【摘要】 对自ICR ISAT成套引进最新培育成功的早、中熟组木豆CMS杂交种各6份,进行了农艺性状及品质性状分析。结果表明:(1)早熟组的成株率高,育性恢复好;其中ICPH2363的成株率、单株荚数、百粒重等性状均表现较好。(2)中熟组中有2份杂交种在成株率、株高、分枝数等性状上远超对照品种;特别是ICPH3381的分枝数极显著多于对照品种。(3)早熟组杂交种的粗蛋白、无氮浸出物等指标普遍高于对照品种;特别是ICPH2364各品质性状指标均较高,干子粒平均单产也高于对照,作为精饲料、配合饲料开发利用潜力较大。木豆CMS杂交种资源农艺性状令人满意,在我国亚热带省区应具有较好的推广利用价值。更多还原

【Abstract】 Twelve newly developed pigeonpea CMS hybrid lines,6 from early maturity group and 6 from medium maturity group,were introduced from ICRISAT for analysis on agronomic and quality traits.The results showed:(1) Rate of plant formation and male fertility recovery in the early maturity group was high.ICPH2363 was the best in rate of plant formation,pods per plant,100-seed weight.(2) Rate of plant formation,plant height and branches per plant of 2 hybrid lines from medium maturity group,were much better than the control.The branches per plant of ICPH3381 were more significantly than that of the control.(3) The raw protein content and content of non-N extraction material in the early maturity group were higher than that of the control.ICPH2364 with high quality traits and higher dry seed weight than that of the control had huge potential in elite feeding meal and elite ingredient in the compound feed development.The agronomic traits of pigeonpea CMS hybrid lines was desirable.They have great potential in extending and utilizing in subtropical area of China.更多还原
