【摘要】 利用几个柱头外露率较高的品系与闭花授粉的大黑杂交,研究了栽培稻柱头外露性的遗传。试验表明,柱头外露性受一显性主基因(Ex)和一些微效基因所控制。通过连续回交和选择,已将籼型品系的柱头外露特性导入粳稻品种之中。更多还原

【Abstract】 Studies were made for inheritance of stigma exsertion in rice,Oryza saliva L.,using the hybrids between serveral lines with high percentage of exserted stigma(PES)and cleistogamous Daikoku.Stigma exsertion was controlled by a dominant gene Ex and some minor genes.It had been introduced from indica to japonica through successive backcrosses and selection.更多还原
