Abstract

The impact of the GpcB1/Yr36 gene on agronomic attributes, grain quality parameters, and stripe rust resistance was studied in the background of the popular Indian wheat cultivar PBW550. Introgression lines SABW159 showed 21.01% enhancement in protein with no yield penalty and stripe rust-resistant reaction (10s). Similarly, SABW141 registered a 14.19% increase in protein content along with a 6.17 % yield advantage over PBW550 and the terminal disease reaction of 10S. The corresponding disease score for PBW550 was 80S. Similar trends for improvement across all three traits, viz. grain yield, GPC, and stripe rust resistance, were observed for several introgression lines, and no single yield component showed a reduction on account of enhanced protein.
