New cotton varieties for Thai farmers
DORAS Project initiated in 1991 a cotton-breeding program in Thailand. After six years of breeding, the first wave of new variety creations is now available. The varieties were obtained by transferring into an agronomically well-adapted Thai genetic base (SSR 60) characters which improve its economic potential (gossypol free, coloured lint) or its agronomic quality (okra leaf, frego bract). These are the following varieties: DORA 11 (frego bract, highly productive, good earliness), DORA 21 (glandless seed, productive with a good tolerance to shedding, good fiber quality). DORA 31 (okra leaf. frego bract and good technological trails), DORA 41 (brown coloured fiber). DORA 11 may be adopted by farmers in the next years. Assessment of the other genotypes still needs additional experiments. As far as seed production of glandless varieties. like DORA 2 1, is concerned, avoidance of genetic mixing demands well-coordinated procedure.
