Correlation and path analyses for oleoresin yield and yield components were conducted for C. annuum (CA 653, Arka Lohit, Ujwala and KTPL-19), C. chinense (CA 640 and CA 645), C. frutescens (CA 671 and CA 648) and C. baccatum (CA 670) cultivars grown in Kerala, India during the summer (January-March), rainy (May-July) and winter (September-November) seasons [year not given]. Genetic correlation analysis revealed that oleoresin yield was positively correlated with number of fruits per plant, and negatively associated with number of days to fruit set, flowering and harvesting. The number of days to flowering was positively associated with number of days to first fruit set and first harvest, and fruit yield per plant. The number of days to fruit set had a significant and positive association with number of days to first harvest and negative association with number of fruits per plant. The number of days to harvesting was negatively associated with number of fruits and fruit yield per plant. Path analysis indicated that the number of days to flowering had a positive direct effect on oleoresin yield. The number of days to harvesting and number of fruits per plant had negative direct effects on oleoresin yield.
