Evaluation and taxonomy of agronomically important Striga species
(1996)Taxonomic studies of the taxa clustered about Striga asiatica, S. hermonthica, and S. gesnerioides are presented based on a cladistic study of African plants. The S. asiatica cluster includes S. elegans, S. hirsuta, and S. lutea. Striga asiatica is considered to be derived from a native species near S. elegans. Artificial hybridization indicates a close relationship between S. hermonthica and S. aspera. Several host morphotypes of S. gesnerioides were examined. While each morphotype exhibits ... -
Advanced Musa yield trial at the University of Ghana Agricultural Research Station, Kade; 2: banana weevil and nematode resistance
(1996)The Plantain and Banana Improvement Program (PBIP) of IITA has developed black Sigatoka resistant tetraploid hybrids of plantains (PITA) and cooking banana (BITA). The main selection criteria were black Sigatoka resistance, yield, and fruit quality. However, it was felt necessary to also determine the resistance of these accessions to natural infestation by banana weevil and nematodes which are the most important pests of plantains. This report concerns weevil and nematode damage during the first ...
