| 摘 要： | 采用模糊数学综合评判方法,以千粒重、穗粒数、籽粒饱满度和株高为评价因素,对旱地选种圃中选10个F_2组合进行了综合评价．结果表明,所有组合综合指标值均高于对照品种,其中最佳组合3个,一般组合3个,较差组合1个．该方法定量地评价了F_2代组合优劣及其群体中各类单株比率和组合的选择潜力,为进一步在F_3代株系群体中评选优势系群提供了信息． |

| Abstract: | Using fuzzy mathematics comprehensive judgement method,1000-grain weight, grains per spike,grain plumpness and stem length being assessment element,ten hybrid combi- nations F_2,selected from dry land nursery of hybrid,were comprehensive assessed.The result showed that,the comprehensive index of all combinations is higher than the contrast;the numbers of the best,normal and relatively poor combinations are three,three and one,separately.Using this method can evaluate quantitatively F_2 excellent or not,different individual rate in colony and choice potential of every combination.And this can offer information to evaluating superior line group in F_3. |
