豫南甘蓝型油菜新品种产量及农艺性状的综合评价
Comprehensive Evaluation of Yield and Agronomic Traits of New Varieties of Brassica napus in Southern Henan
摘要
Abstract
In order to explore the characteristics of new rapeseed(Brassica napus L.)varieties in southern Henan and promote the effi-cient utilization and promotion of excellent rapeseed varieties,9 rapeseed varieties introduced into Xinyang were used as experimental materials.Variation analysis,correlation analysis,grey correlation analysis,DTOPSIS method and grey correlation method were used to comprehensively analyze 11 traits of these 9 varieties.The results showed that the coefficient of variation of the main traits of the test-ed varieties ranged from 0.46％to 49.89％.The yield per plant was significantly positively correlated with the number of effective siliques per plant,significantly negatively correlated with the division position,and extremely significantly negatively correlated with the growth period.The yield was significantly negatively correlated with the growth period and extremely significantly negatively correlated with the incidence rate and disease index of sclerotinia sclerotiorum.The yield per plant,effective number of siliques per plant,number of effective branches per plant and thousand-grain weight had high grey correlation with yield.The ranking of DTOPSIS method,grey correlation method and yield were similar,showing that Zhongyouza 501,Qinyou 1618,Qinyou 5903 and Xinyouza 1134 had good comprehensive characteristics.In summary,Zhongyouza 501,Qinyou 1618,Qinyou 5903 and Xinyouza 1134 are suitable for promotion and cultivation in Southern Henan region.关键词
