การลดความรุนแรงของโรคไหม้ของข้าวโดยการปลูกแบบหลายสายพันธุ์ในภาคเหนือตอนล่าง Thai Agricultural
Acharaporn Na Lampang Noenplab.
This study was carried out at Phitsanulok Rice Research Center during 2008-2010 aiming for minimizing rice blast severity by growing 2 rice lines differed in blast resistance to broaden rice genetics. In 2008, resistance screening was performed on 2 sets of blast resistant rice lines derived from KDML105 having different donors of resistance developed by Ubon Ratchathani Rice Research Center. Ten selected blast isolates were inoculated one at a time onto 21 day-old seedlings at 50,000 spores/ml and kept at 25 o C in the controlled room for 7 days before assessment. Since selection criteria were based on resistance to half of the tested isolates and an ideal pair should have similar maturity, therefore, none of the lines have been selected. In 2009, the...

สภาพฟ้าอากาศที่เปลี่ยนแปลง: ผลกระทบของอากาศหนาวเย็นต่อผลผลิตของข้าวในเขตภาคเหนือตอนล่าง Thai Agricultural
Acharaporn Na Lampang Noenplab.
Rice growing areas in the Lower North of Thailand has been severely affected by extreme climate change seen as cold injury in 2007 dry season. The total affected area was 621,176 rai (99,388 ha) resulted in a drastic loss of 2,749 million Baht ($US 89 million). Since it has been reported that the most sensitive stage to cool temperature is the young microspore stage, approximately 8.5-10 days before flowering, and the critical range of temperature for cold injury resulted in panicle sterility is 15-20 oC. This preliminary investigation firstly aimed to observe visible changes after exposing to cool temperatures. Secondly, to observe the relationship between low temperature and sterility. Thirdly, to measure a subsequent reduction in grain yield of rice cv....

This study was carried out in the continuous irrigated rice cropping system during 2011-2013 by 8 rice research centers and Bureau of Rice Research and Development. Disease assessments were also conducted in the farmers’ fields in 16 provinces responsible by participating offices in the Upper and Lower North, Central, East and South of Thailand. The main objective was to investigate the relationship between meteorological data and disease epidemics through field survey and carried out experiment on continuous rice cultivation by sowing popular rice variety every month. Three significant rice pathogens i.e. Blast, Bacterial leaf blight and Ragged stunt were collected for diversification study. Results revealed that there were disease epidemics in 19...

Objectives of this study were to estimate genetic parameters of number of born alive (NBA) in different parities and to examine the appropriateness of the 3 models. The genetic parameters in all models were evaluated. In model I, single-trait animal model, each parity was considered as a different trait. In model II, repeatability model, each trait of different paritys was measured repeatedly. In model I, multiple-trait model, each parity was treated as a different trait. The 6,375 records of NBA from sows that born between 2546 to 2552 were analysed. They were grew by private farms in the central part of Thailand. (Co)variance components and breeding value were estimated by Restricted Maximum Likelihood (REML) and Best Linear Unbiased Prediction (BLUP)...

Rice is the stable food of Thai people and also to be the first level among the agricultural commodities for export. In the recent year, most of the consumer give awareness to the safety of food. Moreover, this issue was taken to use as the trade barrier for import-export. This study have been conducted to investigate the possibility of Aflatoxin B1 and Ochratoxin A contamination in brown rice and white rice. Brown rice and white rice samples were collected from 5 markets with 5 samples of each kind per market in Bangkok in June 2009. ELISA technique was employed to use in this study for their rapid test of hundred samples. DOAAflatoxin ELISA test kit was used to detect Aflatoxin B1 whereas Ochratoxin A was detected in rice using ELISA test kit of Neogen,...

Study examines the economic efficiency in organic rice production in Chiang Mai, Chiang Rai, Yasothon, Surin and Phatthalung province. Data for the study was collected from 223 organic rice farmers in the 5 provinces. Production function analyses which incorporate the conventions test of economic and technical efficiencies were use as the analytical technique. Finding resealed that gained the economical return in term the ratio of net income over the production cost of 6.7, 4.3, 3.6, 2.3 and 1.2 in Surin, Chiang Mai, Chiang Rai, Phatthalung and Yasothon respectively. Further environmental effect was the factor is the most influencing farmer decision to change production cost rather than market price, marketing and outside supporting.

คุณลักษณะของเชื้อพันธุกรรมอ้อยพันธุ์ไทยและแนวทางการนำไปใช้ประโยชน์ Thai Agricultural
Amarawan Tippayawat; Werapon Ponragdee; Taksina Sansayawichai.
Thai sugarcane clones are continuously developed to obtain new varieties from old outstanding clones. Most of good parents still gave good progenies. However, a few varieties are widely popular. According to this reason, the features of the 95 clones from recommended varieties, elite clones and land race clones were studied to find out good guidelines to utilize them to improve yield and high sugar content of new sugarcane clones. Each sugarcane clone was planted in 1 row per 5 meter long, and distance between row was 1.4 meters (harvest 3 meters) during April 2011 to April 2012 at Thaphra site, Khon Kaen Field Crops Research Center. Agronomical and botanical traits were recorded in every stage until the harvest. The results showed that more than 50% of...

Remote Sensing - based Information and Insurance for Crops in Emerging Economics (RIICE) is a collaborative project between 3 organizations: the International Rice Research Institute (IRRI), SARMAP and the Rice Department of Thailand. The experiment was conducted during 2013 - 2015 in the areas under responsibility of Suphan Buri Rice Research Center and Nakhon Ratchasrima Rice Research Center. The satellite COSMO Skymed, stripmap type with 3-meter resolution and 40 x 40 kilometer-wide image, was used at Nakhon Ratchasrima, while the satellite COSMO Skymed, scansar type of 15-meter resolution and 100 x 100 kilometer-wide image, was used at Suphan Buri. The different fields survey was conducted to collect geographic coordinates, crop management by farmers,...

In wet season, rainfed area in Lower Northern of Thailand has has an abundance of soil and water availability which is suitable for growing a photoperiod-sensitive rice with high yield potential. However, favorite rice varieties often have low yield and are susceptible to rice pests. Breeding for high yield and resistance to disease and insect pests while maintaining good eating quality is, therefore, the major approaches in changing rice varieties for good qualities, increased yield and adequate consumption. A promising lines, PSL97060-17-CNT-1-2-1, was obtained from three-way cross between KLG88028-22-1-2-2 and F1 of SPR88096-17-3-2-2 and IR60 at Phitsanulok Rice Research Center.
