摘要:
利用以“闽紫7号”紫云英为母本、“信阳种”紫云英为父本获得的F4代群体,评价了该群体18个株系的农艺性状和养分吸收状况,为筛选优异紫云英株系做参考。结果表明,在盆栽条件下,不同株系紫云英在盛花期表现出一定的性状变异。相关性分析表明,鲜重、干重与氮、磷、钾积累量相关性高,对植株的养分吸收影响较大;株高、分枝数、真叶数是影响植株地上部鲜重、干重的重要因素。主成分分析表明,地上部鲜重、干重以及地上部氮、磷、钾积累量是反映紫云英株系性状优劣的主要指标。聚类分析结果显示,当距离系数d=25时,18份紫云英材料可分为3类,其中Ⅰ类群综合性状最优,包括m83xzh-1-4-4、m83xzh-1-4-6、m83xzh-1-4-8和m83xzh-1-4-13共4个株系。综合考虑紫云英生长性状、鲜草产量及植株养分积累量等因素,m83xzh-1-4-4的地上部磷、钾积累量和地下部氮、钾积累量最高,每盆分别高达11.00 mg,145.18 mg,22.15 mg和15.27 mg,同时该株系具有较高的鲜草产量,每盆高达44.63 g。本研究可为后续按目标性状选育紫云英新品种提供参考。
