高蛋白大豆品种产量及子粒主要品质性状稳定性的研究

本文试用俞世蓉提出的稳定性参数分析了通化所选育的９份高蛋白大豆品种产量及子粒主要品质性状的稳定性，结果表明，通农９号、通农１０、通农１１高蛋白大豆品种产量高、蛋白质含量高、子粒外观品质好且稳定性好；并指出高蛋白大豆品种蛋白质含量高的、完全粒率高的、褐斑粒率低的、虫食粒率低的品质性状稳定性好，化学品质比子粒外观品质稳定；同时分析了蛋白质含量的稳定性与部分农艺性状的相互关系及高蛋白大豆各品质性状的变异大小与开花至成熟阶段气象因子之间的关系。

STUDY ON THE STABILITY OF THE YIELD AND THE MAIN SEED QUALITY CHARACTERS IN HIGH PROTEIN SOYBEAN CULTIVAR

Based on the method of Yu strong's stable parameters analyses .we analysed nine high protein soybean cultivars,both on their stability of the yield and the main seed quality characters. It was found that the high protein soybean cultivars Tong Non 9,Tong Non 10 and Tong Non 11 are high yield,high protein, better seed appearance quality and stability. It was also faund that if a cultivar contained higher protein,the rate of full seeds was higher,and the rate of seed coat mottling and the percentage of damaged seeds were lower, then the quality characters were more stable. The chemical component was more stable than seed appearance quality. Meanwhile,we analysed the relationship between stability of the protein and some plant characters,and the relationship between variation of the protein and the climatic factors from flowering to ripening.
