The panicles of 16 Turkish oat (Avena sativa L.) genotypes were obtained from three locations; Kahramanmaras, Konya and Cumra in Turkey in 2002-2003 cropping year. The panicles of each variety were divided into three spikelet groups as basal spikelet (BS), central spikelet (CS) and apical spikelet (AS). The oat groats belonging to spikelet groups were pooled to determine macronutrient and micronutrient concentrations. The results indicate that grain number (GNP) and grain weight per panicle (GWP) were significant for locations (L), genotypes (G) and spikelet groups (SG). Genotypes were significantly different for Ca, Mg and K concentrations. Locations had significant effect on Ca and Mg concentrations while there were not any significantly differences for spike...

In this study, 6 six stability measures consisting of 4 parametric and 2 nonparametric were used to evaluate the genotype by environment interaction (GEI) in 20 durum wheat genotypes. The genotypes were evaluated for grain yield at fourteen environments in the Central Anatolian Region of Turkey for two years. The experimental layout was a randomized complete block design with three replications. Genotypes, environments main effects and GEI were significant at P < 0.01. Both parametric (bi, S 2 di, Ri , Pi) and nonparametric (Si , Si ) univariate stability statistics were used to determine stability of the durum wheat genotypes. Genotypes 20, 13 and 12 were most stables based on genotypes according to six stability measures. The level of associations among the stability measures was assessed using Spearman's ...

Stability analysis [9] were to performed on results for grain yield of 5 oat cultivars (Chekota, Yesilkoy-1779, Yesilkoy-330, Faikbey-2004, Seydisehir-2004) from 24 trials (6 irrigated, 18 rain fed ) was conducted over 6 years in the Central Anatolian Region, Turkey. There was considerable variation in grain yield within and across environments. Year by location and location variability were dominant sources of interactions. The cultivar, “Seydisehir-2004” with respective regression coefficient value of 1.03, the smallest deviations from regressions (S2di) value and the highest grain yield could be considered the most widely adapted cultivar. The other test cultivars were sensitive to production-limiting factors, their wider adaptability, stability and general performance to the fluctuating growing...

The objectives were to assess genotype-environment interactions (GEI), determine stable genotypes, and compare mean grain yield with the parametric stability parameters. To quantify yield stability, nine stability statistics were calculated (bi, S2di, Ri2, W i2, σi2, S2i, αi and λi). Yilmaz-98, Cakmak-79, Kiziltan-91, Selcuklu-97 and C-1252 were more stable cultivars, which had 9, 8, 6, 6, 6 out of all 9 stability statistics used, respectively. Especially, among these cultivars, Yilmaz-98 and Cakmak-79 were the most stable cultivars. Furthermore, three-dimensional plots of mean response versus each stability statistic were shown to visually evaluate the yield potential and stability estimates ...

This research aims to evaluate 9 macro and micronutrient contents (Fe, Zn, B, K, Mn, Cu, Mg, Ca, Mo) of 37 bread wheat pure lines derived from landraces of West Anatolia (Eskişehir and Kütahya) and Thrace (Edirne and Kırklareli) regions and compare with 11 bread wheat cultivars by using GGE Biplot. Field trials are conducted by incomplete block design with two replications in 2011-2012 growing season in Dardanos Agricultural Facility of Çanakkale Onsekiz Mart University. According to the biplot graphics, iron and zinc contents of genotypes were involved into the same section when boron and molibden contents were also highly correlated. Pure line L4 (TR57999/5) were the most prominent genotype for iron and zinc contents when L36 (TR38316/2) were superior by both boron and molibden contents. Copper contents of grains were found negatively correlated with iron and zinc contents. Res...
