Acquisition, identification and analysis of an interspecific Capsicum hybrid (C. annuum × C. chinense)
SummaryUsing an embryo rescue technique, we obtained an F1 plantlet whose female parent was a purple chilli pepper (Capsicum annuum 7033) and whose male parent was a green chilli pepper (C. chinense 7020).We verified the origin of this interspecific hybrid using a peroxidase isozyme assay and random amplified polymorphic DNA (RAPD) markers. Most of the morphological features of the F1 plant, particularly the purple colour of its foliage, flowers and immature fruit, were intermediate between those of its parents. Cytological analysis indicated that the meiotic chromosomes of the pollen mother cells of the F1 plant exhibited abnormal behaviour, resulting in a marked reduction in the proportion of fertile pollen compared to both its parents. Sequence analysis of the internal transcribed spacer of nuclear ribosomal DNA demonstrated that, compared to the parental sequences, the F1 hybrid had 186 polymorphic sites, 139 of which (74.7%) were inherited from the male parent, and 23 (12.4%) were inherited from the ...
期刊介绍:
The Journal of Horticultural Science and Biotechnology is an international, peer-reviewed journal, which publishes original research contributions into the production, improvement and utilisation of horticultural crops. It aims to provide scientific knowledge of interest to those engaged in scientific research and the practice of horticulture. The scope of the journal includes studies on fruit and other perennial crops, vegetables and ornamentals grown in temperate or tropical regions and their use in commercial, amenity or urban horticulture. Papers, including reviews, that give new insights into plant and crop growth, yield, quality and response to the environment, are welcome, including those arising from technological innovation and developments in crop genome sequencing and other biotechnological advances.
