| Abstract: | He 50A is a new WA-type early cropping indica CMS line in rice,which is developed by crossing Jin 23A to a selected F4 plant of Zhong 9B//161-SB/Jin 23B through successive selection and backcrossing. It has characteristics of stable and complete male sterility ,perfect plant type ,medium growth duration,good flowering habit ,high stigma exposure rate and out-crossing rate, good grain quality and strong combining ability. Key techniques for propagation and cross breeding of He 50A was introduced. |
