区域性试验 meaning in English

regional test

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
摘要利用1994和1995两年广东省杂交稻区域性试验资料以及1995和1996两年全国?型杂交晚稻区域性试验资料，通过t检验、变异系数和回归系数分别对特优524和对照种（汕优63 、汕优桂33 ）的丰产性、稳定性和适应性进行分析和比较，结果表明：特优524的丰产性、适应性均明显地优于对照种，而稳定性则次于汕优63 ，但好于汕优桂33 ，是一个较为理想的迟熟高产杂交稻新组合。
