| Abstract: | Yangfujing 7A,derived from the cross between Xu 9201A and Yangfujing 7 and its successive backcrosses,is a BT-type japonica CMS line developed by the Agricultural Institute of Riparian Region of Jiangsu Province.It shows good integrated characteristics,stable male sterility,good flowering habits,high out crossing rate,strong disease resistance,fine grain quality (reaching the 1st class of national standards for fine quality rice) and high combining ability.In 2012,it was technically identified in Jiangsu Province.Its F1 hybrid combination Tongyoujing1 (Yangfujing 7 A/R98),showing high yield and good grain quality,was registered and released to commercial production by Jiangsu Crop Variety Appraisal Committee in 2013. |
