Description Seed size is an important trait in kabuli chickpea
(Cicer arietinum L.). The kabuli chickpeas with a
100-seed weight of >40 g garner higher market
price as they are preferred by consumers. The
objective of this study was to evaluate a sample
of chickpea landraces, breeding lines, and
cultivars for morphological traits and yield and
identify lines that are high yielding and exhibit
stable performance across environments. We
evaluated 65 large-seeded kabuli lines identifi
ed from the ICRISAT germplasm collection in
three sets, 18 trials, and 13 environments for 22
qualitative and quantitative traits. Several highly
signifi cant correlations were observed in all
three sets and a few large-seeded high-yielding
lines with stable yield were selected. Two extralarge-
seeded (100-seed weight > 50 g) lines ICC
17109 (Blanco Sinaloa 92), a breeding line, and
ICC 17452 (CuGa 288), a landrace, both originating
from Mexico showed high yield potential and
were moderately stable across environments.
The small-seeded control cultivars, though high
yielding, were highly unstable, performing better
only in favorable environments. The study
has also shown that some vegetative characteristics
were more sensitive to stress than yield
and yield components, hence selection in unfavorable
environments should be based on grain
yield and its components.
