High variation occurs due to climate changes includes low rainfall and uncertain distribution pattern. This affects rice production system. Farmers currently adjust their production system in order to minimize risks of crop losses. This study aims to develop the most suitable cultural practices and chemical fertilizer application for delayed transplanting crop. The adjusted production system to deal with the climate change includes a choice of varieties, cultural practices, water management, and nutrient management. The results from the farmers' interview at the beginning of the project indicated that most farmers faced the problem related to insufficient amount of water for the whole cropping season, late rainfall, dry spell or even drought problem. The...

DNA fingerprints are DNA banding patterns obtaining from DNA samples that have been undergone through molecular genetic processes. These DNA fingerprints can be used to identify the genetic relationships or differences among individuals. DNA fingerprints will be very useful for plant varietal protection in the future, especially for those economically important crops. Regarding to plant varietal protection, an information used to describe agronomic characteristics of a given plant variety should follow Mendelian rules and not be affected by environments. DNA fingerprints of 33 Thai recommended rice varieties were conducted by using 32 DNA markers. The DNA banding patterns at each locus were compared to allele standards that have been conducted from 17 rice...

ความสัมพันธ์ของฤทธิ์ต้านอนุมูลอิสระกับปริมาณ Tocopherol และ gamma aminobutyric acid (GABA) ในข้าวกล้องและข้าวกล้องงอก Thai Agricultural

Rice contains several kinds of bio-functional components. In this study, γ-aminobutyric acid (GABA) and Tocopherol, or Vitamin E were identified and their relationships to antioxidant activity using DPPH assay of both brown and pre germinated Thai rice varieties were studied. GABA are one of the two inhibitory neurotransmitters which make the neuron resistant to stimulation by excitatory neurotransmitters and inhibitor of some cancer cells activity whereas Tocopherol, or Vitamin E, which acts as antioxidant and improve blood cholesterol. Identification of GABA and Tocopherol in both brown and pre-germinated brown rice grown from different locations were conducted in eleven varieties, namely: Khao Dawk Mali 105, PTT1, CN1, RD31, Sang yod, RD6, Hom...

ความแตกต่างในความรุนแรงของเพลี้ยกระโดดสีน้ำตาลต่อการเข้าทำลายพันธุ์ข้าว Thai Agricultural
Jate Kotcharerk; Phamorn Pattawatang.
Evaluation of the ability of rice varieties in resistance to brown plant hopper was performed using seed box screen test. The brown plant hopers (BPH) were collected from rice paddy fields in Phitsanulok, Chainat, and Ang Thong Province. From cluster analysis at level 0.8, there were three different groups classified by the different level of rice plant damage after treated by the insects. The three different level of damage were graded by the ability in resistance to the BPH as resistance, moderately resistance and susceptible. Considering in biotype of the BPH, the results indicated that there were variety of BPH biotypes in each samples collected from the three different provinces. Mainly, the biotype 4 and 5 were indentified in these samples. However,...
