Relationship between Branching Height lndex and Plant Traits,Yield and Quality in Brassica napus
摘要
Abstract
In order to study the relationship between branch height index and plant characters,yield and quality in Brassica napus,based on the summary report of the national regional trial of new winter rape varieties in 10 years,the correlations between branch height index and erucic acid,glucosinolates,oil content,plant height,branch height,number of effective branches,length of main inflorescence,effective angles of main inflorescence,effective angles per plant,grains per horn,1 000-grain quality,yield per plant and yield were analyzed.The results showed that branch height index was significantly negatively correlated with glucosinolate,oil content,effective branch number,main inflorescence length,effective horn num-ber per plant,grain number per horn,1 000-grain mass,yield per plant and yield.While branch height index decreased,rapeseed population oil content,effective branch number,effective horn number per plant and seeds per horn,length of main inflorescence 1 000-grain quality,yield and yield per plant increased.Stepwise regression analysis showed that oil content,branch height index,number of effective branches,effective angles of main inflorescence,effective angles per plant,grains per horn and yield per plant had significant effects on yield.The analysis results can provide reference for screening ideal plant type index and evaluation of lodging resistance in rapeseed breeding.关键词
