Rust resistant and high yielding durum wheat genotype: Gujarat Wheat 1353 (GW 1353)

Abstract

Wheat crop is severely affected by rust disease and cause heavy yield losses. An attempt was made to develop a rust resistance high yielding durum wheat genotype at Agricultural Research Station, Anand Agricultural University, Dhandhuka. Gujarat Wheat 1353 was developed using cross combination of GW 1205 and GW 1242. The developed genotype was tested against two local cultivated varieties Gujarat Wheat 1 and Gujarat Anand Durum Wheat 3 and two national checks HI 8627 and UAS 466. GW 1353 showed 4.65 % and 2.46 % increase in yield over checks GW 1 and GADW 3, respectively under rainfed condition. It showed 1.75 % increase in yield over check GW 1 under limited irrigation. During 2018-19, it showed 25.47 %, 14.12 %, 49.27 % and 67.57 % increase in yield over checks GW 1, GADW 3, HI 8627 and UAS 466, respectively. It revealed higher test weight (59.47 g) as against checks GW 1 (55.50 g) and GADW 3 (58.67 g). GW 1353 showed immune response for three years against black rust and five years against brown rust. It reported resistant reaction against eight stem rust and nine leaf rust pathotypes. Thus, this genotype may be useful in pre-breeding programmes.
