    摘要:

    谷子穗粒重和穗长遗传变异系数比较大,秆高变异最小。估算广义遗传力,秆高、小区产量、穗重较大,一穗小码数最小。秆高、穗长、穗重、穗粒重与小区产量和穗长、穗重、穗粒重与秆高,以及穗重、穗粒重与穗长均呈极显著正相关。在5%的选择率下,各性状的遗传进度顺序是穗粒重→穗长→小区产量→穗重→一穗小码数→千粒重→秆高。以秆高与穗长,秆高、穗长、穗重、穗粒重性状组合选择指数的效果为佳。

    Abstract:

    Estimate of genetic c.v. of grain wt. per spike and spike length were the higher and plant height the lowest. Then, the plant height, plot yield, spike wt., spike length, grain wt. of spike, 1000 seed wt., and spikelet number per spike followed each other. In order of sign of hb2 there are significant positve correlation between plant height, spike length, spike wt., grain wt. per spik and plot yield, between spike length, spike wt., grain Wt. per spike and plant height, between spike wt., grain wt, per spike and spike length. In order of sign of genetic advance there were grain wt. per spike→spike length→plot yield→spik wt. →spikelet number per spike→1000 seed wt. →plant height, Good selected effects of selected index combined with plant heigth+spike length or plant height+spikel ength+spike wt.+grain wt. per spike.
