Barriers to interspecific gene exchange in Capsicum


, : Barriers to interspecific gene exchange in Capsicum. Capsicum Newsletter (Special issue): 57-60

The principal problems involved are discussed under the following headings: stylar inhibition of pollen tubes; post-fertilization abortion of hybrid seeds; and hybrid sterility and chromosomal rearrangements.

Observations of chromosome pairing in the interspecific hybrid indicated that the white-flowered C. baccatum accession SA219 differed from the purple-flowered C. cardenasii accessio...

Since anthracnose resistance was only identified in Capsicum baccatum germplasm, interspecific hybridization had to be conducted to transfer the resistance gene(s) from C. baccatum into C. annuum. Fruit set and seed formation after pollination and...

Some cultivars of Capsicuum annuum show dwarfness in their interspecific hybrids with C. chinense 'No. 3341'. The dwarfness is represented by the termination of leaf differentiation after development of several leaves in both main and la...

To define the cytogenetical relationship between Capsicum annuum and C. baccatum, the patten of chromosome pairing at meiotic metaphase in the F1 hybrid was analysed. The average frequency was 0.02 for univalents, 8.93 for bivalents, 0.08 for triv...

For the crosses with accession BGH1757, seed germination was 22.4-77.4% and plant survival was >70.8%. The hybrid BGH1757 X BGH16...
