The influence of gamma ray doses (25, 50, 75, 100, 200, 300 and 400 Gy) and genotypes (Eskenderany F1, Acceste F1, Sakiz, Urfa Yerli) on the induction of haploid embryos obtained by irradiated pollen technique was studied in squash (Cucurbita pepo L.). Different shapes and stages of embryos were derived from seeds extracted from fruits harvested 4–5 weeks(More)
The influence of pollen irradiation on the production of in vitro haploid plants from in situ induced haploid embryos was investigated in winter squash (Cucurbita maxima Duchesne ex Lam.). Pollen were irradiated at different gamma-ray doses (50, 100, 200 and 300 Gray) and durations (9, 11, 15, 21, and 28 July). Production of in vitro haploid plantlets was(More)
The production of large numbers of haploids is the crucial point of the dihaploidisation process. Although in vitro haploid plants were successfully produced by irradiated pollen technique in winter squash (Cucurbita maxima Duch.) and pumpkin (Cucurbita moschata Duch.), the frequency is still insufficient for using in a large-scale breeding programme. Thus,(More)
