inter-specific hybrids in beta genus using embryo rescue technique
interspecific or intergenus hybridization in sugarbeet (b. vulgaris l.) is usually failed due to non fertilization, embryo death or absence of connection between embryo and endosperm. consequently invitro embryo rescue technique is of value to save hybrid embryos before annihilation. sugar beet inter-specific crosses with wild species is impossible in classical breeding because of no chromosoma...
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 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 کاملInterspecific Hybrids
The regulation of gene expression is essential for organismal form, function, and fitness. Complex organismal development from zygote to adult requires finely tuned expression of genes in space, time, and abundance. Proper expression of genes is also required for most other aspects of physiology and function. Even minor changes in gene expression have the potential to significantly impact pheno...
متن کاملInterspecific hybridization in Brassica juncea and Brassica tournefortii through embryo rescue and their evaluation for biotic and abiotic stress tolerance.
Interspecific hybrids were obtained in an otherwise incompatible cross Brassica juncea x Brassica tournefortii through in vitro culture of hybrid embryos. The best response was observed from culture of embryos excised 20 days after pollination on MS medium supplemented with kinetin, alpha-naphthylacetic acid, gibberellic acid, glutamine and casein hydrolysate. One hybrid plant had many distinct...
