| Rice gall midge (GM) is an important insect pest in the upper north of Thailand i.e. Tak, Phrae, Lampang, Nan, Phayao, Mae Hong Son, Chiang Rai and Chiang Mai provinces. Severe infestations generally occur during September to October. Prior to this study, only MN62M and RD4, the two glutinous rice varieties were recommended as resistant ones. Hence, the non-glutinous type with resistance to GM is in urgent need. The research has been conducted for 12 years during 2001 - 2012. The cross was made between PRE92039-3-1-2-1 and SPT82022-PRE-26-3-2-GM-6. Populations were selected continuously from F2 to F6 after which study and evaluation were carried out in successive steps from observational nursery, intra-station yield trial, inter-station yield trial and... |

| Reaction of PRE01017-10-1-1-1 rice promising line to gall midge (GM) resistance was evaluated in green house nursery at Phrae Rice Research Center during 2007-201. It was found that this promising line showed resistance (R) to high resistance (HR) to GM which collected from 5 areas, i.e., Mae Hong Son, Chiang Mai, Chiang Rai, Nan, and Phrae provinces. Furthermore, in 2012, the biotype of gall midge from 5 areas were studied and found that they were divided into two biotypes: 1) the gall midge collected from Mae Hong Son and Chiang Mai, which PRE01017-10-1-1-1 showed highly resistant (HR) score to GM, and 2) the gall midge collected from Chiang Rai, Nan and Phrae which PRE01017-10-1-1-1 showed resistant (R) score to GM. The mechanism of resistance in... |
