Registration of ‘Adair’ Rice

Registration of Five Induced Semidwarf Mutants of Rice

“…GP‐89, PI 632952) in April 2002. The mutants were induced in four tall Arkansas rice cultivars, Kaybonnet (KBNT) (Gravois et al, 1995), LaGrue (LGRU) (Moldenhauer et al, 1994), Adair (ADAR) (Gravois et al, 1994), and Katy (KATY) (Moldenhauer et al, 1990), to obtain quickly semidwarfism in adapted germplasm. These mutants, which have height reductions from 18 to 24% of their tall parents, provide breeding sources of semidwarfism, nonallelic to the worldwide semidwarfing gene sd 1, in tropical japonica germplasm adapted to the southern USA and similar climatic areas.…”

Registration of Six Semidwarf Mutants of Rice

“…GP‐85, PI 632281), in March 1999. The mutants were induced at Stuttgart, AR, in four tall Arkansas rice cultivars, Kaybonnet (KBNT) (Gravois et al, 1995), LaGrue (LGRU) (Moldenhauer et al, 1994), Adair (ADAR) (Gravois et al, 1994), and Orion (ORIN) (Moldenhauer et al, 1992), to obtain semidwarfism in adapted germplasm quickly. These mutants, which have height reductions from 10 to 26% of their tall parents, provide breeding sources of semidwarfism nonallelic to the worldwide semidwarfing gene sd 1, in tropical japonica germplasm adapted to the southern USA and similar climatic areas.…”
