Abstract

Sixty-seven cultivars and advanced breeding lines from three major Indian wheat-producing zones were used to investigate the presence of 1RS.1BL translocation and high molecular weight glutenin subunits (HMW-GS), and to determine their effect on bread loaf volume and yield. The frequency of 1RS.1BL translocation was detected in 50.7% of the genotypes. Three, five and two allelic variations were observed at Glu-A1, Glu-B1, Glu-D1 , respectively. The genotypes with 1RS.1BL translocation were significantly high in grain yield and bread loaf volume than genotypes without 1RS.1BL translocation. The majority of genotypes (76.4%) possessing 1RS.1BL translocation had HMW-GS 5+10. It was concluded that the deleterious effect of rye translocation can be compensated by desirable HMW-GS at Glu-D1 locus.
