对玉米籽粒产量与穗粒数、干粒重之间的关系进行了研究。结果表明 ,穗粒数对籽粒产量的影响更大 ,育种上可把穗粒数作为重要的选择指标 ;并探讨了多粒型玉米品种的选育途径。
The relationship between the grain yield of maize and the number of grains per spike and dry weight was studied. The results showed that the number of grains per spike had a greater impact on the grain yield, and grain number per spike as an important selection index in breeding. The breeding ways of multi-grain corn varieties were also discussed.
