【摘要】 通过引进13个油菜品种(组合)在西藏山南市开展品种比较试验，对比引进品种生育期、农艺性状、产量、品质与西藏品种的差异，考察引进品种的价值。结果表明：有6个引进品种较对照增产，其中O95A×20B、P20A×希望990、希望152、O759A×希望990增产幅度较大且品质较优，建议对这4个油菜品种(组合)开展生产试验示范，进一步考察引进品种在西藏的生产和推广运用价值。更多还原

【Abstract】 A variety comparison experiment was conducted to compare the difference of growth period, agronomic traits, yield and quality between 13 introducing rape cultivars(combinations) and local Xizang cultivars in Shannan Area of Xizang.The results showed that 6 cultivars had higher yield than the CK and 4 cultivars(O95A×20B, P20A×Xiwang990, Xizang152, O759A×Xiwang990) showed significant increases in yield and superior quality. It was recommended to carry out field demonstrations for these 4 cultivars to further investigate their production and the value of promotion and application in our region.更多还原
