将春小麦与小麦—中间偃麦草二体异附加系Z4杂交,F0代幼胚培养、回交,得到0P1341-1等4份对条锈病免疫、高抗的株(穗)系;分析了株高等农艺性状,各性状的遗传变异系数变幅较大,在8.04%～149.59%,变异系数最大的是单株穗数,其次是千粒重,主要产量性状的遗传变异效应有利于丰产性状的选定。1343-1的综合品质性状最好,总体上籽粒粗蛋白含量呈超亲遗传效应,而湿面筋含量和沉淀值的遗传呈双亲均值和负向遗传效应。
The spring wheat and wheat - Thinopyrum intermedium alien addition lines Z4 hybrid F0 on behalf of the immature embryo culture, backcrossed, 0P1341-1 and other four were stripe rust resistance, high resistance strain (spike) lines; analysis of plant height The agronomic traits showed that the genetic variation coefficient of each trait ranged from 8.04% to 149.59%. The coefficient of variation was the number of panicle per panicle, followed by the 1000-grain weight. The genetic variation effect of main yield traits was in favor of the selection of high yield traits. The 1343-1 had the best comprehensive quality traits. On the whole, the crude protein content of the grain showed the transgender genetic effect, while that of the wet gluten content and the sedimentation value showed the parents’ mean and the negative genetic effect.
