Effects of tall alleles SD1-in and SD1-ja to the dwarfing allele sd1-d originating from 'Dee-geo-woo-gen' on yield and related traits on the genetic background of indica IR36 in rice.

ABSTRACT: sd1-d originating from 'Dee-geo-woo-gen' has been utilized to develop short-culmed indica varieties adaptable to higher fertilizer-application. Its tall alleles SD1-in and SD1-ja are harbored in indica and japonica subspecies, respectively. The sd1-d of indica IR36 was substituted with SD1-in or SD1-ja by recurrent backcrossing with IR36, and two tall isogenic lines ("5867-36" and "Koshi-36") were developed. IR36, 5867-36 and Koshi-36 were grown in a paddy field in three years, and yield and related traits were measured, the effects of SD1-in and SD1-ja on yielding ability and related characteristics were examined on the genetic background of IR 36. SD1-in decreased panicle number per m² b
