Description The present investigation on “Heterosis and
combining ability studies in chickpea (Cicer arietinum L.) was
carried out at the Pulses Improvement Project, Mahatma Phule
Krishi Vidyapeeth, Rahuri during Rabi 2011-12 with the
objectives to study the general and specific combining abilities,
extent of relative heterosis and heterobeltiosis. Seven parental
diallel (without reciprocal) was effected. Parents and their 21
F1’s were studied for heterosis and combining ability. The data
were analysed statistically as per Model-I and Method-II of
Griffing (1956). Observations were recorded for days to 50 per cent
flowering, days to maturity, plant height, plant spread, number
of primary branches per plant, number of secondary branches
per plant, number of pods per plant, number of seeds per pod,
100 seed weight and seed yield per plant.
Parents and hybrids were highly significant for
studied eight characters which revealed amount of variability
was present in experimental material.
The parents ICCV-42 (43.5 days) and Phule G-00108
and ICCV-09112 (107.5 days) were the earliest with respect to
days to 50% flowering and maturity respectively.
Among the crosses, Phule G-00108 x ICCV-42 (43.5
days) and AKG-72 x Phule G-96006 and Phule G-00108 x ICCV
42 (105.5 days) were earliest with respect to days to 50%
flowering and maturity, respectively.
Highest number of pods per plant were observed in
the parent AKG-72 (124.15) and in cross Phule G-00108 x ICCV
09112 (168.3). The highest seed yield per plant (26.65g) was
observed in the parent AKG-72. Among the crosses, AKG-72 x
ICCV-09112 recorded highest seed yield (42.28g) per plant.
The parent ICCV-09112 recorded maximum 100 seed
weight (24.55 g). The cross Phule G-00108 x ICCV-42 (33.10g)
recorded highest 100 seed weight.
