息半夏不同种质资源的表型鉴定与评价
Phenotypic identification and evaluation of different germplasm resources of Xi Pinellia ternata
摘要
Abstract
17 Xi Pinellia ternata resource materials from 14 regions in Xi County,Huaibin County and Shihe District were collected to identify and evaluate their phenotypes.The results showed that there were 8 types of morphological characteristics among the Xi Pinel-lia ternata resources.Analysis of 12 quantitative phenotypic traits showed that the variation index of fruit number was the largest,at 44.328％,and the variation index of the growth period was the smallest,at 6.040％.Correlation analysis showed that there was a signif-icant positive correlation among 6 pairs of traits,and there was an extremely significant positive correlation among 5 pairs of traits.Principal component analysis simplified all phenotypic traits into four principal components,and the cumulative contribution rate was 74.32％.The cluster analysis could be divided into three groups:Group Ⅰ was suitable for screening the high-yielding Pinellia ternata;Group Ⅱ was suitable for screening Xi Pinellia ternata for seed breeding;Group Ⅲ was suitable for selecting Xi Pinellia ternata for bulbil breeding.Through comprehensive evaluation,XXBX1 could be used for high-yield Xi Pinellia ternata variety breeding;XX-BX6 could be used for seed breeding;HBBX16 could be used for bulbil breeding.关键词
