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...

This research was continued from the Marker Assisted Selection (MAS) backcross breeding program for improve CNT1 to resist to BPH by introgressed a Bph3 resistant gene from K/R IL into CNT1. A population was already done in BC3F1. This study was attempted to develop BC4F1-BC4F3 and validated BPH resistance in improved lines. Two markers, RM170 and RM190 which linked to Bph3 gene and plant type were going together used for selecting the target plants. Twenty heterozygous BC4F1 and eighty three homozygous BC4F2 plants were selected. Finally, seventy seven BC4F2 lines carrying Bph3 were used for BPH evaluation with 3 BPH population from Phitsanulok, Tak and Pathum Thani. The results showed that almost improved lines were higher resistant to BPH than CNT1 and...

Rice blast is a one of the most important rice disease. It could cause severe yield damage. Therefore, it is vital for rice improvement aiming for blast resistance especially for those containing as good cooking quality as Khao Dawk Mali 105 (KDML105); Khao’ Jao Hawm Phitsanulok 1 (HPSL1) belongs to this group except a slightly longer maturity than that of KDML105. Nowadays, molecular technology has been used for a greater efficiency in selection through a marker assisted selection. DNA primers specific to gene(s) or QTLs related to rice blast defense mechanism were developed. In this study, a cross between HPSL1 and two donors; P280-2 and P280-5 was carried out. These donors contain blast resistance genes on chromosome 1, 2, 11 and 12 identified by 6...

Amplified fragment length polymorphism (AFLP) and biotype-specific markers were used for identification of genetic diversity and biotypes of rice gall midge, Orseolia oryzae in Thailand. Pupae and adults of the gall midges were collected from 19 field locations of 12 provinces during 2006 - 2007. Total of 242 polymorphic AFLP bands were generated from 12 selective primer pairs. Cluster analysis, performed by the UPGMA, separated the gall midge populations into four distinct groups. To identify the biotype, five specific-biotype markers were used to characterize the collected gall midges. Two biotypes of the gall midges, biotype 2 and 5, were identified from all populations used in this research. The results showed that the genetic diversity was not...

Major quantitative trait loci (QTL) associated with basal root thickness (BRT) on chromosome 4 was used as the target for physical mapping. Two parental rice lines contrasting in their root characteristics, CT9993-5-10-1-M (CT) and IR62266-42-6-2 (IR), were used in this study. The objectives of this study were to fine map the major BRT QTL on chromosome 4 in rice and to isolate candidate genes related to root penetration index (RPI) trait which located in this region. The BAC library available for screening in this study was constructed from a rice cultivar Nipponbare (japonica) with average insert sizes of 130 to 150 kb and with a 10X genome equivalent. The RFLP markers located near the target BRT QTL on rice chromosome 4 were used for screening BAC...
