| 摘 要： | 为加快改良我国现有玉米种质及其品种选育速度,推进国外材料的利用进程,对从泰国引进的12个玉米群体的农艺性状、产量性状、抗性、外观等进行考查比较。结果表明,12个泰国玉米群体株型均为平展型,株高219.15～234.06 cm,穗位高96.87～128.84 cm;12个群体产量均低于对照品种,其中群体Q1产量最高为7463.01 kg/ha,群体Q12产量最低为6418.31 kg/ha,方差分析结果显示,群体Q1、Q2、Q3、Q4、Q6、Q7、Q8、Q9间的产量差异不显著,而与群体Q5、Q10、Q11、Q12间的产量差异达到显著水平;各群体的出籽率、籽粒容重、穗粗、穗长、穗行数差异较小;千粒重275.67～307.00 g;行粒数均达到30粒,秃尖长度范围0.70～1.34 cm;12个玉米群体中,青枯病和纹枯病为主要病害,群体抗倒性均较强;果穗籽粒均为黄色,穗型为筒形,属硬粒型玉米,穗轴为白色。

| Abstract: | In order to accelerate the improvement of current maize germplasm,utilization of exotic maize germplasm and speed up varietal breeding,the agronomic and yield characters,resistance and appearance of 12 Thai corn populations were investigated.Plant type of 12 Thai corn populations were loosely type,plant height and ear height were found in the range of 219.15-234.06 cm and 96.87-128.84 cm,respectively.Yield of all the populations was lower than that of variety Zhengda 619(CK),yield of Q1 was the highest(7463... |
