Among cool season pulses, chickpea and lentil account for over 74% and 79%, respectively
of the total area and production under Rabi pulses in India. The climate change has resulted
in contraction of cool season duration, and as a result, terminal heat stress and root
diseases complex are constraining the productivity of both chickpea and lentil. This has
necessitated breeding novel genotypes with unique adaptive features to combat the adverse
impacts of climate change. Two crosses (BGD 9971 × IPCK 2002-29 and BGD 9971 × JG
16) of chickpea were advanced to succeeding generations commencing from 2014-15. In F 1
generation, one F 1 (BGD 9971 × IPCK 2002-29) showed only partial dominance of non-
determinate (NDT) growth habit (of IPCK 2002-29) over the determinate (DT) habit (of BGD
9971). However, the second cross (BGD 9971 × JG 16) indicated complete dominance of
NDT (JG 16) over the DT type (BG 9971); the F 2 generation showed a 15 (NDT):1 (DT) ratio,
showing duplicate gene action for growth habit in chickpea. The same was confirmed in the
randomly selected F 3 progenies also. During 2018-19, a total of 4 DT F 6 progenies derived
from the cross (BGD 9971 × IPCK 2002-29) were grown and assessed in preliminary trial for
yield and other attributes. Based on their performance over the check (IPCK 2002-29), two
superior lines, viz. RCECK 17-2 and RCECK 17-4, were selected for further evaluation. The
‘RCECK 19-4’ significantly outyielded (1852 kg/ha) the check ‘IPCK 2002-29’ (1513 kg/ha).
In lentil, a segregating population derived from a cross (ILWL 118 × DPL 58) was also
advanced, and 16 single plant selections (SPS) were performed based on biomass,
earliness and no. of pods. Further selections in succeeding generations resulted in the
identification of a super early genotype ‘RCEL 19-1’ in the year 2019-20. Besides super
earliness, this genotype when evaluated in wilt-sick nursery showed greater mortality than
the susceptible check ‘Seohore 74-3’, making it a suitable susceptible check for assessing
wilt reaction of test genotypes in the pathological trials. These two novel genotypes, viz.
‘RCECK 17-4’ (chickpea) and ‘RCEL 19-1’ (lentil), hold promise to be registered as useful
genetic stocks for further utilization in breeding programmes.
