采用 Eberhart 和 Russell 的方法,对24个国内外甘蔗品种在福建蔗区的七个生态环境的6个主要经济性状表现进行稳定性分析。根据不同地点的平均表现,回归系数和回归离差,把品种划分为不同的适应类型。分析结果表明,福引79-8是对所有环境适应良好的高产高糖早熟品种;福引79-9表现出对良好环境的特殊适应,是个产量潜力高的中熟高糖品种;这两个品种推广后,预期可以取得显著的经济效果。福引82-17被发现为中熟高产高糖的中细茎品种,具有对良好环境的特殊适应;福引82-41被认为是普遍适应的早熟高产高糖品种;这两个品种尚待进一步扩大表证示范,再行确定其推广价值。福引79-11和福引79-7属于低产稳定型品种。研究表明,稳定性分析是评价甘蔗品种丰产性和适应性的有效手段。事实证明,本文的理论分析和田间实地鉴定的结果是高度一致的。
Using Eberhart and Russell methods, the stability analysis of six main economic traits of 24 domestic and international sugar cane varieties in seven ecological regions of sugarcane sugarcane area in China was conducted. According to the average performance of different locations, regression coefficients and regression deviations, the varieties are divided into different types of adaptation. The results showed that Fuyou 79-8 was a high-yield and high-sugar premature variety with good adaptability to all environments. Fuyin 79-9 showed a special adaptation to the good environment and was a middle-maturing high-sugar variety with high yield potential. The promotion of these two varieties After the expected significant economic results can be achieved. Fuyou 82-17 was found to be a medium and thin stem cultivar with high yield and high sugar content in medium and high yield, with special adaptation to the good environment. Fuyou 82-41 was considered as a premature and high yielding high-sugar variety, which was widely accepted. The two varieties have yet to be further expanded Table demonstration, and then determine its promotional value. Fukui 79-11 and Fukui 79-7 are low-yielding stable varieties. Studies have shown that stability analysis is an effective measure to evaluate the high yield and adaptability of sugarcane varieties. Facts have proved that the theoretical analysis of this article and field field identification results are highly consistent.
