【摘要】 全国不同生态区 111份油菜品种在成都冬油菜区连续两年重复试验结果表明 ,来源于与成都相似生态区的VC4 6 75等 14份甘蓝型品种适合四川冬油菜区种植 ,综合农艺性状优秀 ,其中VC4 6 10、VC4 76 7等 2份高产稳产品种应重点推广。VC4 0 6 7、VC4 0 6 8等 2份芥菜型及白菜型VC3550适于四川山区种植。具有某一单项优良农艺性状的品种如VC4 4 79可作为育种材料利用。其余品种在成都冬油菜区农艺性状表现差 ,不适合四川种植利用。试验结果证明作物引种应在相似生态区间进行更多还原

【Abstract】 rapseed varieties from different ecological regions of China were planted in 1997～1998.14 varieties of B.Napus L among them,such as VC4675 from the ecological regions similar to Chendu,were adaptive to Sichuan.And their comprehensive agronomic traits were very good.The two varieties VC 4610 and VC4067 of them,especially, had high and stable yields,and should be popularized in hill and plain aera of Sichuan.VC4067 and VC4068 of B.Juncea L and VC 3550 of B.Campestris L can be introduced to Sichuan mountain area.The varieties with single good agronomic trait,such as VC4497,can be used as parent materials in rapseed breeding.The comprehensive traits of other varieties were very bad and not adaptive to Sichuan.The result proved that the introducton of crops should be carried out between the similar ecological regions.更多还原
