Groundnut yield in rain fed areas has been limited by drought stress because pod yield and other growth parameters have been severely affected. The aim of this study is to evaluate the genetic variability, character association and path analysis between yield and its contributing traits in 30 groundnut genotypes under drought. Drought tolerant groundnut variety ICGV , released in India for cultivation in drought-prone district Anantapur, which has world’s largest groundnut-growing area of about , ha in a district, has resulted in increase in net income by 36 and 30% reduction in year-to-year yield variability for farmers in the district (Birthal et al.
CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Groundnut is a major cash crop in the semi-arid tropics, where it is grown mainly under rainfed conditions. As rainfed condition is characterized by low, irratic and unassured rainfall, creates drought condition at any stage of the crop growth. The occurrence of drought is considered as a major factor for limiting the. increase the efﬁciency of crop improvement in drought-prone environments. Introduction The International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)’s man-date crops, i.e. pearl millet (Pennisetum glau-cum), sorghum (Sorghum bicolor), chickpea (Cicer arietinum), groundnut (Arachis hypogaea) and pigeonpea (Cajanus cajan), are.

Sclerotium rolfsii is a major constraint for production in most of the groundnut growing areas in India inflicting % yield losses annually. Irrigated groundnut grown in post-rainy and summer seasons in India is often infected. drought conditions, and they suggested that these geno-types possessed drought avoidance traits. However, the direct assessment of deep rooting, RLD and root distribu-tion of peanut genotypes under different water regimes to see how peanut genotypes respond to drought in term of these traits has not been clearly demonstrated.

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 Author: Achirou Bacharou Falke, Achirou Bacharou Falke, Falalou Hamidou, Falalou Hamidou, Oumarou Halilou, A.
Fifty genotypes of groundnut including released varieties and advanced breeding lines were used to assess the drought tolerance. These genotypes were evaluated both in managed drought stress (DS) and non stress (NS) situations during post rainy season (Jan-April), at Oilseeds Farm, Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu, : S.

They are combined with meteorological data to simulate yields by location. Efficient genotypes are identified by several risk criteria. Genotype rankings based on these risk criteria and simulated yields are. The extent of yield loss due to drought in groundnut is depends on duration and intensity of drought (Thakur et al., , Nigam et al.
) and the crop growth stage at which drought. The present experimental study aimed to determine the morphophysiological and anatomical responses of groundnut genotypes Kadiri 9, Narayani, Dharani, JL24, TPT-3 and Kadiri 6 under drought stress.
In India, out of the total million ha rainfed rice area, approximately million ha lies in eastern India (Singh and Singh, ), of which million ha of upland and million ha of lowland area are drought-prone (Pandey and Bhandari, ).
Similarly, drought is a severe problem in rainfed areas of the southern Indian states of. A groundnut germplasm ( genotypes) was evaluated in four trials over a period of two years, under intermittent drought and fully irrigated conditions. Two trials were exposed to moderate temperature during the rainy season while the two others were subjected to high temperature during summer.
The objectives were to segregate the components of the genetic variance and their interactions with. Drought-associated phenotypic traits and their interrelationships in barley.
Drought-tolerant crop cultivars resist crop yield losses in drought-prone areas. Thus, deep understanding of pertinent drought-tolerance-associated agronomic traits and of their interrelationships in target environments is indispensable to cultivar development.

An evaluation trial with sixty-two groundnut genotypes comprised of advanced breeding lines, popular varieties and germplasm lines was conducted in Alfisols (Alfisol-Patancheru Soil Series; Udic Rhodustolf) fields at ICRISAT, Patancheru, India (at ° N latitude and.
groundnut genotypes having lower SLA (high TE) showed more stability in dry matter production under drought. It has recently been shown that a handheld portable SPAD chlorophyll meter can be used effectively following necessary protocols for rapid assessment of.
Background: Groundnut (Arachis hypogaea L.) productivity is very low in the Sahel mainly because of drought caused by low and erratic rainfall. End-of-season drought is the most important factor limiting groundnut production in the Sahel. Identification of genotypes that have a greater ability to use limited available water is important to enhance productivity of the crop.
Drought tolerant groundnut variety ICGVreleased in India for cultivation in drought-prone district Anantapur, which has world’s largest groundnut-growing area of aboutha in a district, has resulted in increase in net income by 36 and 30% reduction in year-to-year yield variability for farmers in the district (Birthal et al.
groundnut in study period was yield followed by price (%) and area effect (%) (Murlidhar et al. ).The world annual groundnut production is around million tons, in India it is grown an about m ha and a productivity of t per hectare(). In Karnataka it is grown in an area of about m ha with the. Anantapur is a drought-prone district in the rain shadow area of Andhra Pradesh, India.
Despite frequent droughts and crop failures, over 70% of the cultivated area in the district (~ million ha) is sown to groundnut each year (Figure 1).

The genotypes ‘Banglami’, ‘Bizor’, ‘Bizor-2’, ‘Horin Kajuli’ and ‘Raja Ahu’ genotypes were the best genotypes of the P2 population for drought tolerance and high recovery rate.

Introduction. Groundnut (Arachis hypogaea L.) or peanut, an important oilseed and food legume crop, is cultivated in million ha world over with a total production of million tons during (Food and Agriculture Organization of United Nations, ).China and India are the leading groundnut producers followed by USA and Nigeria.

The project aims to improve the livelihoods of smallholder farmers in the drought-prone areas of Sub-Saharan Africa (SSA) and South Asia (SA) through improved productivity and production of six major grain legumes – chickpea, common bean, cowpea, groundnut, pigeonpea and soybean.The genotypes were tested in five moisture levels.
The results revealed that under severe moisture deficits (+ to %), TMV-2 recorded the highest yield followed by ICGV-ICGV, R, GPBD-4, Dh and ICGV were found to be drought .
