文章应用TOPSIS综合评价法,以产量、基本苗、分蘖、有效穗、总粒数、实粒数、结实率、株高、穗长、千粒重为正向指标,全生育期、白粉病、蚜虫为负向指标,对参加2013-2014年度大麦省区域试验的大麦新品系进行综合评价,为下一步的登记和推广应用提供参考。研究结果表明某一品种的个别正向指标较小,该品种其余指标和其它品系差异较小,而负向指标较大,则该品种的综合评价较低;TOPSIS法对品种优劣评价的顺序与产量高低顺序不一致;大麦新品系的优劣与产量高低不一致,受实际生产需要和其它性状的制约;保大麦10-J5、保大麦11-J8、云饲麦8号、云13YD-16可在全省推广应用。
The TOPSIS comprehensive evaluation method was used to evaluate the effects of aphids on yield, basic seedling, tillering, effective spike, total grain number, grain number, seed setting rate, plant height, spike length and 1000-grain weight as positive indicators Negative indicators to conduct a comprehensive evaluation of the new barley lines in the regional barley provinces 2013-2014 test, which will provide reference for the next registration and popularization and application. The results showed that the individual positive index of a breed was smaller, the difference of other breeds of the breed was smaller than that of other breeds, while the larger the negative index, the comprehensive evaluation of breed was lower. The TOPSIS Which is inconsistent with the order of the yield. The new barley lines are different in yield and quality, and are subject to the actual production needs and other traits. The barley 10-J5, barley 11-J8, Yunmai 8 and Yun 13YD-16 Promote the application in the province.
