Golden Rice 13A is a weak Indica CMS line with artificial wild-type sterile cytoplasm that is made by artificial protection (gold 23B × Bo B) and backcrossed with Bo A. The male sterile line has the characteristics of stable fertility, good plant type, strong combining ability, large spikelets, moderate grain density, moderate amylose content, soft consistency and low gelatinization temperature, good flowering habits and outcrossing, Breeding seed production is high, in October 2006 passed the Guangdong technical appraisal. The hybrid rice possessed the characteristics of weak photosensitivity, high yield, better quality, better cooked color in the late stage, and stronger cold resistance, of which, Jinyouyou 122, Jinyouyou 368 and Jinyouyou 998 were respectively cultivated in 2008, 2009 and 2010 Year passed the Guangdong Province species validation.
