Abstract

An Oriental pickling melon (Cucumis melo var. conomon) was crossed with a hermaphroditic melon, and the hermaphroditic form also was crossed with a birds-nest-type melon, with the goal of producing pickling melon breeding lines possessing a concentrated yield. Hermaphroditic and birdsnest breeding lines derived from these crosses produced markedly more fruits per plant and per unit area in a once-over harvest than did the pickling cucumber cultivars tested.

Abstract

Eight accessions of muskmelon (Cucumis melo L.) possessing one of 3 growth habits, vine, short-internode, and birdsnest, were germinated at 15°C. All 3 birdsnest lines had at least 85% germination after 12 days incubation, whereas all vine and short-internode lines tested had 0% germination. Various seed pretreatments, including presoaking in aerated water for 24 hours, had beneficial effects on germination of birdsnest types at this temperature.

Abstract

Two precocious yellow-fruited zucchinis (Cucurbita pepo L. cvs. Goldy and Gold Rush) and a green-fruited control, ‘Burpee Hybrid Zucchini9, were compared for yield and yield quality in a series of 6 trials conducted in Israel. Overall, ‘Goldy’ and ‘Burpee Hybrid Zucchini’ produced a similar number of fruits and yield of “Grade A’’ fruits, but ‘Gold Rush’ produced significantly less. Yield quality, expressed as the percentage of “Grade A” fruits, was higher in ‘Goldy’ and ‘Burpee Hybrid Zucchini’ than in ‘Gold Rush’. Off-color fruit production was the most important parameter which reduced yield quality in ‘Gold Rush’.
