有关作物数量性状的配合力、遗传力的研究,在玉米、水稻、小麦等作物中报道较多。油菜方面印度学者曾对芥菜型和白菜型油菜进行过一些研究。近年来,我国学者对甘蓝型油菜主要经济性状的遗传力、遗传进度等进行了研究。为了探讨国内外芥菜型油菜主要经济性状的遗传规律,为育种工作提供一定的信息,使杂交育种工作能较好地选配亲本和确定杂种选择的世代,作者用六个国外芥菜型品种与五个当地芥菜型品种(系)组成6×5不完全双列杂交,估算了全株角果数等性状的配合力、遗传力等遗传参数,为确定选择方法提供参考。
Studies on the combining ability and heritability of the quantitative traits of crops have been reported in crops such as corn, rice and wheat. Indian scholars in rape have done some research on Brassica juncea and Brassica campestris. In recent years, Chinese scholars have studied the heritability and genetic progress of the main economic traits of Brassica napus. In order to explore the genetic laws of the main economic traits of Brassica juncea at home and abroad, to provide some information for breeding work, so that the crossbreeding work can better select the parents and determine the generations of hybrid selection. The author used six foreign mustard- A total of 6 × 5 haplotypes of B. juncea were used to estimate the combining ability and heritability of the characters such as number of pods in whole plant so as to provide reference for the determination of selection methods.
