“…Our results showed that terminal drought decreased a drastic reduction in root traits and yield in both years and the magnitude of reduction would depend on peanut genotypes (Tables 5 and 6). These results supported previous finding that pod yield were reduced when peanut was subjected to terminal drought (Boontang et al, 2010;Girdthai et al, 2010) and the reduction also varies among peanut genotypes (Harris et al, 1988). Drought related reduction in growth and yield of plants could be ascribed to stomatal closure in response to low soil moisture, which decreased the intake of CO2 and, as a result, photosynthesis decreased (Cornic, 2000;Flexas et al, 2004).…”

“…Terminal drought stress is typical of end season where the crop grows and matures on a progressively depleting soil moisture profile. Previous studies indicated that drought during the vegetative phase has small effect on growth and yield of peanut (Awal and Ikeda, 2002), and 24% of yield reduction was reported when peanut was subjected to drought during the end of growing season (Boontang et al, 2010;Girdthai et al, 2010).…”

Drought at pod filling reduces growth, yield, and seed quality of peanut (Arachis hypogaea L.) Great root system can reduce yield loss under water stress. There is a lack of information on root traits for peanut genotypes and the relationship between rooting traits and peanut yield under terminal drought. The pot experiments were conducted at Khon Kaen University, Thailand, in 2004Thailand, in -2005Thailand, in and 2005Thailand, in -2006. A randomized complete block design was used with two factorials set-up with four replicates. Factor A consisted of two water regimes (field capacity and 1/3 available water at 80 d after planting to harvest), and factor B comprised of 11 peanut genotypes. Data were recorded for root traits (root dry weight, root length, root surface, root diameter, and root volume), and peanut yield (pod dry weight, biomass, and harvest index) were measured at final harvest. Terminal drought significantly decrease root characteristics (0.83-1.03 g plant -1 of root dry weight) and peanut yield (7.98-8.89 g plant -1 of pod dry weight). Yield responses to terminal drought were not correlated with root traits except root length and root volume (r = 0.71** and 0.83**, respectively). Some genotype, root traits seem to be correlated with peanut yield under terminal drought. 'KK60-3' showed high root traits, maintained pod dry weight under terminal drought, whereas Tifton 8 maintained biomass production. ICGV98348 had high root traits, maintained pod dry weight and harvest index under drought conditions. The results suggested that peanut contained high root characters which maintained yield under terminal drought.

“…In this study, intermittent drought stress decreased significantly the pod and haulm weight. Previous findings reported that pod and haulm yields decreased when groundnut was subjected to drought stress [8,10,21,22]. Our findings showed a negative relationship between pod and haulm weight under WS conditions and indicated that, in response to drought, tolerant genotypes produced much pods and less biomass.…”

Investigation of groundnut genotypes response to drought stress could contribute to improving drought tolerance and productivity. The objective of this study was to investigate new improved groundnut varieties response to drought stress under controlled conditions to identify tolerant materials and drought tolerance related traits. Thus, three experiments were conducted during off-seasons: two experiments in lysimetric system in 2017 and 2018 and one experiment in pots in 2017, to assess twelve varieties in a randomized complete block design with 2 water regimes and 4 replications. The water regimes were a full irrigation (WW) and an intermittent drought imposed at flowering times (WS). The investigated morphophysiological traits like transpiration, specific leaf area, root dry matter, root length density, and yield components decreased under WS. Significant year effect and genotypic variation were observed on most of investigated traits. Genotypes ICGV 92206 and ICGV 06319 showed low transpiration and revealed high pod yielding and early maturing genotypes under both water regimes, while genotypes ICGV 92035, ICGV 92195, ICGV 02038, ICGV 07211, and ICGV 07210 were drought-sensitive for pods production but produced high haulm under both water regimes. ICGV 92206, ICGV 02005, ICGV 02125, and ICGV 06319 showed higher yielding than 55-437 and Fleur 11. In this study, low total transpiration to control water loss, chlorophyll content, and root length density revealed drought tolerance associated traits for pod production, while TTW, TE, RDW, and RV revealed drought tolerance associated traits for fodder production.

“…These results are in conformity with previously published results of (Thakur et al, 2013 [40] , Hamidou et al, 2012 [18] ). Previous studies also reported over significant genotypic differences for RWC (Clavel et al, 2006) [10] , Bootnang et al 2010) [7] , SCMR (Upadhya et al, 2011 [43] , Babita et al, 2006 [3] , Nigam et al, 2005 [29] , Nigam and Aruna, 2008 [28] , and Sheshshayee et al, 2006 [36] ), pod yield (Puangbut et al, 2009, 2010 [32,33] and Jongrungklang et al, 2008 [20] ), root to shoot ratio (Thakur et al 2011) [41] , and MSI (Pranusha, 2011) [31] . The remarkable variation in RWC under stressful and stressfree environments could be the result of higher leaf temperature and declined soil moisture availability in root zone of stressed plants (Shinde et al, 2010) [37] .…”

Groundnut is one of the leading oilseed crops, primarily cultivated for edible oil and protein in arid and semi-arid regions of the world. Drought is the most significant constraint that severely affects the pod yield and growth related traits in groundnut. The present study aims at assessing the genetic variability in groundnut genotypes to terminal drought tolerance The forty groundnut genotypes including advanced breeding lines and existing cultivars were evaluated under irrigated and drought stress conditions during Rabi 2016-17 at the College of Horticulture, Hiriyur using two sets of randomized completely block design with two replications. The results revealed the highly significant differences for all traits studied among the genetic stock indicating the remarkable levels of variability existed among the investigated genetic material that are very essential in groundnut improvement for terminal drought tolerance. The genotypes SB-14, ICGV 15141 and ICGV 15145 were observed better for terminal drought tolerance with high pod yield. It is suggested that these genotypes could be grown under regions of limited rainfall and may be used as parents in breeding programs for developing drought tolerant groundnut cultivars.
