Abstract:
Abstract:Taking early-maturing watermelon variety ‘Jucheng Lyu Zhi Mei’as materials,the principal component was extracted in watermelon-related traits and counted contribution rates,and the eigenvectors were obtained to build the main component of a comprehensive model by the method of principal components analysis.Then it conducted watermelon yield-related traits a comprehensive evaluation and got the main ingredient to obtain comprehensive evaluation model,so gave the four cultivars reasonable score.The results showed that the principal component analysis made the judge to varieties on the concept of a number,which was a new method of watermelon yield traits evaluation.It may also provide a scientific basis for validation to promote the use of varieties.Comprehensive evaluation results showed that,the ‘JuCheng Lyu Zhi Mei’ was the best in four varieties.
