Abstract
Field and laboratory experiments were conducted at the Main Agricultural Research Station,
Dharwad and in the laboratory of Department of Seed Science and Technology, University of
Agricultural Sciences, Dharwad during rabi 2007-08 and 2008-09.
Nipping at 30 DAS and growth regulator foliar spray in A-1 and ICCV-2 chickpea varieties
revealed that over of nipping and growth regulators, A-1 recorded more number of branches and
pods per plant with higher seed yield and better seed quality parameters compared to ICCV-2.
Nipping showed beneficial influence on number of branches and pods per plant with higher seed yield
(28.50 q/ha) and better seed quality. Among growth regulators, NAA (50 ppm) followed by Tricontanol
(0.1%) resulted in more number of branches and pods per plant with higher seed yield (29.91 and
27.80, respectively) with better seed quality parameters. The interaction effect of varieties, nipping
and growth regulators also showed similar beneficial influence on seed yield and quality.
The field study on seed size grades on seed yield and quality in five chickpea varieties
revealed that big and medium seeds produced more seed yield (33.11 and 32.05 kg/ha, respectively)
with better seed quality parameters compared to small seeds. Seed yield and quality were more in
Desi over Kabuli chickpea varieties. The interaction effect showed that big seeds of Desi and Kabuli
types were better in seed yield and quality compared to small seeds.
The storage study indicated that Desi varieties maintained satisfactory germination upto 8-9
months while Kabuli types upto 7-8 months. Among seed size, small and medium seeds were
relatively more in storage potential that other seed grades.
In all the chickpea varieties, 100 seed weight and moisture content decreased significantly
with advance in maturity, while, germination and vigour index increased. Seeds harvested at full
yellow pod colour stage (H3) recorded higher germination (96.40%) and seed vigour.
The morphological characters viz., stem colour, pigmentation, foliage colour, pod colour, seed
coat colour, test weight etc. were found more reliable parameters for varietal characterization in
chickpea varieties.
