【摘要】 从全国主要油菜育种单位引进11个优质双低杂交油菜组合,顺序排列,两次重复,鉴定其适应性、丰产性、稳产性和轻简(机播机收)高效栽培性状。结果表明:高产品种应筛选R0701,实收单产2 812.5 kg/hm2为最高,且抗倒、抗病虫、抗旱、抗渍,长势长相等综合性状较优;早熟品种应选择宁杂11号,该品种熟期较CK提前6 d,产量2 672.3 kg/hm2,在4个早熟品种中最高,且生育的一致性、抗逆性等综合性状均较好,成熟期集中,耐裂荚,株型适于机械收割,是当今轻简高效栽培的理想品种。更多还原

【Abstract】 Eleven hybrid rapeseed varieties with low erucic acid and low glucosinolate contents in rapeseed,introduced from whole China and planted in sequence with two replicates,were tested for adaptability,yielding,stability and other traits suitable for less-labouredly cultivation,i.e.,mechanical sowing and harvesting.The results indicated that the variety,R0701,has the highest yielding of 2 812.5 kg/hm2,tolerances to lodging,drought,water-logging and resistances to diseases and pests,and as well as well-growing situation features.The variety,Ningza 11,has the shortest season and can be harvested with 6 days early compared with the control.Among of four short season varieties,Ningza 11 has the highest yielding of 2 672.3 kg/hm2,being with the good uniformity of growing and resistance of adversities,super comprehensive traits,simultaneously maturation,tolerance to pod shattering,and plant type suitable for mechanical harvesting.Hence,it is presumed that Ningza 11 is an ideal variety for less-labouredly cultivation.更多还原
