Field experiments were conducted during 2008, rainy and dry seasons at National Horticultural Research Institute, (NIHORT) Ibadan to investigate qualitative traits, of 31 accession of long cayenne pepper. The experiment was laid out in a randomized complete block design with three replicates. Seedling were raised in the screen house for six weeks before transplanting into field at 60cm x 60cm, on the bed measuring 3.6m x 2.4m. result showed that in the two seasons plant growth habit for first season had 96.8% intermediate, 3.2% erect whereas the second season had 100% intermediate, leaf shape in both season displayed variation with first season 91.4% deltoid shaped with 8.6% ovate shaped while the second displaying 96.8% deltoid and 3.2% ovate .other accession displayed uniform expression across the season at anthesis. The mean performance of 31 accessions for 17qualitative agronomic characters at harvest had 7 traits with high variation among accessions and 10 traits displaying similar traits among accessions and across the season which suggested that there is much variability existing in the population respectively. It was however, concluded that yield requires knowledge of the magnitude of variation in the available germplasm, interdependence of the quantitative and qualitative characters with yield, extent of environment influence on these factors, heritability and genetic gain of genotypic materials.
