title: Some induced dwarfing genes non-allelic to Dee-geo-woo-gen gene in rice, variety Tellakattera.
abstract: The allelic nature of five dwarfs (d6, d7, d8, d9 and d10), recovered in M2 after ethyl methanesulphonate treatment of a local rice variety Tellakattera, was studied in relation to the Dee-geo-woo-gen (DGWG) dwarfing gene. The behaviour of the different crosses of the dwarfs with DGWG in F1 and the segregation pattern in F2 clearly demonstrate that these induced dwarfs are non-allelic to the DGWG dwarfing gene. In view of the extensive use of this gene in developing most of the high yielding rice varieties, the new dwarfing genes of Tellakattera may be exploited as alternative sources, to avoid genetic vulnerability.
