Pyramiding of drought avoidance/tolerance mechanisms - earliness, root weight and root length through multiple introgression in chickpea (Cicer arietinum L.)

Published on

In chickpea (Cicer orietinum) the terminal drought is a
major constraint that limits the productivity. Efforts to
breed drought tolerant varieties in the past have not
been rewarding because of imperfect understanding of
drought manifestation using yield as an empirical
selection criterion [1]. Plant breeders have categorized
this drought tolerance mechanism in three categories
viz. drought escape (early phonology of ICCV-2),
drought avoidance by reduced leaf area and narrow
leaflets (ICCV-10448) and drought tolerance through
large root mass (ICCV-4958) [2]. Present investigation
was therefore planned to introgress these different
mechanism using three breeding lines (ICCV-2, ICCV-
4958 and ICCV-10448) as a source for one or the other
mechanism of drought tolerance in to agronomically
preferred variety Annigiri (A-1). Evaluation of breeding
population was done during rabi season of 2004. There
was typical drought situation during that year as there
were no rainfall during croping period of chickpea.
