摘要: 本文用估算品种丰、稳指数的方法、综合评定汕优63,D优63,D优10号,协优63和Ⅱ-32A×明恢63的丰产性和稳产性,分析结果表明:(1)五个品种的离回归方差(di2)不显著,稳产性较好,(2)汕优63,D优63,D优10号,协优63和Ⅱ-32A×明恢63的丰稳指数分别为:101.337,97.978,103.198,96.087,99.341;以汕优63为对照,D优10号,D优63,协优63Ⅱ-32AX明恢63的丰稳指数优势率分别为:2.43%,-3.31%,-5.18%,-1.97%,(3)五个品种的丰,稳产性"权"比分别为:丰产性"权"比为67.71,稳产性"权"比为32.29。并以汕优63为对照,对其余四个品种作了优势区间分析。

Abstract: The productivity and stability of five rice hybrid varieties (SHANYOU 63, D-You63, D-you 10, XIEyou 63, Ⅱ-32A×MINGHUL63) were evaluated by estimating their indices of productivity and stability, The results are shown as follows (1) Sdi2 of the five rice varieties was not singnifisent, suggesting a good stability, (2) The indices of productivity and stability for the five rice varieties (SHANY you 63, D-you63, D-you 10 XIETyou63, Ⅱ-32A×MINhu63) were 101.337, 97.978, 103.798, 96.087, 99.341 respectively, and compaed to the check SHANyou 63, the heterosis rates of the indices of productivity and stability are D-you 10(2.43%) D-you63(-3.31%), XIEyou 63(-5.18%), Ⅱ-32A×MINGHUI63(-1.97%), (3) The Weights of productiveity and stability of the five rice varieties are 67.71 and 32.29 respectively;(4) The This study analyzed The four rice varieties for heterosis intervals too, compared to The check SHAN Y you63.
