汉中地区属于冬油菜产区,过去曾推广甘兰型晚熟种胜利油菜,影响水稻插秧时间。七十年代先后选育出半冬性甘兰型中早熟品种早丰1、2号,使收种紧张的状况稍有缓和,但因品种退化感染白锈病,产量不够稳定。1974年育成的早丰3号,经过试验,表现高产早熟、抗病,适宜我区平坝、丘陵稻油两熟地区种植,1981年,全区种植约20万亩,占全区油菜总面积40％左右。一、选育经过 1967年以抗病、高产的甘兰型胜利油菜早熟选系62—177—1做母本,白菜型春油菜“拉鲁”做父本,进行类型间杂交,经六代单株选择育成,1978年定名。
Hanzhong belongs to the winter rapeseed production areas, in the past have promoted the type of late-ripening kulan-type rapeseed, affecting rice transplanting time. In the seventies, early-maturing varieties of semi-winter sweet orchid variety Zaofeng 1 and 2 were bred to slightly ease the tensegrowth of planting, but the yield was not stable enough due to the degenerative infection of white rust. Born in 1974, Fengfeng 3, after testing, showed high-yielding and early maturity, disease resistance, suitable for our area Pingba, hilly rice paddy areas planted in 1981, the region planted about 20 million mu, accounting for the total area of the region rape About 40%. First, the breeding After 1967 to disease-resistant, high-yield type of early victory of Brassica napus selection line 62-177-1 do female parent cabbage spring rape “Lalu” as the father of hybrids between types, after six generations Plant selection breeding, 1978 named.
