Breeding of Early Maturing Rapeseed (Brassica napus L.) Cultivar ‘Xiangyou 420’
摘要
Abstract
Early -flowering individuals of the rapeseed cv.‘Zhongshuang 9’were used as female to cross with cv.‘Xiangyou 15’as male.The resultant progenies were selected for early maturity by shuttle breeding between Changsha and Kunming.The bred cultivar named 420 matures around April 20 owhen sown around October 20 of the previous year in Changsha(Central Hunan),which is 15 -20 days earlier than conventional cultivars even under the condition of 30 days delay of sowing.This cultivar is of double -low quality,with erucic acid and glucosinolates content of 0 and 17.39 μmol/g.It has oil content of 41.08% in its seed.The plant height is about 155 centimeters at high density of 450 000 plants per hectare.The cultivar ‘Xiangyou 420’is an excellent rapeseed by direct sowing in the cropping system of yearly rapeseed-early rice -late rice.关键词
