General combining ability and special with the force of the parental and hybrid generation of a variety of traits, heritability analysis and evaluation of the parents, to select excellent pro-this, screening excellent combination, and thus the flavor quality, yield, etc. to identify presence of advantage F1, parent selection and combination of optional high yield and quality breeding of cantaloupe basis and learn in order to be able to fully take advantage of the potential of existing varieties resources between hybrid heterosis breeding quality, high-yielding varieties. Through 12 of the the six cantaloupe parents (M1 ~ M6) and 15 hybrid combinations fruit characteristics (fruit weight, fruit length, fruit diameter, flesh thickness, seed cavity diameter, heart sugar side sugar, soluble sugar, organic acid, protein, proline, vitamin C) general combining ability and specific combining ability analysis, the results show that there is no real genetic differences between fruit diameter, while sugar, protein genotypes of these three traits in combination; parent M4 performed well in the majority of fruit quality characteristics and M5 to elect quality F1 hybridization with other species; combination M5 × M6, M2 × M6 showed a distinct advantage in terms of quality and yield, M4 × M6, M1 × M2 showed a significant advantage in terms of quality, M4 × M5, M2 × M4 showed a distinct advantage in the production. Fruit weight, seed cavity diameter, the heart of sugar, soluble sugars and organic acids generalized heritability in 65.00%, less affected by the environment, in breeding should be selected in early generations; the remaining six broad sense heritability of traits magnitude 40.33% to 65.00%. Additive effects of traits (fruit weight, heart sugar, soluble sugars, organic acids, fruit longitudinal diameter, proline, vitamin C), to focus on the early selection; traits (mainly pulp non-additive effects thickness) should pay attention to the combination of optional. In this paper, cantaloupe soluble sugar content and other traits gray correlation analysis to try to identify the impact of various traits of quality and mutual relations, and provide the scientific basis for the breeding of new varieties. The calculation shows that each trait and the association of the soluble sugar content is as follows: edge Sugar gt; heart Sugar gt; the fruit diameter gt; flesh thickness gt; fruit longitudinal diameter gt; species of cavity diameter gt; proline gt; fruit weight gt ; vitamin C gt; Protein gt; organic acids. Related degree edge sugar heart candy, fruit diameter, flesh thickness, fruit length and soluble sugar content, soluble sugar content is more important. Which is the side sugar and heart sugar, soluble sugar content. During cantaloupe strain selection and development of cultivation techniques measures should be based on these two factors, the main study factors simultaneously integrated the other traits best choice, so as to achieve the purpose of quality and high yield. The innovation of this test is that, mostly just twelve indicators based on the evaluation of the pros and cons of cantaloupe. The test through the choice of six cantaloupe inbreds and optional use of hybrid combinations, through genetic analysis to determine the genetic characteristics and performance of the cantaloupe quality indicators, to identify superior hybrid combinations; through gray correlation degree and to find the quality formation of the quality factors that play a leading role in the process, so that breeders are easier to grasp and applications, thus improving the quality of the breeding.
