Genetic analysis of pod borer (Helicoverpa armigera) resistance and grain yield in desi and kabuli chickpeas (Cicer arietinum) under unprotected conditions

Published on

Half-diallel cross progenies of desi (45F1s and 45F2s) and
kabuli (28F1s and 28F2s) chickpeas (Cicer arietinum) along
with their parents (10 desi and 8 kabuli) with varying levels
of pod borer resistance (PBR) were evaluated in replicated
field trials under unprotected conditions during 2001-2002
post-rainy season at International Crops Research Institute
for the Semi-Arid Tropics (ICRISAT), Patancheru, India to
study the inheritance of pod borer, Helicoverpa armigera
(Hub.), and grain yield. Additive genetic variation was
important for the inheritance of PBR in desi chickpea.
However, both additive and dominance genetic variations
were important in the inheritance of PBR in kabuli
chickpea. However, dominance genetic variation was
predominant in the inheritance of grain yield in both desi
and kabuli chickpeas. The correlation coefficient between
general combining ability (gca) effects estimated based
on data of F
1 and F2 generations was fairly higher, while it
was lower for specific combining ability (sca) effects in
desi chickpea for PBR. The correlation coefficient between
gca effects and between sca effects estimated based on
F
1 and F2 generations’ data for PBR in kabuli chickpea and
for grain yield in desi and kabuli chickpeas were very low.
Chickpea lines with significant gca effects for PBR and
grain yield in desi and kabuli chickpeas were identified.
The implications of study results are discussed in relation
to strategies to enhance PBR and grain yield levels.
