| 摘 要： | 对来自墨西哥国际玉米小麦改良中心（ＣＩＭＭＹＴ）的９个抗旱玉米群体进行引种试验，研究了其９个性状。结果表明，这批群体的散粉至抽丝间隔（ＡＳＩ）都极显著地比广西推广的品种墨白１号（对照）为短。各群体中有一个群体的单株粒重显著高于对照，有５个群体与对照无显著差异。再综合考虑其他性状，认为有希望从这批群体中选育出抗旱性、产量等综合性状较好的群体，在生产中直接应用。

| Abstract: | The introduction experiment of 9 drought--tolerant corn (Zea mays L.) populations from CIMMYT were conducted, and 9 characters of them were studied. The results show that the anthesis-silking intervals (ASI) of these populations are all shorter significantly than that of the contrastive population planted in Guangxi, Mobai-1. The grain weight per plant of one population in them is higher than the contrast (Mobai-1) and no significant differences are found between 5 populations and the contrast. It is concluded, by considering other characters synthetically, that some populations have better drought tolerance, higher yield,and other better characters can be developed from these populations and applied directly in practical field production. |
