| dc.description.abstract | The present study is based on molecular markers and quality analysis of F3 lines derived from two crosses. The first cross (UC 1113 + Gpc-B1 X PDW 291) was used to investigate the effect of Gpc-B1 gene by marker (Xucw 108) based identification of F3 lines carrying/lacking the gene and associating it with a set of durum wheat quality parameters. Gpc-B1 gene is originally derived from T. diococcoides. Presence of Gpc-B1 gene resulted in an average increase in grain protein content of 7.11 %. On an average F3 lines positive for Gpc-B1 gene showed lower 1000 grain weight, test weight, grain hardness and yellow pigment content. The analysis of variance also showed a significant influence of Gpc-B1 gene on grain protein content as well as 1000 grain weight, test weight, grain hardness, yellow pigment content and days to 50% flowering. Inter-trait correlation in the set of F3 lines showed negative correlation between grain protein content and 1000 grain weight and test weight (-0.45 and -0.55). The second cross (UC 1113 + Y X PDW 291) was used to investigate the effect of Y gene by marker (BF145935) based identification of F3 lines carrying/lacking the gene and associating it with a set of durum wheat quality parameters. Y gene is originally derived from Lopophyrum ponticum. Presence of Y gene resulted in an average increase in yellow pigment content of 24.03%. On an average F3 lines positive for Y gene showed lower 1000 grain weight, test weight and grain hardness. The analysis of variance also showed a significant influence of Y gene on yellow pigment content as well as 1000 grain weight, test weight, grain hardness, sedimentation value and days to 50% flowering. Inter-trait correlation in the set of F3 lines showed negative correlation between yellow pigment content and 1000 grain weight, test weight and grain hardness (-0.65, -0.48 and -0.50). Both these genes have clear positive effect on the primary traits (grain protein content and yellow pigment content) influenced by them. The two genes thus hold promise for Indian durum wheat breeding. | en_US |
