直播早熟优质甘蓝型油菜品种花油8号稳产性分析(英文)

Yield Stability of Direct-sowing and Early-maturing Excellent Brassica napus (Attar No.8)

[目的]对直播早熟优质甘蓝型油菜品种花油8号进行稳产性分析。[方法]在DPS软件下分析了2006-2009年云南省区域试验中花油8号的丰产性、稳产性和适应性，对其年度间、试点间的产量及主要经济性状进行了稳定性评价。[结果]花油8号品种3年24个点次平均产量达到3379．17k/hm2,其株型较紧凑，早熟性突出，着粒密、角粒数高，年度问产量差异不大；在云南8个不同生态条件下，均表现出较高的产量潜力，丰产稳产性突出，特别适宜云南乃至中国南方早熟油菜产区直播栽培。[结论]该研究结果为油菜丰稳产品种选育提供了参考依据。

[Objective] The aim was to analyze yield stability of attar No.8, which is direct sowing and early-maturing. [Method] Analysis was made on yielding ability, stability and adaptability of attar No.8 in Yunnan Province during 2006-2009 with DPS software and stability assessment was conducted on yield and major economic characters of the variety in different periods and experimental plots. [Result] Average yield of attar No.8 during three years in 24 plots achieved 3 379.17 kg/hm2; it grew tightly and is featured with early matureness. In addition, grain density, pod number and annul production differed little in different years and the variety in eight ecological conditions all showed high production potential, yielding ability and stability, which proved that attar No.8 is suitable to be grown in Yunnan and southern early-maturing areas in China. [Conclusion] The research provided references for selection and breeding of rapeseeds＇ variety which enjoys high and stable yield.
