云南芥菜型油菜品种具有抗旱耐瘠的特点，在我省山区旱地广泛种植，常年播种面积约3．33万hm2，占油菜总播种面积的35％－40％，占旱地油菜面积的60％左右。但因耕作粗放，加之缺乏具抗病力较强、优质、适应性较广的优良品种，故产量较低，严重制约着旱地油菜生产的发展。为了 Yunnan Brassica juncea varieties with drought-resistant barren characteristics, widely planted in dry mountain areas in our province, perennial planting area of ​​about 33300 hm2, accounting for 35% -40% of the total sown area of ​​rapeseed, dry rapeseed area accounts for about 60% . However, due to extensive farming, combined with the lack of a strong disease resistance, high quality, wide adaptability of the fine varieties, so the lower yield, severely restricted the development of dry rapeseed production. in order to
