经返回式卫星搭载纯系小麦龙94-4083的风干种子,从第6代(SP6)中选育出了高产优质抗病性强的新品系龙辐02-0958。该品系的主要农艺性状较其亲本有不同程度的改善,在产量鉴定中较对照品种增产18.5%~22.5%,且差异极显著;较原亲本增产6.4%。在品质性状上,龙辐02-0958面粉的沉降值、面团的最大抗延阻力和面积分别较原亲本增加5.4ml、175E.U和34cm2,达到了优质强筋麦的标准。同时,龙辐02-0958的抗病性较其亲本也有不同程度的提高。
The dried sown seeds of Pure Wheat 94-4083 were picked up by the return satellites, and a new strain Longfu 02-0958 with high yield, high quality and disease resistance was selected from the sixth generation (SP6). The main agronomic traits of the strain had different degrees of improvement compared with their parents. The yield was increased by 18.5% -22.5% compared with the control varieties, and the difference was extremely significant; the yield was 6.4% higher than the original parent. On the quality traits, the settlement value of Longfu 02-0958 flour, the maximum resistance of the dough and the area of resistance increase 5.4ml, 175E.U and 34cm2 respectively compared with the original parent, reaching the standard of high quality gluten. At the same time, the disease resistance of Longyou 02-0958 is also improved to some extent compared with its parents.
