Influence of gamete selection for wilt resistance in the F1 generation on the variability of non-target quantitative traits in F2 generation of chickpea

Published on

Chickpea (Cicer arietinum L.) despite its broad
adaptation, production is restricted by several biotic and
abiotic stresses. Among biotic stresses, Fusarium wilt
caused by Fusarium oxysporum f.sp. ciceris is the major
limiting factor for chickpea productivity. The best strategy
to manage this disease is through use of resistant
cultivars. Gamete selection is effective technique, which
can be easily combined with conventional methods to
develop resistant varieties in short time [1-3]. By
artificially imposing various selective pressures during
the process of gamete formation and fertilization in the
F1 generation, one can increase the frequency of plants
with the targeted trait. The application of gamete
selection for wilt resistance has increased the frequency
of resistant plants in segregating population [1]. Gamete
selection may produce resistant plants but there are
chances that it may result in low productivity due to
linkage drag. The present study was undertaken to
analyze effect of gamete selection for wilt resistance
on segregation and variability of non-targeted
quantitative traits in the F2 generation.
