EVALUATION OF YIELD AND SOME QUALITY CHARACTERS OF WINTER BARLEY (Hordeum vulgare L.) GENOTYPES USING BIPLOT ANALYSIS

According to biplot analysis that based on the visual correlation between traits, HLT, SV, GY and STR were involved in the same group, while TKW and PC were involved individually in separate groups genotypes located in corner of the polygon, G11 and G21 had highest values or desirable traits for protein content, G8 was the best for TKW while G7, Kalaycı-97 and Sladoran were the best for HLT and SV. The Northern part of southern region's climate is sufficiently humid (annual precipitation rate 500 mm) with mild-hard winter weather which enable winter barley to perform well. Because the interaction between environmental stress and barley genotypes has not been sufficiently investigated (Ceccarelli et al. 2010; Alemayehu et al., 2014;), this target should be involved in breeding strategies. (2013) reported that some barley varieties require certain times expose to cold temperatures to initiate flowering, while others initiate flowering without any obligation for vernalization. [...]learning more about genetic variation of winter and spring types in barley breeding genotypes is useful for developing and adaptation new varieties for worked environments. (2007); Sirat and Sezer (2017); in these, higher yields can be obtained in a warmer climate only by means of better adapted genotypes. [...]Akıncı and Yildirim (2009), who studied barley accessions from South East region of Turkey, reported that the decreasing of grain yield at high rainfall environment depend on lodging.
