Study on the Correlation of Yield Traits of Three Hybrid Rice Varieties Direct Sowing Culture after Rapeseed Harvesting
摘要
Abstract
Objective]Correlation of three hybrid rice varieties (F You 498,Chuanyou 6203,Jingyou 127)yield traits after rapeseed direct so-wing culture was studied.[ Method] After rapeseed direct sowing culture in demonstration field, yield traits were studied by multipoint sam-pling, then the correlation analysis, regression analysis and path analysis were carried out.[Result]The results showed that the yield of F You 498 with filled grains had very significant positive correlation.The yield of Chuanyou 6203 and Jingyou 127 had very significant positive corre-lation with effective panicles.Path analysis indicated the order of contribution size for yield was panicle weight, grains per panicle, effective panicles number, seed-setting rate, 1 000-grain weight, filled grains per panicle(F You 498);effective panicles number, 1 000-grain weight, filled grains per panicle, grains per panicle, seed-setting rate, panicle weight(Chuanyou 6203); panicle weight, effective panicles number, seed-setting rate, grains per panicle, 1 000-grain weight, filled grains per panicle(Jingyou 127).[Conclusion] In actual production, if we want to obtain high yield,we should make the yield traits coordination.关键词
