Studies on the Utilization of Heterosis in Mustard(Brassica Junces)

Shi Huaqing Gong Ruifan Zhuan Lilian Long Xiaoping (Oilseed Crop Institute of Yunnan Academy of Agricultural Sciences)  
A male sterile plant of mustard was found in 1973.After several years of study,ams line,European-Xinping A,a maintenance line,European-Xinping B,and arestoring line,74243-6,were successfully developed and a set of “three lines” was ac-complished in 1975.The set manifested high stability of sterility through successiveyears of study.The ms line European-Xinping A showed 100% sterility.The selfedseed-setting indexes averaged 0.000 to 0.103.The restored plant rate amounted to 99.54to 100%.There was fairly strong heterosis at the seedling stage with the F_1 hybrid,and heterosis also occurred in grain yield and oil content.The F_1 hybrid yielded19.2-34.8% more than the currently released elite variety Kunming-Gaoke,and was6.58-8.23% higher in oil content.Thus the gap that used to exist in the utilizationof mustard heterosis in our country has now been filled.In by the success of further re-search work in the utilization of heterosis of mustard.
