Abstract: Khao Dawk Mali 105 ( KDML 105 ) variety is a widely acceptable rice variety among farmers and consumers in terms of good grain and cooking quality plus aroma. Therefore, certainly, its price is a lot higher than the others both in local and world markets. Moreover, it also was pointed out that KDML 105 has intermediate tolerance to salinity and drought. To increase yield of KDML105 to be grown in saline soil area, where as all good traits are maintained, rice research centers located in the Northeast started the program in 2001 with backcrossing method. KDML105 was used as recipient parent, whereas the inbred lines immerged from the cross between IR29 tolerant variety) was the donor parent for saline soil tolerant trait. Consequently, the lines derived from each cross were monitored for the salinity tolerance by molecular marker which closely links to the and Pokkali (saline soil tolerant gene/genes). The population were developed until BC2F3 and BC3F2. The selected lines from the generations were planted in preliminary observation nursery in 2003. Furthermore, BC2F5 and BC3F3 selected materials were planted in observation nursery conducted in saline soil area located in the area of responsibility of Sakon Nakhon in 2005 and Pathumthani Rice Research Center in 2004 and in 2006, the evaluation of adaptability of 104 lines/varieties derived from the project was conducted in Chum Phae Rice Research Center. The tillering ability, number of panicles per hill, height, maturity and grain yield of these lines and varieties were observed. Most lines had agronomic performance similar to KDML105. The steps of improvement will be carried on in the following years.
