The Breeding of the Recessive Epistatically Genic Male Sterile Hybrid Rapeseed--Wanyou 18 with Double Low

Chen Fengxiang et al (Crop Research Institute, AAAS, Hefei 230031)  
New rapeseed combination-Wanyou 18(Brassica napus), the third hybrid with strong heterosis in B. napus by recessive epistatic GMS, was examined and approved by the State Variety Commission in 2002. The yield of Wanyou 18 was about 8%-10% higher than that of Qinyou 2 and about 15% higher than Zhongyou 821. Wanyou 18 had higher resistance to diseases than Qinyou 2 and Zhongyou 821, high resistance to cold and stalk leaning and good fertilizer tolerance. The growth duration of Wanyou 18 was about 225 days, which were 3-4 days shorter than Qinyou 2 and 1-2 days longer than Zhongyou 821. The content of oil was 43.04%; erucic acid, 4.92% and glucosinolate, 28.54 umol/g meal. In a word, Wanyou 18 was a double low rapeseed hybrid with good integrated agronomic characters, which was with high yield, stable yield, extensive adaptability, good planting pattern and high economic coefficient. It was suitable for planting in the middle and lower reaches of Yangtze River.
