Pathumthani 1 is an aromatic non-glutinous and photoperiod insensitive rice. Its yield potential is up to 800-900 kg/rai under suitable fertilizer usage and cultural practices. Average yield on farm trail was damaged by flooding, brown planthopper and bacterial blight about 20 to 50 percent. Improvement of Pathumthani 1 for submergence tolerance, bacterial blight and brown planthopper resistance using molecular marker is one approach to solve this problem. This project was carried out under the commitment between the Rice Department and the Gene Discovery Unit of Kasetsart University. The experiments were divided into two parts, first part was crossing Pathumthani 1 and Pinkaset 1 to introduce bacterial blight resistance gene including Xa21, xa5 and...

KLG02008-19-2-4-3, an promising non-glutinous, non-photoperiod sensitive rice line had been derived from a cross of KLG96001-3-1-2 and SPR90. The improved rice had been developed through the conventional breeding and selection method. The single cross hybridization had been made in 2002 at Klongluang Rice Research Center. An promising line has an erect and moderately strong clum with about 120 centimeters for transplanting and about 112 centimeters for seed broadcasting, 118 days maturity for transplanting and 114 days for seed broadcasting. Its grain yielding potential is up to 1,052 kilograms per rai or more under suitably good fertilizer and cultural practice. The interstation yield trail in wet season 2010 obtained and average grain yield of...

Research was conducted in order to study the environmental effects on characteristic variation in the photoperiod sensitive rice varieties at Nakhon Si Thammarat Rice Research Center during 2011-2013. Rice varieties in the study were included Pathum Thani 1, Phitsanulok 2, RD31 and RD41. Results showed that rice grown in April having plant height, number of tillers per hill, number of panicles per hill and panicle length more than rice grown in January and July. The number of filled grains and yields were highest when grew in January. Rice grown in April had high percentage of unfilled grains. The influence of other climatic conditions did not show obviously effect on the growth of rice varieties in the study.
