甘蓝型油菜DH群体抗裂角性的遗传分析
Inheritance of pod shatter resistance using a DH population in Brassica napus L
摘要
Abstract
Improvement of pod shatter resistance is the basic target for rapeseed breeding suitable for mecha-nized harvesting.To better understand the inheritance of pod shatter resistance in Brassica napus,a doubled hap-loid (DH)population was used in the study.Two parents of the population had contrasting pod shatter resistance levels.Pod shatter resistance index was determined using random impact test method in two years,and the inherit-ance was analyzed by major gene plus polygene genetic model for plant quantitative traits as well as the analysis of skewness and kurtosis.Results showed that the pod shatter resistance was controlled by 3 genes with major effects and 5 -7 polygenes with minor effects.There were major genes additive effects and complementary gene interac-tions.The heritability of major genes was greater than 85 .00%in both years,indicating pod shatter resistance was mainly controlled by major genes and less influenced by environments.Therefore,in breeding process for pod shat-ter resistance of rapeseed,pyramiding major genes from lines containing different major genes by hybridization and selection in early generation should be considered,and the influence of environmental factors can be ignored.关键词
