.5%. Cesare cultivar produced bands for eight allele specific markers and Zenit cultivar was the only cultivar that produced allele for Xgwm18 marker. The findings of this study may shed light to breeding programs with field and laboratory performance of these genotypes. (C) 2019 Friends Science Publishers

COMPARISON OF MEAN YIELD COMPONENTS AND FIBER QUALITY PARAMETERS OF ADVANCED BULK GENERATIONS IN F-2, F-3 AND F-4 INTERSPECIFIC AND INTRASPECIFIC COTTON POPULATIONS
(Soc Field Crop Sci, 2017) Başal, Hüseyin; Demirok, Burcu; Karahan, Tunay; İlker, Emre; Güngör, Hüseyin
The performance of interspecific and intraspecific cotton hybrid populations were compared to investigate the correlation among the F-2, F-3 and F-4 bulk generations in terms of yield, lint percentage, and fiber quality from 2009 to 2011. In addition, the effect of combining abilities on hybrid performance were investigated at further generations. For this purpose, nine interspecific and six intraspecific hybrids with eight parents were evaluated under the west part of Turkey (Aegean region) environmental conditions. With the generation progresses, the highest drops in fiber length and fiber strength were detected in interspecific due to the inbreeding depression and genetic breakdown in advanced populations. Based on 15 tested hybrids, the observed mean yield and fiber quality in the F-2 do not adequately predict the performance of hybrids in the F-4 generation. Thus, selection of individual plants should be delayed until the F-4 generation especially for interspecific hybrids, but individual plants would be selected at early generation in intraspecific hybrid populations. In the study it was found that a higher general combining ability (GCA) does not necessarily confer a higher specific combining ability (SCA) and that the GCA and SCA were independent of one another, and that in F-4 high yielded hybrid population was obtained from cross which at least one parent of hybrid has maximum positive GCA effects. These results indicated that instead of using only one criteria, the F-2 performance for intraspecific hybrids and the F-3 performance for interspecific hybrids, low heterosis and inbreeding depression, combining ability of parents could be used together to determine the most promising hybrid populations to be used as a source for further selection.

This research was carried out during the 2016-2017 and 2017-2018 growing seasons at Edirne, Kırklareli, and Tekirdağ locations with the aim of determining some agricultural and quality traits of nine registered oat cultivars. The experiments were arranged in a randomized complete block design with four replications. According to the results of the examined traits, plant height ranged from 101.5 to 132.4 cm, vegetative period from 125.1 to 138.9 days, thousand kernel weight from 26.6 to 40.0 g, test weight from 46.2 to 53.2 kg hl-1, protein content from 12.5% to 15.1%, and grain yield from 4011 to 5321 kg ha-1. According to the biplot analysis, PC1 and PC2 (accounting for 69.3% and 18.3% of the total variation, respectively) constituted 87.6% of the total variation. The angle value between the vectors of grain yield and protein content, thousand kernel weight, and test weight was narrow, indicating a high positive relationship between these traits, whereas the angle between the vectors of grain yield and plant height and vegetative period was wide, indicating a negative relationship between these traits. According to the correlation analysis, grain yield had a positive and significant relationship with test weight (r=0.594**), protein content (r=0.431**), and thousand kernel weight (r=0.350**), and a negative and significant relationship with a vegetative period (r=-0.360**) and plant height (r=-0.047**). According to the biplot analysis, cultivars Kahraman, Kırklar, Kehlibar and Somun Yıldızı were found outstanding genotypes in terms of grain yield.

