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。 6 sets of 6 hybrid CMS varieties of early and midrib were successfully introduced from ICR ISAT. Agronomic traits and quality traits were analyzed. The results showed that: (1) The rate of mature plant was good and the fertility was restored well in early maturing group. Among them, the rate of plant, pod and weight per plant of ICPH2363 performed well. (2) There were 2 hybrids in Zhongshu group that far exceeded the control varieties in the rate of plant, plant height, number of branches and so on. In particular, the number of branches of ICPH3381 was significantly more than that of the control. (3) The indexes of crude protein and nitrogen-free extract of early-maturing hybrids were generally higher than that of the control varieties; especially, the indexes of quality traits of ICPH2364 were higher, the average yield of dry seeds was also higher than that of the control Potential for greater use. The agronomic traits of the CMS hybrids of Cydonia macrocephala are satisfactory, and should be well popularized and utilized in the subtropical provinces of our country.
