低芥酸油菜新品系是贵州省农科院油料所于1976年用黔油九号作母本,加拿大低芥酸油菜作父本,进行人工杂交后经贵阳、昆明两地多年加代定向选育而成的低芥酸油菜新品系。 特征特性:该品系于叶肾脏形,幼苗直立,叶色深绿,叶面光滑无刺毛,腊粉少.根系发达,茎杆灰绿、坚实分枝部位低,株型较紧凑,花冠中大,花瓣黄色、较大,角果长大,稍斜生,子粒黑褐色。该品系为半冬性偏春性,生长势强,冬春双发。一般5月上中旬成熟,全生育期192～219天。株高124～181.9厘米,一次有效分枝6～9个,最多可达14个,二次分枝数少,只有1.9～4.6个,分枝部位中高。主花序长45～63厘米,结角数,角长7～10.2厘米,每角15～22粒,千粒重3.8～5.2克,含油量36.37～40.71％,原种芥酸含量接近于0。抗倒及耐病能力较强,适应性广。 栽培技术:由于该品系冬前生长较快,不宜过早播种。一般直播在阳历10月上旬为宜,最迟不得晚于中旬播种。育苗移栽可在9月下旬播种,苗龄掌握在30～40天,以35天为宜,苗床播种量不宜过大,每亩播种
Low erucic acid rapeseed line is the Guizhou Provincial Academy of Agricultural Sciences fuel in 1976 with Qianyou 9 as the female parent, Canadian low erucic acid rape as a male parent, after artificial cross after Guiyang, Kunming, two years of generations of targeted breeding The resulting low erucic acid rape new line. Characteristics: The strain is leaf kidney shape, the seedling is upright, the leaf color is dark green, the leaf surface is smooth and without burr, the wax powder is less.The root system is developed, the stem is gray-green, the solid branch is low, the plant type is compact, Large, petal yellow, larger, angle fruit grow up, slightly oblique, grain dark brown. The line is semi-spring partial spring, growing strong, winter and spring double hair. Generally mature in mid-May, the whole growth period of 192 to 219 days. Plant height 124 ~ 181.9 cm, an effective branch of 6 to 9, up to 14, the number of secondary branches less, only 1.9 to 4.6, branches in the high. The main inflorescences are 45-63 cm in length. The number of knots is between 7 and 10.2 cm in length and 15-22 in each corner. The grain weight is 3.8-5.2 g and the oil content is 36.37-40.71%. The original erucic acid content is close to zero. Anti-down and disease-resistant ability, wide adaptability. Cultivation techniques: As the strain grows fast before winter, it is not advisable to sow it too early. General live in the Gregorian calendar in early October is appropriate, no later than mid-sowing. Seedling transplanting can be sown in late September, seedling age at 30 to 40 days to 35 days is appropriate, seedbed seeding rate should not be too large, sown per mu
