1 自交系特征特性母本:植株长势旺,叶色深绿,成株健壮整齐,秆硬抗倒,根多发达,耐旱;雌雄穗发育协调,雌花花丝抽出时,雄花开始散粉。父本:植株长势旺,叶色灰绿,成株健壮整齐,雌雄较发达,分枝多,花粉量较大,花期长。雌雄出现较缓慢,在不良环境条件下,空秆率较高。

1 inbred line characteristics of the female parent: plant growth potential, dark green leaves, adult robust sturdy, hard stubborn stubborn, more developed roots, drought; coordination of male and female spikes, female flower filament extraction, the male flowers began to loose powder. Paternal: Plant growing vigorously, gray-green leaves, adult robust neat, male and female more developed, more branches, larger amount of pollen, flowering long.
