摘    要:为改造温光敏两系小麦C49S的弱点,转育了新的抗条锈温光敏两系小麦MTS-1、MTS-2.对MTS-1、MTS-2的利用价值进行了评价,研究了MTS-1、MTS-2的育性稳定性,抗性和杂种一代优势表现,结果表明:MTS-1、MTS-2比C49S具有更长的不育期,不育特性更稳定,更适合川西北生态条件,MTS-1、MTS-2免疫条锈且遗传力强,杂种一代优势明显,杂种优势主要表现在穗粒数和千粒重上.

关 键 词:小麦  温光敏不育系  条锈病  杂种优势

Abstract:In order to improve thermo-photo-sensitive male sterile wheat C49S,new stripe rust resistant thermo-photo-sensitive wheat MTS-1 and MTS-2 were bred. Fertility stability, stripe rust resistant ability and heterosis were studied to evaluation MTS-1 and MTS-2. The results were as follow: MTS-1 and MTS-2 had longer sterile phase, more sterile stability than C49S and more adapted to North-West of Sichuan. MTS-1 and MTS-2 immune to stripe rust, high heritability of rust resistance and obvious heterosis which mainly consist of greatly grain per spike and 1000-grain weight.
Keywords:wheat  thermo-photo-sensitive  strip rust resistance  heterosis
