甘蓝型油菜与白芥杂种后代抗裂角性及其与角果性状的相关性
Silique shattering resistance in interspecific hybrids between Brassica napus and Sinapis alba
摘要
Abstract
To develop Brassica napus germplasm resources for mechanization breeding,hybrid progenies from B.napus and Sinapis alba were analyzed on silique shattering resistance,comparing with B.napus cv Yangyou 6.Random impact test demonstrated that silique shattering resistance index ranged from 0.14 to 0.99.The frequency distributions among the materials were 6,2,4,2,5,6,4 and 1,when the silique shattering resistance index was divided into 0.1-0.2,0.2-0.3,0.3-0.4,0.4-0.5,0.5-0.6,0.6-0.7,0.8-0.9 and 0.9-1 regions.It indicated wide variation in shattering resistance.Twelve lines demonstrated better resistance than Yangyou 6.Based on correlation analysis,the silique shattering resistance index had significant positive correlations with silique length,silique wall weight and thickness.Therefore,the long silique,thick and heavy silique wall could be used as auxiliary index to screen the silique-shatter-resistant rapeseed.关键词
