Asymmetric somatic hybrids between Lycopersicon esculentum and irradiated Lycopersicon peruvianum
Theoretical and Applied Genetics, 1990Asymmetric somatic hybrids of Lycopersicon esculentum and Lycopersicon peruvianum were obtained by fusion of leaf protoplasts from both species after irradiation of protoplasts or leaf tissue of L. peruvianum with 50, 300, or 1,000 Gy of gamma-rays. These radiation doses were sufficient to abolish the growth of the L. peruvianum protoplasts.

The chromosomes of tomato are clearly distinguishable at pachytene stage of meiosis, thus the differentiated structure of all the chromosomes was demonstrated to be adequately useful for various types of studies. Tomato chromosomes have been the subject of intensive study of polyploids, especially of aneuploids which facilitated the assigning of genes ...

Somatic hybrids of the cultivated tomato, Lycopersicon esculentum, and a wild species, L. peruvianum, were obtained by fusion of leaf protoplasts from both species in the presence of poly-ethylene-glycol (PEG) or in an electric field. The somatic hybrids were selected on the basis of kanamycin resistance of L.

Tomato is the major fruit and vegetable crop produced worldwide. India is the second-largest producer of tomato after China. According to FAOSTAT 2018, India produced18.74 million tons with productivity rate 21.24 ton/Ha. Consumption of tomato fruits is considered as healthy diets that have potential to reduce the risk of cancer, osteoporosis and ...

Electrophoretic technique combined with enzyme-specific stains has provided the most precise way of estimating genetic variability in many plant taxa. Within the genus Lycopersicon this method has been successfully applied by Rick and his colleagues for measuring the extent of variation both in cultivated forms and wild species (Rick 1976a, 1983 ...

Aims. Capability for rooting of the peruvian and cultivated parental forms of the tomatoes (Lycopersicon peruvianum var. dentatum Dun. and Lycopersicon esculentum Mill.) and their cybrids with reciprocal plastom-genome organization as well as with back transferred chloroplasts was investigated. Methods.

Somatic hybrids were obtained after protoplast fusion of sexually incompatible species of L. esculentum and L. peruvianum v. dentatum. Genetic novelty of the hybrids in question was shown by study of the chromosome number, isozymes (esterase, peroxidase), a small subunit of RuBPCase and chloroplast DNAs.
