运用灰色系统理论和关联度分析法 ,对通辽地区 2 5个蓖麻杂交F1代 12个单株产量构成因素进行关联分析 .结果表明 ,蓖麻杂交种产量构成各因素灰色关联度大小依次为单株粒数 >一级分枝粒重 >一级分枝蒴果数 >门桩穗长 >生育期 >百粒重 >主茎穗长 >株高 >一级分枝果穗数 >主茎粒重 >主茎蒴果数 >主茎穗位 .与单株产量密切相关的性状为单株粒数、一级分枝粒重、一级分枝蒴果数、门桩穗长和生育期
The gray system theory and correlation analysis method were used to analyze the yield components of 12 F1 progenies from 25 hybrids of castor in Tongliao.The results showed that the gray relational degree of output of castor hybrid was single Number of grains> Number of first-order branches> Number of first-order branches> Span length of gate> Growth period> One hundred kernel weight> Spike length of main stem> Plant height> Number of primary branches> Number of main stems> The main stem capsule number> main stem ear position.The traits closely related to the yield per plant were single grain number, first-grafted grain weight, first-graded boll number, gate pile spike length and growth period
