Abstract: Using the regional trial data of Guangdong hybrid rice in 1994 and 1995 , and regional trial data of national late hybrid indica rice in 1995 and 1996, by t test, variation coefficient and regress coefficient, analysis and compare with the fertility character, steady character and adaptive character of Teyou 524 and ck (Shanyou 63, Shanyougui 33) , the result showed: It was obviously that the fertility character and adaptive character of Teyou 524 was better than ck ,but steady character was between Shanyou 63 and Shanyougui 33, it was a quite good lat-mature and high-yield new hybrid rice combination .
