应用HSC法综合评价春大豆新品种的高产稳产性

Using High Stability Coefficient Method to Appraise Comprehensively The High Yield and Yield Stability of New Soybean Varieties

利用ＨＳＣ 法综合评价１９９８ 大豆区试３ 区新品种，综合性状优良的品系合交９３ － １５３８ 、合交９３ － １１１ 、绥９４ － ５８８６ 等。各品种高稳系数的位次与平均产量、产量稳定性系数位次不同。ＨＳＣ与Ｓ、ＣＶ、ｂｉ、Ｘ 相关系数分别为０ ．５９ ＊ 、０ ．７１ ＊ ＊ 、０ ．５ 、０ ．９１ ＊ ＊ 。可见ＨＳＣ 法是高产性与稳产性的综合反映，是综合评价大豆新品种的一种简单、易算、实用、科学的方法。

Taking advantage of HSC method the new soybean varieties (lines) were appraised comprehensively in 1998. The lines with good comprehensive characters were Hejiao 93-1583, Hejiao 93-111 and Sui 94-5886. The seating of lines tested was different between HSC and average yield and yield stability. The correlation coefficients between HSC and stand deviation, coefficient of variation, coefficient of regression and average yield were 0.59 *,0.71 * *,0.5 and 0.91 * * respectively. So, the HSC method is a simple, scientific and good method to appraise comprehensively the yield and yield stability of new soybean varieties(lines).
