Comprehensive evaluation for rice cultivar trials locations in Fujian Province

Based on results of Fujian provincal rice cultivar trials of late maturing early indica rice group in 2002 and late indica rice A group in 2003,14 rice locations were comprehensively evaluated using productive level,precision, distinguishing ability representation and validity. The results showed that productive levels in 14 locations were diverse, they represented different field productive levels in Fujian; trial precisions in 14 locations were high,the trial were all valid, so trial technique levels in 14 locations were high and it was propitious to assure scientific and verracious in examining and approving rice varity; Tong’an, Xinluo, Mingxi and Longhai seed breeding farm had high distinguishing ability;Shaowu and Minxi seed breeding farm, Nanping agricultural scientific graduate-school, Fujian rice and wheat graduate-school,Licheng and Shaxian seed breeding farm had high representation, and they were fit to distinguish varity which had large range adaptability, so they were fitting the double rice locations and breeding spot in Fujian. AMMI-Dj and GCV were used to estimate location distinguishing ability, and two methods were compared in the study.
