| Rice Gall midge (Orseolia oryzae (Wood-Mason)) is a major problem in the upper Northern part, a glutinous rice line PRE04012-20-1-1-1 was derived from a single cross between Sahm Samai and PRE96011-SPT-1-2-2-1-1 since 2004. The farmer field trials had tested in 2011-2013. In wet season, high potential yield was 1,043 kg/rai while the average yield was 703 kg/rai which was non significant different from 710 kg/rai of RD14 and 704 kg/rai of SPT1. In dry season, the high potential yield was 916 kg/rai while the average yield of PRE04012-20-1-1-1 and SPT1 were 714 kg/rai, but lower than RD14 (759 kg/rai) by 6 percent. In addition, this line can produce maximum yield of 780 kg/rai at 20.4 kg N/rai. This line performed better gall midge resistance (R-MS in green... |
