“…Similarly, in chickpea contradictory results have been reported (e.g. Sabaghpour et al, 2003;Toker and Canci, 2007;Gaur et al, 2008;Zaman-Allah et al, 2011b). Therefore, it can be concluded that optimal plant leaf area development depends on environment under consideration and its water availability pattern.…”

Chickpea is cultivated at the end of the rain in tropical and sub-tropical regions like in India. Crop growth depends on the soil moisture contained in the soil profile, commonly leading to terminal water deficits. The past three decades of research have focused on improving rooting traits, with a particular focus on the speed of root extension in the soil, making the assumption that this would lead to more water extraction. Here, we used a robust crop simulation model to assess genetic and management modifications that would affect water availability to the crop. Against expectations, increasing the rate of depth of root extension to 30 mm day -1 from a baseline of 17 mm day -1 , to reflect the characteristics of an existing root trait QTL on linkage group 5 of chickpea, brought about a yield penalty in all situations (4-6%), especially in locations where the in-season rainfall was low (up to a 15% yield penalty). By contrast, modifying soil characteristics by increasing the depth of effective water extraction from 1000 mm to 1200 mm led to yield increases in all situations (8-12%) as a result of greater water available at the end of the growing season. Changing the rate of leaf area development rate associated with the root QTL locus on LG5, had no impact on yield except for a yield increase at the two highest yielding locations. The greatest changes in yield were obtained by irrigating the crop with 30 mm at R5. The average yield gain across all locations was 29% and the high yield benefit was achieved across all yield levels. These results indicated that some benefit would come from growing the crop in soil with a higher depth of effective water extraction, which may require faster root growth in very low rainfall environments, but the greatest yield benefit would result from modest irrigation at R5.

The chickpea (Cicer arietinum L.) is usually grown under rainfed, rather than irrigated conditions, where drought accompanied by heat stress is a major growth constraint. The aim of this study was to select chickpea genotypes having resistance to drought/heat stress and to identify the most appropriate selection criteria for this. A total of 377 chickpea accessions were sown 2 months later than normal for the Antalya region (Turkey) to increase their exposure to the drought and high‐temperature conditions of a typical summer in this part of the world. Interspersed between every 10 test genotypes as benchmark genotypes, were plants of the two known genotypes ILC 3279 (drought‐susceptible) and ILC 8617 (drought‐susceptible), while ICC 4958 (known drought‐resistant) and ICCV 96029 (known very early, double‐podded) were also sown for confirmation. All plants were subsequently screened for drought and heat stress resistance. Soon after the two known susceptible genotypes had died, evaluations of the entire trial were made visually on a scale from ‘1’ (free from drought/heat damage) to ‘9’ (all plants died from drought/heat). Yield loss in many of the test genotypes and in the two known susceptible genotypes (ILC 3279 and ILC 8617) rose to 100 %. The desi chickpeas (smaller, dark seeds) were generally more drought‐ and heat‐resistant than the kabuli chickpeas (larger, pale seeds). Two desi chickpeas, ACC 316 and ACC 317, were selected for drought and heat (>40 °C) resistance under field conditions. Seed weight was the trait least affected by adverse environmental conditions and having the highest heritability, and it should be used in early breeding selections. When breeding drought‐ and heat‐resistant chickpeas, path and multivariate analyses showed that days to the first flowering and maturity to escape terminal drought and heat stresses should be evaluated ahead of many other phenological traits, and harvest index, biological yield and pods per plant for increased yield should also be considered.

“…Improvements of chickpea yields under DS have been achieved, mostly by breeding short duration cultivar that mature before the water deficit becomes too severe (Kumar et al 1985;Kumar and Rao 2001) with an often observed penalty in grain yield due to underutilisation of the available growing season. To overcome this self-imposed penalty, relatively longer (medium) duration chickpea cultivars have to be improved either though drought avoidance or tolerance mechanisms (Sabaghpour et al 2003).…”

Abstract. Chickpeas are often grown under receding soil moisture and suffer~50% yield losses due to drought stress. The timing of soil water use is considered critical for the efficient use of water under drought and to reduce yield losses. Therefore the root growth and the soil water uptake of 12 chickpea genotypes known for contrasts in drought and rooting response were monitored throughout the growth period both under drought and optimal irrigation. Root distribution reduced in the surface and increased in the deep soil layers below 30 cm in response to drought. Soil water uptake was the maximum at 45-60 cm soil depth under drought whereas it was the maximum at shallower (15-30 and 30-45 cm) soil depths when irrigated. The total water uptake under drought was 1-fold less than optimal irrigation. The amount of water left unused remained the same across watering regimes. All the drought sensitive chickpea genotypes were inferior in root distribution and soil water uptake but the timing of water uptake varied among drought tolerant genotypes. Superiority in water uptake in most stages and the total water use determined the best adaptation. The water use at 15-30 cm soil depth ensured greater uptake from lower depths and the soil water use from 90-120 cm soil was critical for best drought adaptation. Root length density and the soil water uptake across soil depths were closely associated except at the surface or the ultimate soil depths of root presence.
