“…Few studies on genetic control of growth habit can be found in literature (Vallejo & Mosquera, 1998), however it is known that gene "Bush" is responsible for compact growth habit in this genus (Robinson et al, 1976). The reduction of internode results from a decrease C ucurbits play an important role in human nutrition mainly in tropical and subtropical regions (Glala et al, 2011). In Brazil, this plant is grown mainly in the Northeast region where it is used for human and animal nutrition (Aruah et al, 2012).…”

This study was performed to introduce the allele Bush of commercial cultivars with a bush growth habit into Cucurbita moschata accessions and select the best crossings for production potential and standard fruit shape “Menina Brasileira” through general combining ability (GCA) and specific combining ability (SCA). To determine GCA and SCA, a partial diallel analysis was performed. The parental group (group I) consisted of two cultivars containing the dwarfism bush gene, and the second group (Group II), formed by five accessions of UFV Vegetable Germplasm Bank, with high production potential and fruit shape “Menina Brasileira”. We evaluated: productivity (PROD), fruit shape (FORM), growth rate until the 50th day after transplanting (CRESC), and length of the main stem on the 50th day (COMP). Significant differences were noticed for CRESC and COMP only between GCA of parents belonging to group I, in which Zapallo stood out. For PROD and FORM, diallel analysis proved to be efficient in studying GCA effects. Cultivar Piramoita (group I) and accessions BGH-4360 and BGH-5253 (group II) showed positive values for GCA, suggesting that these parents possess a higher frequency of favorable alleles for these two traits. Significance in SCA effects was also verified, highlighting the crossing Piramoita x BGH-4360, for PROD, indicating that this combination is the most promising for breeding purposes.

Ten melon accessions including eight resistant lines involving one snapmelon line (Cucumismelo var. momordica) and two susceptible lines with one genetic male sterile line were crossed to generate 45 F1?s through half-diallel design. These genotypes were evaluated for yield, quality and disease resistance traits in randomized block design with three replication. Pooled ANOVA for experimental design revealed significant mean squares due to environments except for ?-carotene and TSS of juice and, treatment ? environment except for fruit shape index and TSS of juice. The GCA estimates showed that parents Punjab Sunehri was a good combiner for seed cavity area (-8.80), flesh thickness (0.12), rind thickness (0.42), firmness (0.61), dry matter (1.02) and ? carotene (0.80) while SM-2012-12 for fruit yield (4.74), number of fruits vine-1(3.43), average fruit weight (0.06) and fusarium wilt incidence (-0.51) whereas, KP4HM-15 was good for average fruit weight (0.01), days tofirst fruit ripening (-2.31), TSS (1.21), pH (0.13), titrable acidity (-3.13), ascorbic acid content (5.89) and ?-carotene (0.06). The heterobeltosis ranged from -87.2 to 927.08% for the yield and quality traits whereas for fusarium wilt incidence has -100 to 69.23%.The study offers an opportunity for transferring fusarium wilt incidence into superior horticultural genotype. Hybrids KP4HM-15 ? Kajri Sel. 1, Kajri Sel.1 ? MM-202 and MM-314 ? KP4HM-15 were identified as promising on the basis of phenotypic performance, SCA effects and resistance to fusarium wilt disease. These hybrids can be evaluated further at multilocation to assess their suitability for commercial release.
