The world’s food and agricultural programs have gradually declined into an unsustainable situation due to challenges such as increase in world population, varied agro-climatic regions, increase temperature, extreme sole-culture growing techniques, and water shortage. A considerable emphasis has been put on few staple food crops coupled with repeated dieting, food scarcity, and essential mineral deficits, frequently inducing dietary disorders. Because relying on staple crops may lead to serious food shortages in the future, we must adjust our dietary habits to include a diverse range of non-staple foods and maximize their use in order to achieve food security and reduce the nutritional gap. To assure healthy meals around the world, an authentic and reasonable strategy is presented to draw additional awareness towards variations in agricultural production techniques and dietary preferences. The EAT-Lancet declaration highlighted the importance of increasing agri-based foods to achieve sustainable health. Expanding overlooked crops with abundant genetic stocks and possibly beneficial characteristics is an approach that might meet food and nutritional security challenges. Although undervalued, pumpkin is a valuable vegetable herbaceous plant that contributes to global food and nutritional security. This crop has already been identified as a revolutionary age crop, balanced food, and more adapted to low soil and atmospheric circumstances than other major crops. This review paper focuses on the potential uses of pumpkin as an underutilized crop; diversification and development of hybrids, particularly hybridization breeding through diallel mating design; and how implementation of this “modern” technology would contribute to the breeding of the neglected pumpkin vegetable and stimulate productivity and nourish the world’s largest malnourished, deprived, and starved populations.

“…Commercial deployment of summer squash hybrids is increasing due to the obtained heterosis for yield and other traits (Marie et al, 2012;César et al, 2013;Abd El-Hadi et al, 2014;Hussien, 2015;Tamilselvi et al, 2015;Othman, 2016;Chaudhari et al, 2017 andKaripçin andİnal, 2017). Hybrids also have the possibility of combining parental resistance to various pathogens.…”

Ten parental lines were crossed in a line x tester (7L x 3T) mating design in the summer season of 2016 to obtain 21 F1 hybrids to study the genetic behavior of some economic traits for cultivars of summer squash crop suitable for Egyptian cultivation. In 2017 summer season, the ten parents and their 21 F1 hybrids were evaluated with four commercial checks "Aziad, Adronto, Marselia and Tabark" in the experimental design which was a randomized complete blocks with three replications at Kaha Research Farm of Vegetables Breeding Department, Horticultural Research Institute, (HRI), Agric. Res. Center (ARC) in the Kalyobiya Governorate. Data indicated that fifteen and ten crosses had highly significant values of heterosis over the midparents and the better parents, respectively for number of fruits/plant trrait. Concerning heterosis over the checks hybrids, four and two crosses showed significant and highly significant values of heterosis over hybrid Aziad and Tabark, respectively but only one crosses (P7xP10) showed highly significant positive values over the checks cultivars Adronto and Marselia. Meanwhile, all crosses showed insignificant values of heterosis over the midparents and the better parent concerning yield /plant trait. Heterosis over the checks hybrids, three, zero, once and once crosses gave significant or highly significant positive values of heterosis over Aziad, Adronto, Marselia and Tabark, respectively. Two lines and two testers gave significant or highly significant positive values of gca effects on number of fruits/plant trait. Also, three lines showed significant or highly significant positive values of gca effects on yield /plant trait. Therefore, these lines considered good combiners for yield traits. In concern of sca effects, three crosses out of twenty ones gave significant or highly significant positive values for total yield plant trait.
