摘要:
根据福建省2002年早籼迟熟组和2003年晚籼A组两组区试结果,从试点生产水平、精度、分辨力、代表性和有效性等 个方面对福建省14个水稻区试点进行初步的综合评价研究.结果表明,14个区试点生产水平有高有低,代表着不同的大田生产水平;14个区试点的试验精度较高,试验均有效,说明试点的试验技术水平均较高,有利于保证我省水稻品种审定的科学性与准确性;同安场、新罗场、明溪场、龙海场等4个试点具有较强的品种分辨力;邵武场、明溪场、南平所、省稻麦所、荔城场、沙县场等6个试点普遍代表性高,适于鉴别具有广泛适应性的品种,是我省理想的双季水稻区试点和育种点.同时,用主效可加互作可乘模型法和变异系数法分别对试点的分辨力进行估算,并对两种估算方法进行比较分析.
Abstract:
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.
