Improvement of pod shatter resistance is the basic target for rapeseed breeding suitable for mechanized harvesting. To better understand the inheritance of pod shatter resistance in Brassica napus,a doubled haploid( 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 inheritance was analyzed by major gene plus polygene genetic model for plant quantit...
