Abstract
The gene locus Glu-1 controlling rice seed protein glutelin α5a and α5b subunits has been shown linked to the semidwarfing gene sd-1 on chromosome 1. The sd-1 gene linked to the shattering gene sh-2 with a recombination value of 13.7 %. To determine the location of Glu-1, sd-1 and sh-2 Ioci on chromosome 1, a crossing test was conducted using the semidwarf nearisogenic line SC-2 and tall Japanese cultivar Norin 29 as parents. Recombination values between Glu-1 and sd-1 Ioci, between Glu-1 and sh-2 Ioci, and between sd-1 and sh-2 Ioci were 17.1, 21.2 and 11.4 %, respectively. Based on these values, Glu-1, sd-1 and sh-2 Ioci were estimated to locate in this order on chromosome 1.
