The same time has grown HATRI llNep in group Al (90-95 days). Height 105-110 cm and panicle length 24-27 cm. 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 land, the number of seeds on panicle are also reaching 120.5 seeds. Weight of 1000 seeds reached 25.5 g. Reviews on harvest index (HI), HATR1 11NEP the relatively high HI, gaining 0.57. To confinn the presence or absence of fragrance in HATRI llNep. HATRI llNep 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 amylase. The yield and component yield of HATRI UNEP has great potential in the winter-spring season, but often for low productivity in the summer. The yield 7.08 tonnes/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.
