| Abstract | Chai Nat 1 (CNTBR82075-43-2-1), a non-glutionus rice, was derived from the cross IR13146-158-1/IR15314-43-2-3-3//BKN6995-16-1-1-2. It is a high yielding photoperiod insensitivity, 119-130 days in maturity, 113 cm height, just exserted panicle, and high nitrogen response. Its grain quality is straw hull colour, long slender grain with slight chalkiness, good milling quality, and high amylose content. It is resistant to major insect pests and diseases in central region of Thailand such as brown planthopper (Nilaparvata lugents), whilebacked planthopper (Sogatella furcifera), ragged stunt virus disease and blast (Pyricularia oryzae). Phitsanulok Rice Research Center therefore submis CNTBR 82075-43-2-1 to rice Research Institute to be an approved variety as the name Chai Nat 1 for solving the insect and disease problems of the farmers in the central region. |
