油菜产量与主要性状的灰色关联度分析
Gray relational grade analysis between the rapeseed yield and related traits
摘要
Abstract
[Objective]The present study was conducted to analyze the gray relational grade between the rapeseed yield and its relative traits of rape to provide reference resources for selecting quantitative trails in rape breeding. [Method]Based on the theory of gray relational system, the gray relational grade analysis was made between plant yield and 9 relative agronomic traits in 11 rapeseed varieties. [Result]The results showed that the gray relational grade between the yield and its related traits was observed as follows:growth period 0.6253, plant-height 0.6343, branch position 0.6421, 1" effective branch number 0.6458, length of primary inflorescences 0.5911, length of effective siliquaes in primary inflorescence 0.5775, total effective siliquaes per plant 0.5917, grains per siliquae 0.5983, weight of 1000-grain 0.6762. The relational sequence recorded as weight of 1000-grain>l" effective branch number>branch position>plant height>growth period>grains per siliquae>total effective siliquaes per plant>length of primary inflorescences>lenglh of effective siliquaes in primary inflorescences. [Conclusion]In Guangxi,we should strengthen to breed rapeseed varities in 1000-grain weight, and 1* effective branch number must be taken into account on priority basis in rape breeding.关键词
