Abstract

Some parts of an irrigated area in the upper northern region, rice cultivation will be done in both dry and wet seasons. Glutinous rice varieties are still preferable for farmers due to high yield and suitability for people’s cultural consumption. To enhance the growth of rice production, the researchers of Rice Research Center in the region have been conducted the research and development on rice varietals improvement continuously to gain the desirable new varieties. The results showed the dominated 2 new promising glutinous rice lines, PRE96016- SPT-25-2-2-1-1 and PRE98002-PAN-B-1-3-3, by crossing method of IET 12011/SML and KKNLR75051-PMI-68-1/PHRAE1 for each lines respectively. Both lines showed the potential of the highest (948 and 934 kg/rai respectively). Characterizations of seed and plant type are, slender grain with rice straw in color, moderated to good in milling quality, the percentage of broken rice and head rice between 32.0-56.8 and 31.3-53.3%, the alkali test values grain in KOH are low (6.6 and 6.2) respectively, resistant to blast disease, moderately resistant to bacterial leaf blight disease, but not resist to gall midge and white backed plant hopper.
