在育种和良种繁育工作中,收获前需要在田间分析和淘汰大量植株。因此,苏联研究藉助间接方法,即脱粒前测定高粱穗粒重的方法,对试材进行评价,经试验判明,高粱品种、杂交种及品系的穗粒重的遗传差异,均取决于生态条件。因此,随条件不同而变化的穗重,影响到籽粒重量的百分比。试验共用500穗高粱。
In breeding and breeding work, a large number of plants need to be analyzed and eliminated in the field before harvesting. Therefore, the Soviet Union studies using the indirect method, that is, the determination of sorghum spike weight before threshing method to evaluate the test material, the experiment found that sorghum varieties, hybrids and strains of grain weight differences are based on ecological conditions. Therefore, the panicle weight, which varies with different conditions, affects the percentage of kernel weight. The trial shared 500 spike sorghum.
