引言狼尾草(Pennisetum clandestinum Hochst ex Chiov)雄性不育属无雄蕊型,其不育过程的形态学变化前人已有许多研究报道。但有关雄性不育性的生理学和遗传学研究资料甚少,Narayan(1955)从相应的一些非控制杂交组合的结果推论:雄性不育性受隐性基因控制。Carr等(1956)认为这一结论未必正确,由于雄性不育性对于
INTRODUCTION Penicillium (Pennisetum clandestinum Hochst ex Chiov) is a non-stamen male sterility. The morphological changes of its male sterility have been reported in many studies before. However, little is known about physiological and genetic studies of male sterility. Narayan (1955) deduced from the results of the corresponding non-controlled hybrid combinations that male sterility is controlled by a recessive gene. Carr et al. (1956) concluded that this conclusion may not be correct because of male sterility
