| Chiang Mai Rice Research Center has carried out a project on the early warning system for major rice pests in Chiang Mai since 2011. The project consisted of 3 activities; 1) Rice blast forecasting 2) Light trap counting and 3) Field survey for rice pests. Blast risk was indicated by BUS (Blast Unit of Severity) obtaining from the values calculated from the weather data on courtesy of Chiang Mai Meteorological Station. Results revealed a risk for rice blast epidemics at seedling, tillering, booting and flowering stages. These coincided with rice blast epidemics at some surveyed fields and farmer’s field epidemics recorded in 3 areas i.e. M.4 Sunttisuk, Doi Lo district, M.4 Sankhang, Sanpatong district and M.6 Sansai, Phrao district. Furthermore, insect... |

| Cultivated rice (Oryza sativa L.) is self-pollinating, with flowering traits that exclude crosspollination. Hybrid rice seed production is therefore limited by low outcrossing rate between parental lines. To improve outcrossing ability in cultivated rice, common wild rice (O. rufipogon Griff.) was used as a source for outcrossing traits and backcrossed to Suphanburi 1 (SPR1) cultivated rice (BC2). In this study, F5 progenies of the backcross (BC2F5) were grown and evaluated for flowering traits in comparison with SPR1 parent. At flowering, florets were collected to measure the length of anthers and pistil. The anthers of SPR1 averaged 2.32 mm and pistil 1.50 mm, in length. The F5 population ranged 2.40 to 3.93 mm in anther length (3% to 170% of SPR1) and... |

| SSSIVb gene, which is the group of Soluble Starch Synthase enzyme, concerns to synthesis amylopectin in the seed of rice. In this research, we will examine the process of mRNA splicing intron 6, 7, 8 and 9 of SSSIVb gene and observe the expression of gene in development of seed at 5, 10 and 15 days after flowering (DAF) in 5 varieties of the rice which are RD10, Chai Nat 1, Niew Phrae 1, San-pah-tawng 1 and Suphan Buri 60. All of those varieties have different quality of cooking. From the experimental, we found that Chai Nat 1 had splicing in 5 DAF rice seeds but no expression in 10 and 15 DAF rice seeds. In Suphan Buri 60 had splicing in 10 DAF rice seeds but no expression in 5 and 15 DAF rice seeds. And RD 10, Niew Phrae 1, San Pah Tawng 1 had splicing... |

| Elite line, IR57514-PMI-5-B-1-2 was bred at International Rice Research Institute (IRRI) in 1987. Then it has been selected at Phimai Rice Research Station. After that, yield trials were conducted under rainfed lowland condition in North and Northest Thailand. When grown in famer field under drought prone during 1996 - 1999, this line gaved the highest yield by average 542 kg/rai and inter-station yield trials during 2002 - 2014 it yielded by average 598 kg/rai which were 22 and 17% higher than KDML105 in the tested field conditions. The adventages of this line are drought resistance, submergence tolelance, resistant to rice blast disease and high adaptation to grow under rainfed condition. Therefore, it is suitable for reducing the risk from climate... |

| Eight improved clones of forage-cane were evaluated for biomass yield performance under irrigatedcondition at Kasetsart University, Kamphaeng Saen campus, Nakhon Pathom during 2011-2012. The study wasdesigned with randomized complete blocks design with 4 replications in 3 crop-cycles, newly planted, first-ratoon and second ratoon that harvested at 6, 4 and 4 month after planting/ratooning, respectively. Total fresh biomass yield from 3 crop-cycles was 40.47 ton/rai. The total yield of 3 crop-cycles varied between 27.44 and 46.46 ton/rai. High biomass yield obtained from the new clones 28-2113, 28-2114 and 28-1727 that were equal to 46.46, 44.86 and 42.96 ton/rai, respectively. Although, three new forage-cane clones had high potential of biomass yield.... |
