Inheritance Studies of the Interspecific Cross of the Cucurbita Lundelliana Complex X Cucurbita Moschata
Two populations of Cucurbita were studied for the inheritance of corolla pigments. Flowers from them were collected--classified as orange, yellow, or cream--and analyzed for total carotenoid pigments. In most cases, chemical analysis for total pigments agreed with observed color designations. The ? 2 and backcross results fitted the expected 1:2:1 and 1:1 segregations, respectively, found in th...
متن کاملDevelopment 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 کاملRecombination in the genus Cucurbita.
ARIOUS structural and physiological barriers to recombination in species Vhyb rids often impose rigorous limitations upon the extent to which the characters of one species may be combined with those of another. Among such barriers structural and genic imbalance resulting in the differential elimination of gametes and zygotes of recombination types has often been mentioned (ANDERSON 1939; DEMPST...
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...
