). Tolerance to root rot has been identified in cultivars of summer ( Cucurbitapepo ) and winter squash ( Cucurbita moschata ) and cucumber ( Cucumis sativus ) ( Hausbeck and Lamour, 2004 ; Meyer and Hausbeck, 2012 ; Ppoyil, 2011 ). Raised bed culture with
squash used for pies, jack-o'lanterns, or stock feed” ( Robinson and Decker-Walters, 1997 ). Pumpkin encompasses various Cucurbita L. species such as Cucurbitapepo L., C. maxima Duchesne, C. moschata Duchesne, and C. argyrosperma C. Huber
and Lamour, 2004 ; Sanogo and Ji, 2012 ). Cucurbita moschata Duchesne, Cucurbita maxima Duchesne, and Cucurbitapepo L. are the three main squash species cultivated in the United States, with the latter being the most economically important
species of Cucurbita genus, C. pepo L. is the most popular and consists of four subspecies: texana (Scheele) Filov (also called ovifera (L.) Decker); pepo ; fraterna (L. H. Bailey) Lira, Andres, and Nee; and gumala Teppner ( Gong et al., 2012
; Tian and Babadoost, 2004 ; Waldenmaier, 2004 ).
Cucurbitapepo L. (pumpkin, squash, gourd) is an economically important group of the Cucurbitaceae ( Paris et al., 2003 ). Eight cultivar groups of edible-fruited domesticates of C. pepo have been
Cucurbitapepo , C. moschata , and C. maxima are the most economically important three (out of five) cultivated species within the Cucurbita genus that include squashes, pumpkins, and gourds, which represent several species in the same crop
with black plastic BDM and PE mulch ( Cowan et al., 2014 ). Ghimire et al. (2018) found that yield of pumpkin ( Cucurbitapepo ) grown with brown paper mulch was lower than PE mulch and several black plastic BDMs, but similar to one black plastic BDM
The author of the article “A Gynoecious Line of B+B+Genotype in Cucurbita pepo” (HortScience 21:319, Apr. 1986), Oved Shifriss, wishes it noted that: “The genetic synthesis of gynoecism in Cucurbita is a subject of a pending application for a U.S. patent.”
The inheritance of fruit flesh color in Cucurbita pepo L. (squash, pumpkin) was studied in filial and backcross generation progenies of the cross between ‘Vegetable Spaghetti’, which has pale flesh, and ‘Precocious Fordhook Zucchini’, which has orange flesh. Orange flesh was found to be conditioned by two complementary dominant genes, B and L-2.
In a bush or dwarf breeding line of Cucurbita pepo var. ovifera a plant of extreme dwarf habit with a diameter of only 3.8 dm was found. The mutant proved to be true breeding and F1, F2 and F3 segregations from crosses to normal dwarf and both backcrosses indicated a Single gene difference between normal dwarf and extreme dwarf.