(Univ Namik Kemal, 2017) Güngör, Hüseyin; Dokuyucu, Tevrican; Dumlupınar, Ziya; Akkaya, Aydın
Grain yield is a quantitative trait that a number of characteristics has direct or indirect effects. This research was carried out in 2008-09 growing season with 22 landraces and 3 commercial oat (Avena spp.) cultivars under Kahramanmaras ecological conditions. The research was arranged in a randomized complete block design with 3 replications. In the research, the traits such as stem diameter(SD), flag leaf length (FLL), flag leaf width (FLW), plant height (PH), panicle length (PL), grain filling period (GFP), vegetative period (VP), days to maturity (DM), biomass (B), grain number per panicle (GNP), grain weight per panicle (GWP), thousand kernel weight (TKW) and grain yield (GY) were investigated; the direct and indirect effects of those traits on grain yield were evaluated using Path and correlation analysis. According to Path analysis, GFP (47.74%), VP (39.41%), B (31.15%), GNP (29.80%) and TKW (24.78%) had the highest direct effect on grain yield. Based on correlation analysis there was a positive and significant relationship between grain yield and stem diameter (r = 0.480**), flag leaf length (r = 0.230*), flag leaf width (r = 0.241*), grain filling period (r = 0.224*), days to maturity (r = 0.339**) and biomass (r = 0.313**) while a negative and significant correlation found with plant height (r = -0.315**). In the study, Path analysis and correlation coefficients used to determine direct and indirect effects of some agronomic traits on grain yield showed that GFP, VP, B, GNP and GWP might be used as a selection criteria for grain yield successfully.

Stability and the preferred response of genotypes over various environments are essential for plant breeders. Six registered cultivars (Truva, Alperbey, Collegial, Karma 2000, Melez 2001 and Tatlicak 97) and two advanced lines (TRTrp16 and TR-Avk16) were studied across six environments (E) during two growing seasons in 2016-2017 and 20172018 at three locations (Kirklareli, Tekirdag and Edirne) in Turkey. Genotype (G), genotype x year (G x Y), genotype x location (G x L) and genotype x year x location (G x Y x L) interactions were found significant for all investigated traits. Grain yield of the genotypes ranged from 5539 to 6800 kg ha(-1) and cultivar Collegial had the highest grain yield (6800 kg ha(-1)), while cultivar Melez 2001 had the lowest (5539 kg ha(-1)). In terms of years, grain yield was higher in 2017 (6466 kg ha(-1)) and lower in 2018 (6016 kg ha(-1)). Among the test environments, Edirne was the highest for grain yield (7872 kg ha(-1)) followed by Kirklareli (5638 kg ha(-1)) while Tekirdag was the lowest (5214 kg ha(-1)). Tekirdag 2018 was found as the most favourable environment in terms of grain yield. Results revealed that Collegial was the most superior genotype across environments and cultivar Alperbey was the most stable genotype. This study indicates that cultivar improvement efforts should be put on to develop triticale genotypes for the specific environments rather than a broad adaptation.
EVALUATION OF WHEAT GENOTYPES: GENOTYPE x ENVIRONMENT INTERACTION AND GGE BIPLOT ANALYSIS
(Soc Field Crop Sci, 2022) Güngör, Hüseyin; Çakır, Mehmet Fatih; Dumlupınar, Ziya
This research was carried out to evaluate the grain yield, yield traits and some quality traits of 18 bread wheat genotypes at seven environments in Thrace region using principal component analysis and genotype (G) + genotype x environment interaction biplot analysis to determine the genotypes with high yield and desired quality characteristics during the 2016-2017 and 2017-2018 growing seasons. The experiments were arranged in a randomized complete block design with four replications. Genotype, environment and genotype x environment interactions (GE) were found statistically significant at p <= 0.01 level for all investigated traits. Mean values of the cultivars varied from 4841-6807 kg ha(-1) for grain yield, 118.6-131.6 days for heading date, 80.4-104.7 cm for plant height, 7.7-10.4 cm for spike length, 16.4-20.3 for number of spikelets per spike, 34.2-59.6 number of grains per spike, 1.49-2.41 g grain weight per spike, 72.0-77.8 kg hl(-1) for test weight and 36.6-45.3 g for thousand kernel weight. Principal component biplot analyses explained the relationships between the investigated traits and genotypes at a ratio of 60.9% According to the principal component (PC) biplot analysis, it was observed that there was a positive and significant relationship between grain yield and test weight, a negative relationship with grain yield and spike length and grain weight per spike. GGE biplot analysis explained 82.65% of the relationship of G + GE for grain yield. According to the GGE biplot analysis, two mega environments were determined and Lucilla and Glosa genotypes took place in the biggest mega environment consisted of four environments as superior genotypes.
