用不同分析方法评价家蚕品种锦·绣×潇·湘的丰产性和稳产性及丝质性状
|
摘要
对新选育品种进行全面而合理的评判是家蚕品种选育工作的一个重要环节。根据2015—2017年家蚕品种国家审定多点鉴定成绩的年度汇总数据,利用非参数统计法、高稳系数法以及稳定性参数法等分析方法,分别对农村生产鉴定成绩中的盒种产茧量、健蛹率与实验室鉴定成绩中的茧丝长、解舒率与洁净等反映家蚕品种高产稳产、丝质性状的关键性指标进行水平比较和稳定性分析,其结果与平均数、标准差、变异系数等常用方法的分析结果趋向相一致。家蚕品种锦·绣×潇·湘的盒种产茧量比对照品种秋丰×白玉高12.07%,表现出了产茧量高、稳产性强、丝质优的特点,具有广阔的推广应用前景。
A comprehensive and rational evaluation of new silkworm varieties is an important step in breeding of silkworm varieties. Based on the 2015, 2016 and 2017 regional multipoint test data of silkworm varieties from the annual summary reports on national registration, with the help of analyzing methods like nonparametric statistics, high stability coefficient and stability parameter together with the other common methods such as mean, standard deviation and variation coefficient, we conducted level comparison and stability analysis on the key appraisal indexes including cocoon yield per case of eggs, survival rate of pupa of silkworm varieties tested in rural production, and cocoon filament length, reelability, neatness of silkworm varieties tested in laboratory identification, which reflected the main traits related to yield, stability and silk quality of silkworm variety. The results indicated that all tendencies given by different methods were almost the same. The cocoon yield per case of eggs of Jin·Xiu×Xiao·Xiang was increased by 12.07% than that of the control variety Qiufeng×Baiyu. The new variety has the characteristics of high yield, excellent stability and superior silk quality, showing a good prospect in application and popularization.
