摘要: 为解决西藏本地荞麦农家品种退化、混杂严重,单产水平低等问题,2014年~2016年在拉萨引种13份荞麦品系进行鉴定和栽培试验,筛选出高产、稳定性好的优质荞麦品种。结果表明:参试品种不同年份产量差异呈极显著水平,平均单产以‘云荞2号’最高,为3597.6 kg/hm2,比对照增产51%;相关性分析表明,千粒重对产量影响呈正相关,差异较显著;高稳评价表明,产量水平高且稳定性和适应性好的品种为‘云荞2号’、‘西荞5号’;产量水平较高且稳定性和适应性较好的品种为‘晋苦荞2号’、‘云荞1号’。该研究旨在为西藏地区荞麦品种鉴定与示范推广提供理论依据。

Abstract: To solve the problem of buckwheat breeds degradation, hybridization seriousness, and low yield level in Tibet, 13 buckwheat breeds were introduced in Lhasa from 2014 to 2016, buckwheat breeds of high yield and stable quality were chosen by cultivation experiments. The results showed that the yield of planted breeds in different years had significant difference. And the average yield of‘Yunqiao No.2’was the highest, with an average of 3597.6 kg/hm2, which were 51% higher than that of control group. In addition, the yield was positively correlated with 1000-grain weight according to correlation analysis. The high stability evaluation (HSCi ) indicated that the breeds of‘Yunqiao No.2’and‘Xiqiao No.5’had the highest yield, stability and adaptability, while the breeds of‘Jinkuqiao No.2’and‘Yunqiao No.1’had the relatively high yield, stability and adaptability. The study provides a theoretical basis for the identification and demonstration of buckwheat breeds in Tibet.
