Wild relatives continue to evolve in nature, and live by a different rule than the crop plants – which is survival of the fittest. Wild species have evolved to survive droughts, floods, extremes of heat and cold, and have the capability to withstand damage by insect pests and diseases that cause heavy damage to cultivated species.any improved cultivars of crops are vulnerable to insect pests as they lack defense mechanism of their wild progenitors.

Androgenesis was observed in a wide cross of Cicer arietinum x C. pinnatifidum. Hybrids between C. arietinum x C. pinnatifidum were obtained after rescuing the hybrid embryos in vitro. The hybrids were initially devoid of any chlorophyll pigment and were albinos. Hybrid shoots were grafted onto chickpea rootstocks to obtain hybrid plant. None of the hybrid plants flowered. Flower buds were observed on the hybrid plants when 1 mg zeatin/litre was added.
Sixteen on-farm trials in 2002 and 9 trials in 2003 were conducted during the post-wet season in Kurnool, Andhra Pradesh, India, to demonstrate the beneficial effects of improved production technologies over farmers' practice. The improved technology package included improved chickpea cv.

ICCV 92318, a new kabuli chickpea cultivar developed from (ICCV 2 x Surutato) x ICC 7344, was selected for multilocation evaluation along with the controls DZ 10-4 (local cultivar) and Arerti (standard cultivar). The trials were conducted at 7 locations in Patancheru, Andhra Pradesh, India, during 1999/2000 and 2000/01 and at 4 locations during 2001/02. The overall average yield of ICCV 92318 was 2546 kg/ha against 2864 kg/ha for Arerti and 2093 kg/ha for DZ 10-4.

Greenhouse pot experiments were carried out in 2004 to check if there are any variations available for carbon isotope discrimination (d13C), to investigate the relationship between d13C and transpiration efficiency (TE), and to ascertain the possibility of using d13C as a surrogate for TE measurements. Ten chickpea genotypes (Annigeri, ICC 10448, ICC 13219, ICC 14199, ICC 1882, ICC 283, ICC 4958, ICC 5337, ICC 5680 and ICC 8261) with contrasting growth duration, type (desi or kabuli), growth habit and root system were used.

A study was undertaken to document the extent of variation available for the SPAD chlorophyll meter readings (SCMR) in the mini-core germplasm of chickpea and to identify the accessions with contrasting SCMR. The entire mini-core germplasm collection of C. arietinum (211 accessions) along with 5 genotypes (Annigeri, ICC 4958, Chafa, ICCV 2 and ICC 898) as references were evaluated by measuring SCMR in a precision Vertisol field in Patancheru, Andhra Pradesh, India, during the 2005/06 post-rainy season.
