小麦的青秕,是造成小麦产量不稳的原因之一,它是由多种因素引起的生育后期植株早衰,灌浆不好造成的。但是不同品种的抗青秕能力有明显的差异,因此,可以肯定小麦抗青秕力的强弱与其内在的遗传基因有关。在选育小麦新品种中,对抗青秕性状的选择很有必要。为了在外在环境条件适于小麦落黄情况下,能够比较正确地选择育种材料或后代的抗青秕性能,对其生态表现与抗青秕特性的关系,有必要进行研究。为此,于1979—1981年,对527份材料的上述关系进行了测定。
Barley from wheat is one of the reasons for the unstable yield of wheat. It is caused by a variety of factors, such as premature aging and poor grouting in the later growth period. However, there are obvious differences in the ability of different varieties of barley. Therefore, it is certain that the strength of resistance to barley in wheat is related to its intrinsic genetics. In the selection of new varieties of wheat, the choice of resistance to barley traits is necessary. It is necessary to study the relationship between the ecological performance and resistance to barley in order to select the anti-baring performance of breeding materials or offspring more correctly when the external environmental conditions are suitable for the yellowing of wheat. To this end, in 1979-1981, the above relationship of 527 materials was determined.
