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. |
