Abstract

Three objectives of the project of rainfed lowland rice was emphasized for 1st to add up the necessary phenotype with resistance to the important insects and diseases, well develop in restrict environment, high yielding ability and maintain the good taste good cooking properties to the favorite varieties RD6, KDML105 and RD15. 2nd to diversified genetic background with high yielding ability 1 or 2 promising line and 3rd to purified the popular local varieties and put into the highend market. Rice breeding for a new variety with good quality for consumers and resist to insects and disease was continue keep on, but mostly result in fail objective sometime get good quality but not resistance or sometime get a resistance one but not good quality. It was necessary to looking for the good new donors or good parent materials and plus the good character together and using of MAS method is more exactly correct and rapid means than conventional method. But the new progeny still segregate and necessary to evaluate by the skillful professional researcher with conventional selection, and need the cooperate with many disciplines to evaluate response of environment and qualified adoption of consumer or the other stakeholder make decision and recommend the grower to follow information. Another progeny in the program with a good character was still carry and use in breeding for next generation. It was necessary to evaluate the popular local varieties and purify for appropriate utilization and put into the niche market.
