population of mini-paprika cv. ‘Vine sweet-yellow’ and ‘Vine sweet-orange’. The direction and magnitude of association for
fruit characters showed less difference in two populations. Fruit yield had strong positive association with fruit number, fruit
weight and fruit length in both fruit forms of mini-paprika. Fruit width, fruit shape index, pericarp thickness and fruit
volume had significant positive correlation with fruit yield in both F2 populations. Path coefficient analysis showed that fruit
weight had highest direct effect (0.7400) in ‘Vine sweet-yellow’ and the highest direct effect (0.7390) in ‘Vine sweet-orange’
is due to fruit number. Fruit shape index showed the highest negative direct effect in both populations. Fruit length and fruit
volume expressed the highest indirect effect in ‘Vine sweet-yellow’ (0.5979) and ‘Vine sweet-orange’ (0.3761) via fruit
weight, respectively. Fruit weight in ‘Vine sweet-yellow’ and fruit number in ‘Vine sweet-orange’ are found to be most
important characters for improving the yield. A positive response to direct selection is possible for fruit number, fruit weight,
fruit length, and pericarp thickness in both F2 populations.
