果穗长是玉米产量构成的重要因素。在一定的栽培条件下玉米自交系及其杂交种的产量在很大程度上取决于果穗的线性数量,首先是果穗的长度。因此,育种家在其研究中经常注意果穗长这个性状。掌握和利用不同栽培条件下
Ear length is an important factor in the production of corn. The yield of maize inbred lines and their hybrids under certain cultivation conditions depends very much on the linear number of ears, above all on the length of the ears. Therefore, breeders often pay attention to the ear length in this study. Master and utilize different cultivation conditions
