摘要
本研究通过分析栽培大豆与野生大豆杂交后代农艺性状及其与产量的相关性,研究影响大豆产量的农艺性状,并对各株系进行综合评价。在通辽市科尔沁左翼后旗查金台牧场野生大豆和大白眉种间杂交后代中,选取18个性状稳定的株系对其20个农艺性状进行因子分析,结果表明:杂交后代各株系的农艺性状存在显著差异;经因子分析提取到5个公因子,其累计方差贡献率达73.611%,表明所选的5个公因子可以较好地反映20个性状所包含的信息;三粒荚数、一级分枝数、茎秆重、有效分枝数等农艺性状可作为评价大豆产量的依据。筛选出具有进一步推广价值的5个株系(15、3-2-2、^(60)Co 600、18-2、8-1-2),为利用和保护野大豆资源及改良栽培大豆提供理论依据及基础材料。
The correlation analysis of yield of progeny lines derived from cultivated soybean × wild soybean and their agronomic characteristics were performed to assess these lines and their agronomic characteristics affecting soybean yield. 20 agronomic characteristics of 18 stable progeny lines were analyzed by factor analysis. The quanti-tative trait analysis of plant and seed of progeny lines showed that the agronomic characteristics of each line had sig-nificant difference. 5 common factors were extracted by factor analysis, and the cumulative variance contribution rate was 73.611 % . This result indicated these 5 common factors could primely reflect the information of these 20 traits, and the factor analysis was reliable for assessing the effect of agronomic characteristics on yield. Integrated assessment of each line and its agronomic characteristics was used to screen out 5 lines of promotional value. The results showed that agronomic characteristics such as three - pod number, first - class branch, stem weight and ef-fective branching could be used for evaluating soybean yield. 5 lines including 1 5 , 3 - 2 - 2 , ^60Co 600 ,18 -2 and 8-1-2 were selected for further promotion, which could help to utilize and protect wild soybean resources.
