- This study dealt with the identification and evaluation of 8 maize populations from tropical and subtropical regions under the ecological conditions in zhengzhou , henan . results showed that the significant delaying days to shed and days to silk , discoordinating for the development of male and female , higher plant and ear height , more leaf numbers , high barreness , worse performance of ear traits compared with the ck ( temperate population ) were found , which showed the tropical and subtropical populations could not be utilized directly under the ecological conditions in zhengzhou . by using selection and improvement the tropical and subtropical populations can be used to broaden the genetic base of temperate maize breeding , beause of the greater genetic variation and higher selection potential within each population . the different performances of the sensitivity to photoperiod were observed among different tropical and subtropical populations and different traits . the asi , time to silk , ear height , leaf numbers , grain yield per ear could be used as the good evaluation traits for identifying the sensitivity to photoperiod
对8个热带、亚热带玉米群体在郑州生态条件下的表现进行鉴定和评价，结果表明，热带、亚热带群体散粉、吐丝期显著延迟，雌雄不协调，植株和穗位高、叶片数增多、空秆率高，结实性差，果穗性状均明显劣于温带对照，在郑州生态条件下不能直接利用，但是群体内具有较大的遗传变异和选择潜力，可以用来拓宽现有玉米种质的遗传基础；不同热带、亚热带群体的光周期敏感性不同；不同性状对光周期反应的敏感程度不同， asi 、吐丝期、穗位高、叶片数、穗粒重可作为鉴定光周期敏感性的较好指标
