Muskmelons ( C. melo ) are important crops grown throughout the world. The United States ranked seventh after China, Turkey, Iran, Egypt, India, and Kazakhstan in 2014, with total production of 7.7 × 10 5 metric tons ( FAO, 2017 ; USDA-NASS, 2016

Organoleptic evaluations of shrink film-wrapped and nonwrapped musk-melon (Cucumis melo L. var. reticulates cv.. TAM Uvalde) fruit were conducted to determine changes in flavor and taste during refrigerated storage. Ripe green and yellow `TAM Uvalde' muskmelons, shrink film-wrapped in 12.7-μm high-density polyethylene film, were compared to nonwrapped melons during 21 days of storage at 4C and 90% to 95% RH. After 21 days of storage, both yellow and green shrink-wrapped melons had better appearance, less surface mold, and less vein tract browning than nonwrapped melons. However, the flavor and taste of shrink-wrapped fruit were significantly inferior to those of nonwrapped melons. Green-wrapped melons were rated poorer in taste and flavor than yellow-wrapped and nonwrapped melons after 14 days of storage. These results indicate that shrink-wrapping may enhance undesirable flavor changes in muskmelon during storage.

Windbreaks can increase crop growth and improve crop quality. The effects of shelter on vegetable production varies with crop, location, and farming practices. While the advantages of minimizing wind stress on vegetable production is well-known, little research documents the specific response of vegetables to microclimate modification through the use of shelterbelts.
During the summer, 1991, a preliminary experiment was conducted on the effects of tree windbreaks (shelterbelts) on muskmelon plant growth, yield, and fruit quality. A split-plot design was used with shelter and exposed areas as main treatments with 3 replications. Subtreatments were 7 combinations of anti-transpirant and time of application. Leaf growth was measured 4 and 6 weeks after planting. Muskmelon fruit were harvested over a 6 week period at 2 day intervals. Muskmelon yield, fruit and cavity diameter, fruit color, and total sugar content were obtained.
The use of anti-transpirant did not significantly affect total yield, fruit or cavity diameter, total sugar content, or early leaf growth. The effect of shelter varied with the measured variable.

A cold-germinable (CG) line of muskmelon (Cucumis melo L.) derived from PI 126156 was crossed to a noncold-germinable (NCG) line derived from `Delicious 51'. Seed of parents and reciprocal F1, F2, and BC families were incubated for 14 days on absorbent wadding in petri dishes at 15C. Days elapsed to radicle emergence among progeny from reciprocal crosses and segregating populations indicated the existence in the CG line of a cytoplasmic factor and recessive nuclear genes for cold germinability. Based on Fz and BC segregation, it appears that at least three or four recessive genes confer cold germinability. High levels of cold germinability in a seed population required the presence of both the cytoplasmic factor and nuclear genes for cold germinability.

Several leading Eastern muskmelon varieties were evaluated for their postharvest characteristics. The varieties evaluated were `All Star', `Athena', `Eclipse', `Legend', `Quasar', `Starship', and `Superstar'. The fruit were harvested in multiple harvests from 1 July through 10 Aug. 1996. Postharvest measurements taken included soluble solids (%), firmness, rind and flesh color, respiration, flavor quality, damage after drop tests, storage life, and shipping ability. The fruit of each cultivar were harvested at “half-slip” and “full-slip” and fully evaluated at each level of maturity. Most of the cultivars had similar postharvest characteristics, except `Superstar', which had the lowest overall ratings. Firmness ratings were highest for `All-Star', `Athena', and `Legend' and were lowest for `Superstar'. The flavor quality was similar for most cultivars and lowest for `Superstar' fruit. This trial will be repeated in 1996 and promising cultivars will be recommended for midwestern Unites States production.

`Gulfstream' and `Charentais' muskmelons (Cucumis melo. L.) plants were regenerated by in vitro culture to increase their genetic variability for resistance to root-knot nematodes (Meloidogyne spp.). While no genetic variability for root knot resistance was found, regenerated plants exhibited other traits that varied from the donor cotyledons. Chromosome counts confirmed that >75% of the somaclonal variants were tetraploid (2n = 24; 4n = 48). Tetraploids consistently exhibited micro- and macroscopic morphological changes that enabled distinction between tetraploids and diploids without chromosome counts; tetraploids contained enlarged stomates with more chloroplasts in the guard cells and pollen with a high percentage of square-appearing shapes. Tetraploids exhibited distinctive macroscopic morphological changes, including differences in leaf structure, fruit shape, blossom-end scar, number of vein tracts, and seed size.

A management expert system that enables producers to fully assess the integrated resource requirements, management risks, and profit potential for growing muskmelon was developed. The expert system environment Guru was used as the development software.
