| Breeding for salt tolerant rice has been done for a decade. However, most of salt tolerant lines which have been released carry inferior cooking qualities compared to KDML105, an aroma good cooking quality rice of Thailand. To develop salt tolerant and good cooking quality rice, molecular marker assisted selection in backcross breeding program was initiated in 2001. Two RILs, FL496 and FL530 selected from mapping population of IR29 x Pokkali were used as salt tolerant donors. KDML105 as recipient was cross pollinated with these 2 donors to develop F1 and cross back to KDML105 to develop BC1F1. Three markers ; RM140, B1.1-1 and B1.1-11 flanking salt tolerant QTLs spanning 33 cM and two markers; RM00 and 10L03FW for amylose content and aroma scent were used... |
