Abstract:

Comprehensively identificated a group of high-quality and early-maturing rapeseed, in Guangxi province from 2009 to 2010, about its high-yield, resistance and regional adaptability in north region of Guangxi province. The tests were completely random group, repeated three times. The quarter net area was 13.2 m2, the basic miller was 120000 strain/hm2. The results tested the yield of the high-yield rapeseed, its economical trait and growth stage and disease resistant. The results showed superiority of rapeseeds ‘Shilifeng’, ‘Fengyou737’, ‘Zheyou18’, ‘Yunyoushuang2’ and ‘Yunhuayou9’ over other rapeseeds as revealed by high yield , strong resistance and suitable for planting in double cropping rice areas in Guangxi province, ‘Baihua09sw01h’, ‘Huayou5’, ‘Yunyouza2’ and ‘Huayou8’were unsuitable for extension in Guangxi province because of their low yield and lesser resistance, the other rapeseeds had relatively lower yield or reasonably lesser resistance, and need to be further tested.
