Development of Advanced Interspecific-bridge Lines among Cucurbita pepo, C. maxima, and C. moschata
Interspecific hybridization among the three most economically important cultivated species of Cucurbita spp., Cucurbita pepo, C. moschata, and C. maxima can be made but not readily. By means of various pollination measures, different mating systems, and varying selection methods, nine advanced interspecific-bridge lines were developed, in which the crossing barrier among the species and the mal...
متن کاملProduction of Cucurbita Interspecific Hybrids Through Cross Pollination and Embryo Rescue Technique
Interspecific hybridization is an important method to widen variations and to develop novel cultivars. Interspecific cross-pollination was carried out among three species of Cucurbita (C. moschata, C. ficifolia and C. martinezii) as male parents with ten cultivars of C. pepo as female parents. Only four cultivars of C. pepo (Eskandarani cv., Queen F , Jedida F and MHTC77 F ) were successful in ...
متن کاملthe possibility of interspecific hybridization between summer squash (cucurbita pepo) and pumpkin (c. moschata)
interspecific hybridization occurs among cucurbia species it is commonly used for grafting, yield increasing and production of pest resistant rootstocks. in the present research probability of interspecies hybrid generation among seven lines of cucurbita pepo (p1, p4, p5, p6, p10, p22, p25) and six lines of cucurbita moschata (mo3, mo5, mo6, mo9, mo11, mo12) were investigated. after crossing of...
متن کاملUV-C irradiation reduces microbial populations and deterioration in Cucurbita pepo fruit tissue.
Tissue slices of zucchini squash (Cucurbita pepo L., cv. Tigress) fruit were exposed to ultraviolet-C (UV-C) radiation from germicidal lamps for 1, 10 or 20 min; however, only 10 and 20 min UV-C exposure significantly reduced microbial activity and deterioration during subsequent storage at 5 or 10 degrees C. UV-C treated slices had higher respiration rates than controls; however, the ethylene ...
متن کاملDistribution of a - Galactosidase in Cucurbita pepo
The distribution of a-galactosidase (a-D-galactoside galactohydrolase IEC 3.2.1.221) in Cucurbita pepo has been determined in an attempt to assess its involvement in hydrolysis of transport sugars of the raffinose oligosaccharide series (la-1-6-galactopyranosyllj sucrose). Extracts prepared from leaves and petioles at different stages of development, roots, flowers, dry and germinating seeds, a...
