Intraspecific reproductive variabilities in <i>Capsicum frutescens</i> (L.) in Nigeria
Abstract
Natural intraspecific and interspecific crosses among Capsicum species are very high, resulting in intermediary forms which are complex to categorize. It is likely that through these crosses, new species or varieties may have arisen. The present study evaluated intraspecific reproductive variablities among eight accessions of C. fructesens. Each accession was planted in 10-litre plastic buckets arranged in single lines of inter- and intra-row (70 cm x 50 cm) and filled with loamy soil in five replicates at the Department of Pure and Applied Botany Screen House, Federal University of Agriculture, Abeokuta (Latitude 7°9'N, longitude 30°21'E), Nigeria. Quantitative and qualitative reproductive characters were evaluated through measurements and visual observation, respectively. Means were separated using the Duncan's Multiple Range Test at p ˂ 0.05 (Statistical Analysis Systems version 9.2). The wide variation in the flower position, corolla colour, corolla spot colour, anthocyanin spots, fruit colour at intermediate and maturity, fruit set, days to flowering and fruiting, number of seeds per fruit and locules between AS002 and other accessions revealed that AS002 was significantly different. The study, therefore, suggests AS002 to be a new species in Nigeria, suspected to be C. baccatum, and also the best among the accessions for breeding purposes.
