Description Among the various cool season pulses grown in India, chickpea
(Cicer arietinum L.) occupies an important position in rainfed
agriculture. Chickpea is largely grown (>67% area) on conserved/
residual moisture, contributing about 45% to the total
pulses production in India. Being a rainfed crop, it often faces
terminal drought stress. When chickpea sowing is delayed in
fields vacated by paddy in the presence of terminal heat, soil
moisture stress further limits its productivity. This necessitates
the adoption of suitable strategies to alleviate per se drought
tolerance in chickpea. Two main strategies, integrated breeding
and transgenic technology, have been adopted for developing
drought-tolerant varieties. The third potential strategy is
utilization of nanotechnology, which has not been tried under
Indian NARES. Systematic breeding efforts resulted in development
of varieties having per se drought tolerance (RSG 44, Vijay,
RSG 888, JG 74, Pusa 2024), and escape (JG 11, JG 16, JSC
56, IPC 2006-77 etc.) exploiting earliness. QTLs responsible
for drought tolerance have been identified in chickpea genotype
ICC 4958, which have been transferred, and drought-tolerant
elite breeding lines have been developed. MAGIC and
NAM populations combining drought and heat tolerance are
now becoming available for identification of elite breeding lines
having combined tolerance to both stresses for their possible
release. Exploitation of transgenic technology using DREB
gene has also shown promise. The use of nano-particles in enhancing
root development and growth vigour in chickpea has
opened the doors for exploitation of nanotechnology for alleviation
of per se drought tolerance.
