HATRI 200 - AROMAPROMISING RICE VARIETY

SUMMARY
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 Kuming/SP6//4* Kuming. The same time has grown Hatri 200 in group A2 (on 95-100). Height 110-115cm and paniclelength 22-26cm. Compared to other lines, the number panile / hill average (11panicle. hill). The number of filling from 123.5. However on a number of fertile land, the number of seeds on panicle are also reaching 150.5 seeds. Weight of 1000 seeds reached 25.5g. Reviews on harvest index (HI), HATRI 200worth the relatively high HI, gaining 0.57.To confirm the presence or absence of fragrance in HATRI 200. A set of 8 lines was phenotyped using gas chromatographic separation to quantify 2AP content in milled rice samples. KOH tested and PCR method with two directives RM223 and FMU1-2 recorded to select some lines with the best fragrance followedProductivity of HATRI 200has great potential in the winter-spring season, but often for low productivity in the summer. The yield 8.13 tonnes/ha of winter-spring season and 5.40 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
Keywords: aroma, genetic, plant breeding, yield, low amylose, stable.
