Evaluations Of Cherry Tomato Variety Resources And Primary Studies On The Affect Factors Of Long-storability

In this research, twenty - four cherry tomato resources were used as materials,andel2 quantitative characteristics of the fruit were tested and analysed,which were divided into long-storability,the shape and structure factor, and the fruit quality factor. The studies on these characteristics gave some appropriate methods for quantificational testing in long-storability processing tomato fruit, and discussed genetic behaviors of these characteristics and relationships among them. Analysis methods included system cluster, gray relevancy, correlation analysis, and so on. Following results were obtained:1 Has carried on the system analysis to the cherry tomato resources target, finally indicated: The long-storability hereditary capacity, the hereditary change coefficient is biggest, the anticipated choice effect is best; the fruit pulp thick anticipated choice effect is worst. The long-storability and the shape structure character connected coefficient analysis indicated the long-storability and the ventricle width relations are closest. Long-storability and fruit quality factor the connected coefficient analysis indicated the long-storability and the PG content relations are closest2 In this research, twenty-four cherry tomato resources could be divided into six groups by clustering analysis: the first group were T1,T14,T16, the second group were T6,T8,T17,T20,T22,T24,T21andT23, the sixth group were T12, T13, the three were oval cherry tomato In which the first group of T1, T14, T16 as the long-storability good also the quality good cherry tomato material; the third group were T2,T9, the fourth group were T4,T10,T5 andT15,the fifth group were T3,T19,T18,T7,T11. The three were circular cherry tomato in which the third group o...
