Abstract
"Investigations were carried out to know the nature and magnitude
of gene effects for VN2 X Jwala, VN2 X Arkaloh t, Hissar Shakti X
PMR21, Byadagi Kaddi X Arkalohit and Byadagi Dabbi X LCA312
crosses for qualitative and quantitative characters and selection of
superior segregants in F3 of five crosses in chilli during kharif 2000-
2001. The study also involves identification of promising recombinants
from F3 populations in five crosses.
To understand the nature and magnitude of gene effects five
crosses were analysed through generation meaa analysis for 13
characters. The study indicated that the growth related traits were found
to be under the control of dominance and additive x additive type of gene
interaction.
Fruit related traits were under the control of additive, additive x
additive type of gene interaction. Resistance to th'ips and mites was
under the control of additive gene and additive x additive effects i.e., it
suggest that inclusion of parents having high level of resistance for the
development pure lines. Dry fruit yield was under the control of
dominant and additive type of gene action.
In order to exploit non-additive gene action development of hybrid
is suggested. For the development of variety recurrent pedigree selection
programme is suggested involving the parents having high level of
resistance with high fruit quality traits.
Among the superior segregants identified in five segregation
population, more number of superior segregants recovered from the VN2
X Jwala -cross followed by the VN2 X Arkalohit cross. In VN2 X Jwala
cross, 9632-8 and 9632-56 are found to be dry chilli purpose. 9608-7,
9632-67, 9646-18 and 9646-47 appear to be promising for deriving leaf
curl complex resistant genotypes recovered from the five crosses studied
with high yielding ability."
