核优46系安徽省农业科学院作物研究所利用隐性上位互作核不育系Y204A作母本,与自交系049003组配育成的高油抗逆强优势杂交油菜新品种。该品种属半冬性双低甘蓝型油菜,2009年通过安徽省品种审定委员会审定。安徽省油菜区试两年平均亩产191.42 kg,较对照皖油14增产7.0%。全生育期平均230.1 d,比皖油14号早0.4 d。株高平均171.6 cm,有效分枝部位适中,平均43.6 cm,结角密,平均1.25个/cm,主花序长平均69.5 cm,有效分枝较多,一次分枝平均9.7个,二次分枝平均6.9个,全株有效角果数多,平均482个,平均每角粒数20粒,千粒重4 g,种皮褐黑色。省区试平均芥酸含量为0.45%,硫甙含量为20.38μmol/g饼,含油量为43.75%。抗病性、抗寒性强,明显优于对照;抗倒性中等。该品种地区适应性广,适宜安徽省油菜产区种植。
Nuclear Excellent 46 Department of Crop Sciences, Anhui Academy of Agricultural Sciences using recessive superior interlabelled male sterile line Y204A as a female parent, and inbred lines 049003 group bred high oil resistance strong heterosis rapeseed new varieties. The variety is a semi-winter double-low Brassica napus, in 2009 through the approval of the Anhui Provincial Commission for approval. Anhui rapeseed area average annual yield of 191.42 kg two years, compared with the control of Wanyou 14 yield 7.0%. The whole growth period averaged 230.1 days, 0.4 days earlier than that of Wanyou 14. The average plant height was 171.6 cm with an average of 43.6 cm of effective branches and an average of 1.25 knots per cm. The main inflorescences grew an average of 69.5 cm with more effective branches with an average of 9.7 primary branches and secondary branches An average of 6.9, the whole plant effective number of pods and more, an average of 482, the average number of grains per square 20, 1000 grain weight 4 g, the seed coat brown. The average erucic acid content was 0.45% in provinces and autonomous regions, the glucosinolate content was 20.38 μmol / g, and the oil content was 43.75%. Disease resistance, cold resistance, significantly better than the control; lodging resistance medium. The varieties of wide adaptability, suitable for planting rape in Anhui Province.
