摘要:

采用品种和盐碱程度二因素完全随机试验设计,利用AMMI模型分析了5份耐盐碱水稻品种(龙稻16、13G028、13G030、13G040、长白9)垩白粒率和垩白度的稳定性,以期为苏打盐碱地水稻外观品质改良提供科学依据。结果表明,品种间垩白粒率和垩白度的稳定性不同,环境对垩白性状的影响也不同;垩白性状的总变异呈基因型(G)>环境(E)>基因型×环境(G×E),垩白粒率和垩白度PCA1、PCA2和PCA3平方和分别累计解释基因型×盐碱互作平方和的99.65%和99.80%;参试材料在不同盐碱梯度下垩白粒率和垩白度的稳定性以龙稻16最强,其次为13G030,再次为13G028和长白9,13G040的稳定性最差。

Abstract:

In order to provide the scientific basis for the improvement of appearance quality of rice in sodic soil, AMMI model was used to study the stability of chalky rice rate and chalkiness degree with 5 saline-alkali tolerance rice varieties(Longdao 16, 13G028, 13G030, 13G040, Changbai 9) as materials. The results showed that the stability of chalky rice rate and chalkiness degree were different in different varieties, and the effects of environment on chalkiness character was different. The effects on the total variation of chalkiness character was in the order of genotype(G)>environment (E)>G×E. Quadratic sum of PCA1, PCA2 and PCA3 of chalky rice rate and chalkiness degree explained 99.65% and 99.80% of the total variance quadratic sum respectively. The variety stability of Longdao 16 was the best in different saline-alkali environment, 13G030 was the second, followed by 13G028 and Changbai 9, 13G040 was the worst.
