Summary Significant heterosis for earliness and yield has been reported for cucurbits. Many cucurbit genes for disease resistance are dominant, and F1 hybrids with resistance to some diseases may be developed from crosses with only one resistant parent. Hybrid cultivars are very important for cucumber, squash, melon, and watermelon. Heterosis has also been reported for Benincasa, Lagenaria, Luffa, Momor-dica, and Trichosanthes. Inbred lines without serious depression of vigor have been… Expand
Development and evaluation of interspecific Cucurbita maxima x Cucurbita moschata hybrids for processing squash
TLDR
Interspecific hybrids derived from crosses of C. maxima x C. moschata F1 hybrids for use as processing squash exhibited prolific leaf canopy formation prior to fruit set and all interspecific hybrids observed were highly gynoecious. Expand
Performance of interspecific Cucurbita rootstocks compared to their parental lines
TLDR
The results suggest that the superiority of the hybrid over its parents and the benefit of the interspecific Cucurbita rootstock are not conclusive and varies among crosses and traits. Expand
Cucurbits as a model system for crop pollination management
TLDR
Synthesising studies on cucurbits’ requirement for pollination and how pollinators vary spatially and temporally in the landscape can extend beyond cucurbit systems to inform growers and pollination ecologists of other pollinator-dependent crop species wishing to maximise pollination services, species conservation; or both.

YIELD AND HETEROSIS IN CUCUMBER INBRED LINES CROSSES
YIELD AND HETEROSIS IN CUCUMBER INBRED LINES CROSSES The objective of this work was to evaluate yield of eight cucumber inbred lines and heterosis of hybrids from intercrosses parcial diallel (4 xExpand
Development of Advanced Interspecific-bridge Lines among Cucurbita pepo, C. maxima, and C. moschata
TLDR
The results demonstrate that a two-or three-species bridge line with crossing compatibility can be created by two- or three- species recombination and continuous selection and could provide a powerful platform for breeders to transfer favorable traits freely among the species and create more valuable and unique types or varieties through a conventional breeding process. Expand
Standard Heterosis in Cucurbita moschata and Cucurbita pepo Interspecific Hybrids
TLDR
Standard heterosis and broad sense heritability in vegetative, fruit yield, yield components, and qualitative characteristics in hybrids from fruit-type groups in C. pepo and C. moschata and some interspecific hybrids have superior yield and qualitative traits are examined. Expand
Engineering Non-transgenic Gynoecious Cucumber Using an Improved Transformation Protocol and Optimized CRISPR/Cas9 System.
TLDR
This study aimed to establish an improved transformation protocol for cucumber and to generate a gynoecious cucumber line through CRISPR/Cas9mediated mutagenesis of CsWIP1. Expand
Hybrid Cucumber
Summary Cucumber is a member of Cucurbitaceae comprising 90 genera and 750 species. It is consumed as salad or in pickled form. Cucumber is a low energy and high water content vegetable and is mainlyExpand
Note PERFORMANCE OF ADVANCED GENERATION FROM A HYBRID JAPANESE CUCUMBER Victoria
Inbreeding reduces the vigor in plants as a result of a decrease in the proportion of heterozygous loci. However, the influence of inbreeding is different among the species. The objective of thisExpand
Seed Production and Germinability of Cucurbit Crops
Cucurbit crops are mostly produced for their immature or mature fruits. However, a relatively high proportion of cucurbit fields are destined for seed production, either for seed consumption or forExpand

Heterosis in Vegetable Crops
TLDR
Programs to exploit the sex systems to produce hybrids were developed in spinach (monoecious forms), cucumber (genetic controlled), squash (response to chemical), and carrot (cytoplasmic male sterility). Expand
Evaluation of combining ability, heterosis and genetic variance for plant growth and fruit quality characteristics in Thai-melon (Cucumis melo L., var. acidulus Naud.)
TLDR
Correlations between the performance of parents and the average of their hybrids were positive in almost all cases except vine length, and only the correlations on number of fruits per plant and shape index were significant. Expand
Development of Genic Male-sterile Watermelon Lines with Delayed-green Seedling Marker
TLDR
The segregation ratios obtained from F2 and BC1F2 populations suggest that the male-sterile and delayed-green traits are inherited independently and that delayed green is inherited as a single recessive nuclear gene. Expand
Assessment of combining ability, heterosis and genetic variance for fruit quality characters in muskmelon (Cucumis melo L.).
TLDR
Favourable heterosis over midparent was observed for fruit yield, fruit number, fruit weight, fruit bearing branches, node of first female flower, days to harvest, and vine length. Expand
Cucumber (Cucumis sativus L.).
TLDR
Two novel Agrobacterium tumefaciens-based methods of cucumber transformation are described, including direct regeneration from leaf microexplants selected on kanamycin-containing medium and regeneration from a long-term established embryogenic suspension culture emitting green autofluorescence (GAF) and selection on medium containing hygromycin.

Femaleness in breeding glasshouse cucumbers
TLDR
To prevent the formation of bullnecks due to pollination by bees the possibilities of breeding female-flowered varieties were explored, and a rather pronounced female character was desirable. Expand
Earliness in F1 hybrid muskmelons and their parent varieties
TLDR
Partitioning the total growth period demonstrated that a hybrid could exhibit apparent heterosis for early maturity without exhibiting heterosisFor either early flowering or early ripening, as measured by the time from planting to first pistillate flower and to first ripe fruit. Expand
Pollination Requirements for Watermelon Seed Production
TLDR
Watermelon pollination studies in southern Colorado, USA, indicated that insect pollinators were necessary for commercial seed production, and that honeybees were adequate pollinators, and six species of native bees seemed to be active pollinators. Expand
Melon: Cucumis melo L.
TLDR
This chapter discusses the germplasm resources and reproductive biology of melon, and further reviews the selection of breeding methods for melon and the breeding methods and strategies used formelon. Expand
Reduction of the cost involved in hybrid seed production of pumpkins (Cucurbita maxima Duchesne)
TLDR
Treatment of the female parental line at the two and four true leaf stage with Ethrel 48, together with natural pollination by bees, reduced the labour input by 90% and resulted in the production of high quality hybrid seed. Expand
