Description |
The crosses between Arachis cardenasii accession ICG 11558 and cultivated groundnut produced an average of 29% pods and 47% of the pods had small seeds, which were physiologically immature. These pods did not germinated in vivo but when the embryos were dissected and culture, they germinated in vitro. A total of 18 hybrids were obtained. Pollen fertility in the F1 hybrids ranged from 4 to 8%. Backcross between the hybrids and cultivated groundnut produced pegs in large numbers (68%) and 8% of the pegs formed pods. In the pegs formed on the hybrid, growth of the embryo continued irrespective of peg growth. Interspecific derivatived in general and those between A. hypogaea and A. cardenasii in particular take a minimum of 60 days for seed maturation and another 6 months for vegetative growth before the initiation of flowers.
