摘要
根据糯玉米区域试验资料 ,对影响籽粒产量的株型、产量性状及籽粒营养成分进行了研究。结果表明 ,紧凑型杂交种的籽粒产量及大部分产量性状高于平展型杂交种 ;穗长、穗粗和千粒重是影响籽粒产量的主导因素 ;不同杂交种之间在籽粒营养成分及果皮厚度上存在着明显差异。因此认为 ,株型紧凑、营养成分含量高及果皮薄的大穗大粒型杂交种是糯玉米育种的主要目标。
The research was carried out on the effects of plant-type and yield characteristics on their grain yield and grain nutrients, based on regional test materials of glutinous maize The results showed that grain yield and most of yield characteristics of compact-type hybrid are higher than that of flat-type hybrid The most three important factors are spike length and spike diameter and 1000 grains weight for the grain yield There are very obvious differences of grain nutrients and peel thickness between hybrids Compact-type, high grain nutrients,thin grain peel, and large spike and grain weight can be regarded as selecting main aims of glutinous maize hybrids
