Abstract

The experiment was conducted in humid agro ecological zone of Calabar, Nigeria, to evaluate the yield performance and the association between yield and yield related components of some capsicum genotypes which include; Bird pepper(Capsicum annuumvar. aviculare), Habanero pepper(Capsicum chinense), Thai pepper(Capsicum annuum var.glabriusculum),Tabasco pepper(Capsicum frutescens) and Bell pepper(Capsicum annuum. Var.accuminatum). Randomized complete block design was used for the experiment, planted in all three replications. The result showed that all the genotypes of pepper used were significantly different (P = O.O 5) in plant height, number of branches, fruit length, fruit breadth, number of fruit per plant and total fruit yield but no significant differences was observed in days to 50% flowering and leaf area. The cultivar Tabasco pepper gave the highest yield of 2426.66 kg/ha followed by bird pepper with a total yield of 2239.99 kg/ha while the cultivar Hebanero pepper gave yield of 1907 kg/ha. The least yield was recorded on Thai pepper with 1520Kg/ha and bell pepper gave 1680 kg/ha. The linear correlation analysis of the yield and yield related component revealed that days to 50% flowering (r = 0.613), fruit length (r =0.392), number of branches (r = 0.913), number of fruits per plant (r = 0.422) and plant height (r = 0.424) showed positive relationship with fruit yield. The yield component with positive and significant correlation can be used as selection indices for the improvement of capsicum speciesKEYWORDS: Components, Correlation, Genotypes, Pepper, Yield.

Highlights

The genus Capsicum known as pepper is an annual shrub with many branches belonging to the family Solanaceae
The results of the field evaluation of five capsicum genotypes for yield performance and association with yield related components are presented in table 1
The mean performances of the genotypes shows a clear indication of agronomic superiority of genotypes over others such as Tabasco pepper(Capsicum frutescens) with fruit yield of 2,426.6kg/ha and Bird pepper(Capsicum annuum) with yield of 2,239.9 kg/ha

Summary

Introduction

The genus Capsicum known as pepper is an annual shrub with many branches belonging to the family Solanaceae. It is one of the most important vegetables grown in Nigeria and other parts of humid and semi-arid tropics (Aliyu 2000). Pepper is used in all kinds of cookery as pungent species. It is used in seasoning sauces, soup and other dishes. Pepper like other vegetable crops contributes nutritiously in nutrients that may be lacking in other food materials (Grubben 1997). The fruit can be dried, ground to powder and use as ingredient in curry powder (Dewitt and Bosland 2009)
