Abstract
HATRI 11 Nep - A PROMISING AROMA STICKY RICE VARIETY
The new advances are applied to production, especially by the method of molecular indicators in collaboration with by improved method are made to the same breeder together many desirable genes from Nep ThaiLan / OM7898. The same time has grown HATRI 11Nep in group A1(90-95 days ). Height 105-110cm and paniclelength 24-27cm. Compared to other lines , the number panile / hill average (10-15 panicle / hill ). The number of filling from 110. However on a number of fertile pland, the number of seeds on panicle are also reaching 120.5 seeds. 1,000-grain weight (g) is 25.5g. Reviews on harvest index (HI), HATRI 11NẾP the relatively high HI, gaining 0.57.To confirm the presence or absence of fragrance inHATRI 11Nep. HATRI 11 Nep was phenotyped using gas chromatographic separation to quantify 2AP content in milled rice samples. KOH tested and PCR method with two directives wx and FMU1-2 recorded to select some lines with the best fragrance and amylose The Yield and component yield of HATRI 11NEP has great potential in the winter-spring season, but often for low productivity in the summer. The yield 7.08tonnes/ha of winter-spring season and 5.4 ton/ha in wet season. This is just like having wide adaptability, stable yield, should it be maintained quite long in production in the Mekong delta. Detail
