摘要:
为促进德州地区夏播小豆新品种选育及高产栽培，选取83份夏播小豆品种(系)，分成早熟、中熟、晚熟3组，研究小豆生育期结构与农艺性状的相关性。结果表明，随着熟期的延迟，不同生育类型小豆的出苗-分枝期天数没有显著变化，分枝-开花期、生育前期和生育后期天数均显著增加，其中生育后期天数增加的幅度高于生育前期，且生育后期对全生育期的影响大于生育前期；小豆的株高、主茎节数、单株粒重、百粒重和产量随着熟期的延迟呈增加的趋势，在不同生育类型间株高、百粒重和产量差异显著，分枝数和单株荚数差异不显著；单株粒重和百粒重是影响产量的主要因素，单株粒重与全生育期呈显著或极显著正相关，百粒重与分枝-开花期和生育前期天数呈极显著正相关。综上可知，分枝-开花期、生育前期和全生育期天数是影响夏播小豆农艺性状和产量的主要因素。
Abstract:
In order to promote the breeding and high-yield cultivation of new summer-sown adzuki bean varieties in Dezhou, Shandong, 83 varieties (lines) of summer-sown adzuki bean were selected and divided into three groups: early maturing, medium maturing, and late maturing. The correlation between the growth period structure of adzuki beans and their agronomic traits were studied. The results showed that, with the delay of maturity,the days of branching-flowering stages, earlier growth period and the later growth period gradually increased,the days of later growth period were higher than the earlier growth period,and the influence on whole growth period was greater than the earlier growth period,but there was no significant difference on the germinating-branching period among different growth-period types;The plant height，node number of main stem,seed-weight per plant,100-seed weight and yield all increased with the delay of maturity,the differences were significant on plant height,100-seed weight and yield,but not significant on number of branches or number of pods per plant;Seed-weight per plant and 100-seed weight were the main factors affecting yield. The seed-weight per plant was significantly or extremely significantly positively correlated with the whole growth period,and the 100-seed weight was extremely significantly positively correlated with branching-flowering stage and early growth stage. In conclusion,branching-flowering stage,early growth stage and the length of the whole growth period were the main factors affecting the agronomic traits and yield of summer-sown adzuki bean.
