Abstract: 

A population consisting 59 advanced backcross lines (BC2F5) derived from a cross between IR64 and Tarom molaei, was studied in Chaparsar-Tonekabon Rice Research Station, Iran, in order to map the QTLs and determine the characteristics of QTLs for panicle length, number of full grain, number of empty grain, number of spiklet per panicle and grain sterility in rice. The parental polymorphisme was studied by 235 SSR markers in agarose and polyacrylamide gels, and 114 markers with clear polymorphic bands were selected for genotyping. Positive and negative transgressive segregationes were observed in BC2F5 lines for all traits. Using multiple interval mapping, 26 putative QTLs were detected, consisted eight for panicle length, three QTLs for number of spiklet, two QTLs for number of full grain, four QTLs for number of empty grain, and nine QTLs for grain sterility. More than 46 percent of QTLs had negative additive effects. The maximum number of QTLs were mapped in chromosomes 1 with six QTLs. Because of mapping more than one QTL for most traits, it is concluded that these traits are polygenic.
