Rice blast disease is the major disease in rainfed lowland area of Thailand. The causal fungus of this disease is Pyricularia grisea Sacc. Variation of this fungus was higher than other rice pathogens. This report used near isogenic lines (NILs) to detect the variation, pathothype and virulence spectrum of the fungus in Thailand during 2002 - 2005. Trap blast nurseries consisted of 9 Thai local cultivars and 18 NILs were conducted at Ubon Ratchathani Rice Research Center, Khon Kaen Rice Research Center, Phrae Rice Research Center, Phitsanulok Rice Research Center, and Phatthalung Rice Research Center. Single conidia was isolated from infected rice leaves. Virulence spectrum of blast populations were screened on 18 NILs. Two thousand four hundred seventy...

Most farmers in the Northeastern Thailand grow Khao Dawk Mali 105, a non-glutinous variety because of its premium cooking and eating quality and its aroma. However, KDML105 is susceptible to blast, brown planthopper and soil salinity. In order to maintain its yield stability, it is necessary to incorporate those above mentioned traits into KDML105 background. By using molecular markers to select for those plants carrying the target genes in each generation, it will help improving the selection efficiency in term of accuracy and time consumed. The experiment was conducted at Ubon Ratchathani Rice Research Center during 2007-2012 using the lines derived from the backcrossing program of KDML105; UBN03004 (IR77955-14-17*2/B.T) and UBN03007...

SSR molecular markers SSR are tandem arranged repeats of short DNA motifs (1-6 bp in length) distributed throughout the genome that frequently exhibit variation in the number of repeats at the locus of each rice variety. The SSR markers, therefore, are suitable for detecting polymorphisms between closely related genotypes of Thai local rice varieties from the National Rice Germplasm Bank. In this research, DNA fingerprinting was conducted using 8 Thai local rice varieties. i.e., Niaw Sanpahtawng (NSPT_GB), Khao Gaw Diaw (KGD_GB), Niaw Dam (ND_GB), Khao tah Haeng 17 (KTH17_GB), Jao’ Haw (JH_GB), Pin Gaew 56 (PG56_GB), Jek Chuey Gahb Khiaw (JCGK_GB), Sang Yod Pattalung (SYPL_GB), and 5 standard varieties, i.e., Khao Dawk Mali 105 (KDML105_GB, KDML105_C),...

Genetically modified (GM) insecticidal rice line, Bt63 (Shanyou63), has been developed in China and found unauthorized in processed rice products in many countries. This transgenic rice contains a copy of the synthetic DNA sequence with two genes: CryIA(b) and CryIA(c). These genes encode for the respective Bt toxins which is lethal to Lepidoptera. The aim of this study was to determine the contamination of Bt63 in non-labelled commercially available processed rice products from supermarkets. In this study, a real-time Polymerase Chain Reaction (PCR) was used to simultaneously determine the contamination of Bt63. The survey was conducted on a total of 21 and 42 non-labeled samples of processed rice products collected in the years 2011 and 2012,...

Currently, there are several reports on GM rice illegally available on market. To set up a defense measure in order to prevent GM contamination in Thai rice market, this activity was conducted by analyzing for CaMV 35S Promoter, NOS terminator and a transgene CryIA(b), which were carrying by the Bt63 rice. The Bt63 rice is an insect-resistant rice variety developed by the People Republic of China. The analyses were done by using a Real-Time PCR technique. DNA samples were extracted from rice products using a GeneScan extraction method and confirmed by a PCR using a primer pair KVM159/KVM160, which amplifies a rice species specific PLD gene encoding for an enzyme Phospholipase D. It was found that all samples could be amplified showing a PLD gene with a...
