Meiosis in sesquidiploid hybrids of Lycopersicon esculentum and Solanum lycopersicoides.
We have synthesized diploid hybrids between Lycopersicon esculentum and Solanum lycopersicoides and have converted them to allotetraploids. Two sesquidiploids, having two complements of the former parent and one of the latter, have been obtained by backcrossing the former parent with the alloploid. In meiosis of the sesquidiploid the L. esculentum chromosomes exhibit strong preferential pairing...
متن کاملIn situ embryo rescue for generation of wide intra‐ and interspecific hybrids of Panicum virgatum L.
Wide crosses have been used for decades as a method for transferring novel genetic material and traits in plant breeding. Historically, many products of wide crosses require tedious and inefficient surgical embryo rescue prior to embryo abortion to recover single plantlets. We have utilized transgenic switchgrass (Panicum virgatum L. cv Alamo) as a pollen donor in conjunction with antibiotic or...
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 کاملChromosome number variation in somatic hybrids between transgenic tomato (Lycopersicon esculentum) and Solanum lycopersicoides.
Leaf mesophyll protoplasts of Lycopersicon esculentum were fused with suspension-culture-derived protoplasts of Solanum lycopersicoides by a PEG treatment. Both species have the same chromosome number (2n = 2x = 24). The hybrid calli were selected using the full selection method - kanamycin resistance and culture conditions critical for L. esculentum protoplast divisions. The genomic in situ hy...
متن کاملThe Inheritance of Self-Incompatibility in Hybrids of Lycopersicon Esculentum Mill. x L. Chilense Dun.
OTH self-fertile and self-incompatible species are found in the genus BLycopersicon (LAMM 1950). The self-incompatibility in L. peruuianum was shown to be of the Nicotiana or multiple-allelic gametophytic type by MCGUIRE and RICK (1954). Less extensive evidence suggested similar genetic control in L. hirsutum, L. glandulosum, and L. chilense (L. peruvianum f . dentatum) . I n addition, the inhe...
