红花品种稳定性参数的估计

Estimation of Stability Parameters for Safflower Varieties

本文根据１９９０～１９９２年，在巴盟临河红花生产基地进行的试验结果资料，采用回归系数和离回归方差２个参数对品种的稳定性进行了分析。结果表明：各参试红花品种的产量随栽培环境不同有较大的变化，但参试材料中，无刺红和１－７７－１红花品种，在各给定环境条件下，产量高而稳定，是比较理想的品种。

ased on the date of regional test in Bayannaoer League of Inner Milngo-lia during 1990～1992,the varietal stability of safflowers was measured using the regres-sion coefficient and the squared deviation from regression.The results showed that theseed gield had greatest variation in different cultivated environments, Among the entriestested,varieties” WuCiHong”and”1-77-1”had higher gields and better stabilities.They were considened ideal varieties.
