近几年,玉米育种者选育出的优良品种层出不穷,在种子生产中会遇到有些品种的种子籽粒较小而被清选出去,因此一些籽粒较小的良种会被白白浪费,使优良种子得不到充分应用,降低利用率。本研究旨在探讨发芽率达到国标的玉米种子籽粒大小对其F1性状及产量的影响程度,以确定小籽粒种子在缺种年份能否应用及是否会造成经济损失,为农业生产提供参考。 In recent years, corn breeders have bred an endless stream of fine varieties. In the production of seeds, some varieties of seeds will encounter fewer seeds and be cleared out. Therefore, some smaller seeds will be wasted and the fine seeds Not be fully used to reduce utilization. The purpose of this study was to investigate the effect of seed germination rate on the F1 traits and yield of maize seeds with the germination rate reaching the national standard in order to determine whether the application of small seed seeds could cause economic losses in the years of lack of planting and provide a reference for agricultural production.
