杂交油菜新品种扬优8号的特征特性及栽培技术

The Characteristics and Cultural Technical for Yangyou NO. 8 (Brassica napus L. ), a New Double low Varieties of Hybrid Rapeseed

杂种优势利用是提高油菜产量水平的重要手段。为了提高油菜产量及产油量,江苏里下河地区农科所利用油菜细胞质雄性不育系,经过近十年努力,选育出杂交油菜新品种扬优8号。该品种在江苏省区试中,表现突出:产量高,一般产量可达200kg/667m^2;稳产性好,参加试验的几年间产量变幅小;品质优,符合国家双低标准;抗逆性较强。是一个优秀的杂交油菜新品种。为了配合该品种的推广应用,对其相关高产保优栽培技术进行了研究,并提出了具体的栽培措施。

The Heterosis Utilization is the important method of raising the rapeseed production level, m order to improve the rape output and oil yield, Jiangsu Institute of Agricultural Science in the Lixiahe District used rapeseed cytoplasm male-sterile line, success to breed the new hybrid rapeseed variety, Yangyou NO.8. In the multi-site regional trail of Jiangsu provincial hybrid rapeseed, its performance prominent： The yield is high, the general output may reach 200kg/667m^2; stability is good, the output amplitude is small during several years in the multi-site regional trail; Its quality is superior, conforms to the national double low standard; The resistance is stronger. It Is an outstanding hybrid rape new variety. In order to promote the variety application, correlation high production research was conducted, and propose the concrete cultivation measure.
