摘要
解放以来,我国小麦生产发展迅速。从六十年代初千斤试验田的大量涌现,发展到目前不论北方或南方,较大面积亩产千斤左右的高产试验田随处可见。在西藏、青海、新疆、云南等冷凉地区已出现亩产1,500斤以上的丰产试验田。为我国小麦生产展示了美好的前景。
Having analysed the fact of the high-yielding wheat varieties of 1,500 jin per mu in our country,we come to the conclusion that in breeding of a new wheat variety with a yield potential over 1,500 jin per mu,it must be to increase the grain weight per car of the varieties yielding 1,000 jin per mu.According to the analysis of the genetic material data,it showed that the increasing of 1,000 grain weight is rather an easier way to win a high yield of wheat than that of in-creasing the number of grains per ear,and it also seemes to be more reliable.As a high-yielding variety of 1,500 jin per mu often posseses multiple good charaeters,the increasing of 1,000 grain weight of the good variety yielding over 1,000 jin per mu will also accompany by a good character.In order to realize the above target,a lot of research work to be done in creating the germplasm of the big grain variety.
