“…comm.). We speculate that there might be some particular steps in the reproductive development that make desi chickpea better suited than kabuli to cope with abiotic stresses such as drought and salinity that share some commonalities (Leport et al, 2006). That particular step could be equally affected by water deficit and salt stress.…”

“…One drawback in these previous studies was that genotypes were assessed for salinity tolerance based on vegetative biomass and not on seed yield. Knowing the high sensitivity of reproductive stages to abiotic stresses (Boyer and Westgate, 2004;Leport et al, 2006), we raise the question here whether the success of a genotype under salinity is bound to the reproductive success under that stress.…”

Salinity is an ever-increasing problem in agriculture worldwide, especially in South Asia (India, Pakistan) and Australia. Improved genotypes that are well adapted to saline conditions are needed to enhance and sustain production in these areas. A screening of 263 accessions of chickpea, including 211 accessions from ICRISAT's mini-core collection (10% of the core collection and 1% of the entire collection), showed a 6-fold range of variation for seed yield under salinity (1.9 L of 80 mM NaCl per 7.5 kg Vertisol), with several genotypes yielding 20% more than a previously released salinity tolerant cultivar. The range of variation in yields under salinity was similar in both kabuli and desi chickpeas, indicating that breeding for salinity tolerance can be undertaken in both groups. A strong relationship (r 2 = 0.50) was found between the seed yield under salinity and the seed yield under a non-saline control treatment, indicating that the seed yield under salinity was explained in part by a yield potential component and in part by salinity tolerance per se. Seed yields under salinity were therefore computed to separate the yield potential component from the residuals that accounted for salinity tolerance per se. Among the genotypes evaluated, desi genotypes had higher salinity tolerance than kabuli genotypes. The residuals were highly correlated to the ratio of seed yield under salinity to that of the control, indicating that both parameters can be used to assess salinity tolerance. A similar ratio was calculated for shoot dry weight at 50 days after sowing. However, no significant correlation was found between the shoot dry weight ratio and the yield ratio, indicating that differences in salinity tolerance among genotypes could not be inferred from measurements in the vegetative stage. The major trait related to salinity tolerance was the ability to maintain a large number of filled pods, whereas seed size was similar in tolerant and sensitive genotypes. Salinity tolerance was not related to the shoot Na + or K + concentrations. #

“…The drought tolerance in their case was found to be directly proportional to deep root system and high leaf water potential (LWP). High temperature stress also causes yield losses because of damage to reproductive organs (Anyia and Herzy, 2000) and had reduced total dry matter and grain yield during drought (Leport et al, 2006). Singh et al (1997), Kashiwagi et al (2005) and Lopez et al (2006) have screened out some pulses germ plasm accessions with greater genetic variability in various traits.…”

Drought is a major abiotic constraint limiting the chickpea yield up to a greater level in Pakistan. The yield level remain very low under prolong moisture deficit conditions. A set of 40 chickpea lines including some approved varieties were assessed for drought tolerance under glasshouse conditions. The crop was given an artificial drought stress at pre-flowering stage for a period of 30 days and then re-irrigated regularly till harvesting. The observations were recorded on plant wilting-I, plant wilting-II, crop recovery percentage and grain yield. The results revealed a relatively divergent response of various chickpea lines/varieties for all the studied parameters. Genotypes SL-05-30 NCS950219 and F-97-112 C remained superior while observing plant wilting-I by scoring 1, 1.67 and 2.00 at 1-9 rating scale and produced higher yield of 18.43, 18.33 and 18.23 grams per plant respectively. The plant recovery response revealed that more than 50% of studied lines could not properly recover after termination of moisture stress suggesting that moisture stress at pre-flowering has usually lethal effect on chickpea plants. Kabuli type chickpea lines were more sensitive to moisture stress and high temperature and produced lower yields as compared to desi type chickpea.
