Seed drying is one of the most important processes of seed production in rice. The purpose for reduce seed moisture without any effects on seed quality. The continuous-flow drier need higher temperature for increased drying rate was used in this experiment. In2008, Five Experiments were conducted to find out the effected of temperature on quality under different levels of temperature including 45, 50, 55 45 fallowed by 50 and 50 fallowed by 55°c compared with sun drying method. In2009, study in two experiments. First experiment 3 levels of temperature including 45, 50, 55°c compared with sun drying and another 45 fallowed by 50 and 50 fallow by 55°c compared with sun drying. The suitable temperature for seed drying was 50 fallowed by 55°c without affected...

Whitebacked Planthopper (WBPH), Sogatella furcifera (Horvath) has been a major pest in irrigated rice growing areas of Chiang Rai province since 2003. Light trap, an effective tool for monitoring the outbreaks of WBPH was conducted in hot spot areas. A light trap was set in Chiang Rai Rice Research Center while surveying in farmers’ fields in Chiang Rai province were investigated during January 2009 to December 2010. The number of WBPH caught from light trap was counted everyday throughout the year. The results showed that light trap could collect a large number of WBPH. The peak of WBPH in light trap was 9,703 hoppers/trap/month which related to the WBPH outbreak in farmers’ fields.

Study on effect of environment on four rice planting durations (January, April, July and October) and four rice varieties (PTT1, PSL2, RD31 and RD41) was conducted at Ratchaburi Rice Research Center in 2011. The experimental design was split plot in RCB with three replications. Varietal characteristics, yield, yield component and meteorological data were recorded. PTT1 variety showed the longest maturity (128 days). Rice planting in April showed higher yield (808 kg/rai) than that planting in other durations. In addition, planting in April also showed the highest panicle length, number of filled seeds/panicle and 1,000 seed weight. The longest harvesting period (123 days) and lowest yield (510 kg/rai) was found in October planting. This could be...

การใช้ข้อมูล RADARSAT-1 SAR (standard mode) เพื่อทำแผนที่ แสดงพื้นที่ปลูกข้าวในภาคตะวันออกเฉียงเหนือ Thai Agricultural
Roengsak Katawatin; Panath Jermthaisong.
This research was conducted to investigate performance of using RADARSAT-1 SAR (standard mode)to map areas of the in-season rice cropping in the northeast region, in each particular year. Three sets of the radar data acquired on different dates, i.e., 4th July, 14th September, and 25th October 2006, were used. The MaximumLikelihood classifier was applied to classify these data based on 2 classification schemes. The scheme #1 included4 classes. Rice cropping areas were divided into 2 classes (Classes 1 and 2) representing 2 major cropping patterns.Class 1 was the areas of rice crop grown around June and harvested after last week of October. Class 2 was the areas of rice crop grown around June and harvested before last week of October. Other classes were...

Rice cropping system in irrigated area are rice-rice continuous cultivation. Farmers try to grow rice more than 2 crops/year. Nowadays there are no break even data. The aim of this research to compare economic data between 2 crops/year and 3 crops/year rice cropping system. Experiments were conducted in farmer’s field at Lumlukka district Pathum Thani province in 2011. There were 3 experiments : using the same variety, changed variety every season and changed variety every season with short duration rice variety in the rice cropping system. Each experiment consisted of 2 treatment: 2 crops/year and 3 crops/year rice cropping system. The result shown that 2 crops/year rice cropping system gave lower total yield and income than growing rice 3 crops/year...

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...

Irrigated paddy fields are the rice growing areas having high yield potential.Two significant factors enhancing high yield are the well-adapted variety and good in rice production management. PSL05101-93-1-32 is a promising rice line derived from the 3-way cross of PSL00508-3-1-1-4/IR66738-118-1-2//IR67966-188-2-2-1 in 2005. It had as high yield as 965 kg/rai (6.03t/ha).The average grain yield was 730 kg/rai which was greater than PSL2, CNT1 and RD47 by 14, 13 and 7%, respectively. The maturity was 115 days after sowing by transplanting method. Plant height was 83-90 cm. This promising line is a non-glutinous long grain rice having straw-color husk.

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...

Brassinosteroids are the plant hormone reported to alleviate heat stress. This study investigated the response of rice (Oryza sativa L.cv. Pathum Thani 1) to 24-epibrassinolide (EBR) or 7,8-dihydro-8-20-hydroxyecdysone (DHECD) under high temperature by examine photosynthesis performance and yield. The results show that foliar application of 0.01 μM EBR and 0.1 μM DHECD on V7 vegetative growth could increase the photosynthetic efficiency under 40/30 ºC (day/night temperature). In field growth experiment, the application of those brassinosteroids concentrations on V7 growth stage could increase seed setting in all panicle part and number of normal seeds per particle. The results indicated that EBR and DHECD alleviated heat stress of rice ‘Pathum Thani 1’ by...
