Green fruits were harvested for analysis of ascorbic
acid content.
The data was subjected to analysis for general and
specific combining ability as method given by
Griffing (1956). The graphic analysis for combining
ability was based on the variance-covariance analysis
following the methodology given by Hayman (1954).
The heterosis was estimated as per cent deviation of
F

hybrid performance from the better parent as well
as over standard check.
3 Conclusion
From the above results, the promising crosses based
on combining ability and heterosis for different
quality traits were MS 341 x PP 403 for dry matter
content, SL 461 x DL 161 for ascorbic acid in green
fruits, SL 462 x VR 521 for ascorbic acid in red fruits,
DL 161x PP 402 for Capsaicin in powder, SL 461 x PP
403 for oleoresin content, DL 161 x PP 402 for
capsaicin in oleoresin, SL 462 x VR 521 for colouring
matter in powder and DL 161 x SL 462 for colouring
matter in oleoresin. Thus, these best performing
crosses have the potential of beingcommercially
exploited at the farmers’ field. Also, the present study
hadstressed preponderance of non-additive gene
action registering over-dominance coupled with
undesirable linkages. Heterosis breeding could be
more useful to circumvent quality traits by developing
hybrids. However, breeding procedures such as triple
test cross, reciprocal recurrent selection, bi-parental
mating and/or diallel selective mating which provide
better opportunities for selections, recombination,
dislocation of unworthy linkages and accumulation of
favourable genes are proposed for amelioration in
quality traits in chilli.
