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 OM7347 with KhowdawMali 105. The same time has grown 10 HATRI in Group A2 (on 95-100). Height 110-105cm and paniclelength 25-28cm. Compared to other lines, the number panile / hill average (11panicle ). The number of filling from 148.3. However on a number of fertile land, the number of seeds on cotton are also reaching 192.5 seeds. Weight of 1000 seeds reached 27, 8 g. Reviews on harvest index (HI), HATRI 10 worth the relatively high HI, gaining 0.58. Productivity of HATRI 10 has 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. HATRI 10 rice, soft materials (amylose special 20%), seed has the fragrance level 1. This is just like having wide adaptability, stable yield, should it be maintained quite long in production in the Mekong delta.
