Sticky seed watermelon (Citrullus lanatus (Thunb.) Matsum the Nakai sp.mucosospermus (Fursa, 1972)) originated in western Africa, watermelon (Citrullus lanatus sp.vulgaris var megalaspermus Lin et Chao) originated in China's northwest, which belong to different subspecies. 6 seed watermelon pure Department: black blockbuster 1, black blockbuster 2, black in the piece, a small black piece, D7, D3 and 5 sticky seed watermelon pure Department: S216, S215, D98, D82, D68 for materials, using incomplete diallel cross method of preparation of the 30 hybrid combinations studied hybrids between the subspecies main character combining ability and heritability of traits related to yield primary and secondary relationship and seedling wilt resistance, and the sticky seed watermelon S215 and S216 with black blockbuster 2, its hybrid offspring seeds nutrients. While taking advantage of D7 S216 and black small piece S215 formulated two combinations of six generations Pa, Pb, F1, F2, BC1Pa, BC1Pb study analyzed genetic rule sticky the Zizhong skin traits and single fruits and real weight, as well as single melon seed number of genetic models. The results show that: the general combining ability of a single melon seeds in the seed watermelon parents and 30 hybrid combinations single fruits and actual weight, the special melon seed weight with the force of difference between the 30 combinations impact is not significant. Single fruits and real weight, the melon seed weight, number of melon seeds and 30 seeds weight general combining ability and specific combining ability variance were: 96.71%, 98.01%, 62.78%, 80.39 and 3.29%, 1.99%, 37.22%, 19.61%. The the sticky seed watermelon D98 parental and seed watermelon D3 performed better in the general combining ability of major traits. 30 weight, 2 single melon seed melon seed weight, real weight of single fruits, melon seed number of broad-sense heritability and narrow sense heritability were: 94.89%, 58.57%, 55.86%, 56.28% and 76.28%, 57.40 %, 54.02%, 35.33%. The 3 seed traits related to yield primary and secondary relationship as follows: fruit number per plant gt; single melon seed weight gt; 30 seeds weight gt; single fruits and real weight gt; premature aging index gt; Nodes gt; number of melon seeds associate degrees: 0.4872,0.4370,0.4329,0.4159,0.4152,0.3832,0.3589. 4 seedling stage Inoculation results seedling stage anti wilt material is not purely for the test sticky seed watermelon seed watermelon in the D3 at the seedling stage resistance to fusarium disease performed better. The 5 sticky seeds watermelon S215 and S216 in the protein content is less than seed watermelon black large, the crude fat content is higher than the seed watermelon. The hybrids protein, crude fat and fatty acid content between the two parents. The 6 the sticky seed watermelon seed coat sticky sac traits belonging to a single recessive gene control. The the generations mean genetic model analysis that the two combinations of single fruits and real weight and the number of single melon seeds are a plus - dominant inheritance model additive - dominant - epistatic genetic model. Polygenic major gene mixed inheritance model analysis: D7 combination of single fruits and real weight and melon seeds quantitative trait belonging to two additive - dominant major additive gene the - dominant multi-gene model (E-2) and two dominant major gene additive - dominance polygenic mixed genetic model (E-6); quantitative traits of black small piece of fruits and actual weight of the combination of single and melon seeds belong to two additive - dominant - epistatic gene additive. dominant polygenes mixed inheritance model (E-1) and two peer additive primary additive gene - dominant multi-gene model (E-4). Look at the 7 major comprehensive observation Genetic effects in the breeding process D3 resistance to fusarium disease breeding and D98 to use sticky seed watermelon expand seed watermelon genetic material foundations are good breeding material.
