早熟油菜新品种“湘油420”的引进试验示范初报

Preliminary Report on Introduction and Demonstration of The New Early Maturing Rapeseed Variety ‘Xiangyou 420’

为了丰富西藏半高寒农区油菜品种类型,西藏自治区农业研究所从湖南农业大学引进双低、优质甘蓝型油菜品种"湘油420",该品种芥酸含量为0,硫苷含量17.39 umol/g,含油量40.08%。在西藏海拔3 658~3 970 m进行2年试验示范,结果表明,"湘油420"表现为成熟早,抗旱、抗寒性强,产量高的特性,生育期121~134 d,平均产量133.61 kg/667 m^(2)。该品种适宜在西藏河谷农区及半高寒农区种植,可作为西藏半高寒农区白菜型油菜品种的替代品种进一步扩大示范面积。

In order to enrich varieties of rapeseed in semi Alpine agricultural region of Tibet,the agricultural research institute of Tibet Autonomous Region introduced the double low and high quality rapeseed variety‘Xiangyou 420’ from Hunan Agricultural University. The content of erucic acid and glucosinolate are 0 and 17.39 umol/g,and the oil content is 40.08%. The experiment was carried out in two-year and three-point with 3 658~3970 meters above sea level in Tibet. The results showed the cultivar the characteristics of early maturity,strong resistance to drought and cold,and high yield,with the growth period 121~134 days,and the average yield 133.61 kg/667 m^(2). It was suitable for planting in the Valley agricultural and semi Alpine agricultural area of Tibet. It could be used as an alternative variety of Brassica campestris in semi Alpine agricultural region of Tibet to further expansion of the demonstration area.
