2 Conclusion
This study has revealed the existence of considerable genetic variation among the tested chili genotypes that
indicates the presence of excellent opportunity to bring about improvement. Rank distribution of genotypes within
cluster based on variance has indicated six promising parents from six clusters which can be used for 6X6 diallel
analysis. GT biplot has represented six potential parents from six different clusters with their suitable characters in
one frame which helps to select indirectly other appropriate traits and discard less important traits. Genotype 25
(Surjomukhi) is the superior genotype from cluster V and suitable for the improvement of characters yield/plant,
fruit weight and fruit length. As yield/plant is the most desirable trait for high yielding variety production,
therefore, genotype 25 (Surjomukhi) is by far the best parent for among the 30 genotypes for future hybridization
programme.
