Gametic selection in a doubled haploid population derived from anther culture of indica/japonica hybrid of Oryza Sativa L.

It Is one of the key problems for application ofanther culture in hybrid breeding,geneticanalysis,and molecular mapping whether thedoubled haploid(DH)population derived fromanther culture of rice crosses represents a ran-dom array of the microspore population,i.e.whether gametic selection occurs in androgene-sis.A DH population including 132 lines de-rived from anther culture of a typical indicaand japonica cross,Zhaiyeqing 8/Jingxi 17(ZYQ 8/JX 17),was used to assess gametic
