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
The results of 111 consecutive rapeseed varieties in different ecoregions in Chengdu winter rapeseed area for two consecutive years showed that 14 varieties of cabbage derived from VC4 6 75 and similar ecological regions in Chengdu were suitable for planting in the winter rapeseed area of Sichuan Province and the comprehensive agronomic traits were excellent, Among them, two high-yield and stable-yield varieties, VC4 6 10 and VC4 76 7, should be popularized. VC4 0 6 7, VC4 0 6 8 and other 2 mustard-type and cabbage-type VC3550 suitable for planting in mountainous areas in Sichuan. Varieties with a single fine agronomic trait, such as VC4 4 79, can be used as breeding material. The remaining varieties in the winter rapeseed area of Chengdu poor performance of agronomic traits, is not suitable for Sichuan cultivation and utilization. The test results show that the introduction of crops should be carried out in similar ecological range
