Combining ability analysis was conducted to understand the nature of gene action of quantitative traits and to identify promising parents for breeding programme in muskmelon. Six female and five male parents were crossed in line x tester mating fashion to produce thirty F 1 s and were grown in a randomized complete block design with three replications. Analysis of variance showed high magnitude of GCA over SCA variance indicating predominance of additive gene effects for all the traits. RM 43 and IIHR122 were the best general combiner for most of the quantitative traits. Strong phenotypic correlation between GCA and parent per se performance for all traits except for number of primary branches per vine and fruit yield per vine indicated the possibility of selection of traits at the level of parents. Hybrids ms-1 x IIHR 616, RM 43 x IIHR 718 and RM 43 x IIHR 121 out yielded commercial check NS 910 with significantly larger fruits, significantly more sweeter and earlier in picking could be commercially viable for hybrid seed production as they involved male sterile (ms-1) and monoecious (RM 43) lines as female parent.

Journal of Horticultural Science, 2016
The parent Hara Madhu in E1, AMM-01-18 and AMM-02 -26 in E2 and AMM-01-18, AMM-02-26 and Hara Madhu on pooled basis exhibited positive and significant GCA effects for fruit yield per plant. Thus these three parents appeared to be good general combiners for fruit yield. Out of these parents AMM-01-18 had a good combining ability for fruit yield per plant, number of primary branches, number of fruits per plant, fruit weight, moisture content, total soluble solids, acidity and total soluble sugars on pooled basis. Specific combining ability effects for fruit yield and yield attributing traits revealed significant and positive SCA effects in fourteen crosses for number of primary branches per plant, nine for fruit length, twelve for fruit girth, ten for fruits per plant, eleven for fruit weight, nine for fruit yield per plant, eleven for flesh thickness, nine for moisture content, twenty for total soluble solids, twenty for acidity and fifteen for total soluble sugars data in the desire...
The present investigation was carried out at Vegetable Experimental Field, Division of Vegetable Science, SKUAST-Kashmir Shalimar during kharif 2021-22. The twelve parents of muskmelon along with their sixty-six crosses were evaluated for maturity, yield attributing and quality traits for identifying genotypes with high yielding ability and better quality. The result revealed that significant variations were found among the genotypes for the traits studied. The maximum performance for yield per plant and per hectare was observed in parent SKAU-MM-701 (4.73 kg/plant, 210.20 q/ha) followed by SKAU-MM-705 (4.64 kg/plant, 206.20 q/ha) and SKAU-MM-711 (4.46 kg/plant, 198.35 q/ha). Similarly maximum yield in crosses was observed in SKAU-MM-701 × SKAU-MM-702 (5.35 kg /plant, 237.90 q/ha) followed by SKAU-MM-701 × SKAU-MM-712 (5.31 kg/plant, 235.97 q/ha) and SKAU-MM-701 × SKAU-MM-708 (5.28 kg/plant, 234.78 q/ha). For quality traits maximum TSS content was observed in parents SKAU-MM-706 (10.5˚B) followed by SKAU-MM-701 (9.4˚B) and in crosses (SKAU-MM-701 × SKAU-MM-702 (12.2˚B) followed by SKAU-MM-702 × SKAU-MM-706 (11.9˚B). Thus overall evaluation of muskmelon parents and crosses showed that significant variation was present thereby indicating scope of improvement of this material through various breeding methods.
GENERATION MEAN ANALYSIS OF HORTICULTURAL TRAITS IN MUSKMELON (CUCUMIS MELO L
A six generation mean analysis study was carried determine the types and magnitude of gene effects for earliness, vine architectural, yield and its components in four muskmelon crosses viz., Punjab Sunehri x IIHR 122, RM 43 x IIHR 121, IIHR 681 x IIHR 121 and IIHR 681 x IIHR 122. A simple additive/dominance model was adequate as determined from the non-significance of all the scales for days to anthesis in the cross RM 43 x IIHR 121, days to first fruit harvest in the cross Punjab Sunehri x IIHR 122 and number of fruits per vine in the cross IIHR 681 x IIHR 122. For vine length, number of fruits per vine and average fruit weight in all crosses significance of one or more scaling test implied the presence of non-allelic interactions. Some gene effects cancelled due to simultaneous presence of positive and negative components for most of the traits indicated that negative alleles dispersed in the parents of the crosses for the inheritance of the traits. Therefore, selection for such traits should be done in later generation such that the desired recombinants become available in the population. Simple biparental recurrent selection would prove useful in obtaining more unique and desirable alleles, since additive, non-additive and interaction effects could able to locate further variability and effective selection of lines is possible.

The success of any breeding programs depends on the parents chosen. Breeders select parents with high mean values as an added benefit for crossing programmes. The present investigation was carried out to evaluate the performance of muskmelon genotypes for growth and earliness attributes. Muskmelon (Cucumis melo L.) is one of the most well-known desert vegetables, belong to the Cucurbitaceae family. Thirty-three germplasm lines were collected from different regions of India. The experiment was conducted at Puthur village, Salem district, and evaluated under Randomised Block Design with three replications during February to May 2022. The findings indicate that the genotypes CM 2, CM 16, CM 11, CM 19, CM 7, CM 13 and CM 22 reported as elite genotypes were exhibited higher values for different traits like days to first female flower opening, first female flowering node, number of vines per plant, vine length (cm), sex ratio and days to first fruit harvest. As a result, the above mentioned seven genotypes are used in the hybridization programme, could be exploited to develop elite cultivars with maximum growth and earlier in flowering and harvest.

The success of most crop improvement program largely depends on the understanding of relationship among characters and magnitude of this relation help to breeder to determine the selection criteria for breeding program. An investigation was carried out to assess the character association and path analysis for sixteen quantitative traits in F 2 segregating generation of Haramadhu × MS-78 cross. Association studies revealed that, six out of sixteen traits exhibited highly significant positive correlation with fruit yield per vine. However, the traits average fruit weight (0.721), number of fruits per vine (0.569), fruit length (0.340), fruit width (0.272), fruit shape index (0.231) and TSS (0.142) were found to possess significant association in desirable direction with fruit yield per vine at phenotypic level. Path analysis studies revealed that average fruit weight exhibited the highest positive direct effect (0.756) on fruit yield per vine followed by number of fruits per vine (0.609), fruit shape index (0.292), fruit width (0.135), sex ratio (0.011), TSS (0.019) and seed cavity width (0.009) showed true relationship by establishing significant positive association and direct effect on fruit yield per vine.
Genetic Analysis in Muskmelon (Cucumis melo L.)
Journal of Horticultural Sciences, 2016
Fifty genotypes of muskmelon ( Cucumis melo L.) were evaluated for variability, correlation, path analysis and divergence for yield and its contributing characters. Analysis of variance showed significant variation for all the characters, indicating presence of sufficient variability in the material studied. Genotypic correlations were higher than those of their respective phenotypic correlation coefficients in majority of the cases suggesting, that, genotypic correlations were stronger, reliable and free from environmental influences. Path analysis based on genotypic association revealed that number of fruits per plant and moisture percentage was the main yieldattributing characters in fruit yield of muskmelon. Total soluble solids exhibited positive direct effect on fruit yield per plant. Thus, number of fruits per plant, moisture percentage and total soluble solids may be given more weightage for an effective selection to improve fruit yield in muskmelon. On the basis of relative...
