This study aims to develop a new evaluation technique for Northern Corn Leaf Blight (NCLB) resistance in maize under greenhouse condition. Ki48/Ki47 F2 (160 lines) and 2 commercial verities (Hi-Brix3 and Insee2) were evaluated. For this technique 10-14 day old seedlings (4-5 leaves) were sprayed with ACIL1 spore suspension (104spores/ml.) for infection. The results of this technique correlated with the results from the common technique under field condition which used 21-25 days old seedlings (6-7 leaves) (correlation value = 0.658). This evaluation technique was used to assist in QTL mapping of NCLB resistance. Population of Ki48/Ki47 F2 (160 lines) were analyzed for QTL mapping by using Simple Sequence Repeats (SSR) markers. It was found that major parental polymorphism located on chromosome 5 and chromosome 8. When Single QTL analysis was performed SSR marker UMC1365 could clearly indentified qualitative trait loci on chromosome 5 and SSR markers UMC1095 UMC1268 and UMC2356 could clearly indentified qualitative trait loci on chromosome 8.

The objectives of this research were to study the effect of temperature on the roasted of paddy Sungyod Phatthalung rice with moisture content up to 12 percentage for popped rice production. Nutritional values including protein fat ash moisture content antioxidant activity and anthocyanin compound were studies. The temperatures used in roasting popped rice were three levels of 200 220 and 240 degrees Celsius. The result showed that all three temperature levels does not different effected to amount of protein fat ash and moisture content in popped rice. It was not statistically significant difference (p<0.05. Whereas the amount of anthocyanin compound and antioxidant activity decreased as the temperature increased. Temperature of 200 degree Celsius had the highest of anthocyanin and antioxidant activity showed 2.73 and 76.95 percentage respectively. It was statistically significant difference (p>0.05). The nutritional values in popped rice were lower than start paddy rice. The experiment showed that temperature was effected to reduced of nutritional values. Temperature range of studied indicated minimum decrease nutrition values of anthocyanin and antioxidant activity for the roasted popped rice was 200 degree Celsius.

This study aims to study the process of producing brown rice by housewives group who produced brown rice as otop product from Narathiwat Province. They designed and developed brown rice machine of PNU III. The machine were formed from a peeling machine fan for husk peeling sorted out rice and paddy machine paddy vascular system and wipe machine. They were formed as brown rice machine and given to housewives for producing brown rice as local product called otop in Narathiwat province. They brought Kradangga seed rice that exist in Narathiwat and exposed them to the sun up to 13-15 percent high then they were milled. From the experiment the study found that the distinction of rubber speed has caused the machine producing the brown rice with 93 kilograms per hour by using 3 HP motor energy. From the experiment it can be concluded that brown rice machine of PNU III has the quality and it is appropriate and good for increasing the product quantity to the housewives group

FAO reported in year 2008 world paddy production more than 40 countries and about 60 million tones of rice straw were produced in Thailand. For most farmers use an easy method for land clearing by straw burning in open area. Greenhouse gases such as carbon dioxide(CO2) emissions from paddy field burning to atmosphere is causes of global warming problem. This project aimed to utilize agricultural waste from rice field to be cheap biomass energy was started in 2009 at Nhongjork area. The waste was mixed with molasses and kaolin in ratio of rice straw : molasses : kaolin as 80:10:10 by weights. A size of rice straw fuel pellet was 1.54 cm. diameter and 2 cm. height. The calorific value of the rice straw pellet was tested by using Gallekamp Autobomb instrument by ASTM(American Society of Testing and Materials) standard. The results of testing found : CO2 emission from rice straw fuel pellets as half of burning in open area (by weight). Cost of energy for cooking by using Bio-fuel pellets only 7 Baht( 0.25 US $) and half price by comparing with LPG. The useful of rice straw Bio-fuel pellet is one of a cheap biomass energy for household and small manufacturers.

Gac fruit healthy fruit contains many antioxidants such as beta-carotene lycopene. Traditional process by boil reduces antioxidants. The purpose of this study is to process gac juice mixed passion fruit juice by microwave. The optimum formulation from consumer tests were done with 50 juice preferred consumer show that the average like is 3.90 point (5 point). The study used the 3X2 factorial in CRD with 600 700 and 800 watts and at 45 and 55 sec. Analyzed color amount of beta-carotene lycopene pH and microorganisms showed that 700 watts at 45 sec. gave the highest level of beta-carotene contents at 38.11 ?g/g. The comparison between the gac juice mixed passion fruit juice through boiled process and the gac juice mixed passion fruit juice through microwave process was investigated. The content of beta-carotene and lycopene of juice through microwave process was than 2.43 and 1.59 times respectively.
