| Abstract: | Jinke 1A,developed by crossing the selected F3 individuals of Gang 46B/Jin 23B to Jin 23 A and followed by successive backcrossing,is an indica WA-type CMS line in rice.It shows many good characteristics such as complete pollen abortion,stable male sterility,high stigma exertion rate(90%),high outcrossing rate and easiness for multiplication and hybrid seed production.It has a compact plant type with narrow and erect leaves,good restorability and good grain quality.It was technically identified in Hubei in September,2005.Its hybrid combination Keyou 8377(Jinke 1A/R8377) showed a high yielding potential and good grain quality,and was registered and released to commercial production by the National Crop Variety Appraisal Committee in September,2006. |
