【摘要】 采用灰色关联度分析方法 ,对引自法国的 12个品种进行分析比较。结果表明 ,在法国蓖麻产量构成因素的几个因子中 ,其贡献率依次为单株蒴果数 >单株有效穗 >穗长 >主穗蒴果数 >百粒重 >株高 >全生育期 >每公顷株数 ,结果与生产中的实际情况基本一致。说明 ,在对法国蓖麻的引育种、生产中 ,应选择单株蒴果数、单株有效穗多的品种更多还原

【Abstract】 Analyaed the yield in twelve France castor with the method of grey correlation analysis.The result showed that in yield components,the order of contribution rate was grains per spike,effective spikes per plant,spike effective length,the number of main spike grains,100-seed weight,plant height,growth period,plant per ha,the number of burls in stalk,the result is close to product This indicated that grains per spike and effective spikes per plant were the main factors to affect the yield in breeding and producing France castor更多还原
