Abstract Chlorophyll stability during drought might be a promising criterion for selection resistance in peanut. The study describes two field trials conducted at Khon Kaen University, Thailand which investigate genotype × interactions wide range of peanut germplasm general and assess the relationship between chlorophyll genotypic performance particular, under drought. Two experiments (during 2003/2004 2004/2005 dry seasons) were split plot design with three water regimes [field capacity,...

Abstract The ability of a plant to modify its root distribution exploit deeper stored soil water may be an important mechanism avoid drought. This study aimed at assessing distributions, variations in length density (RLD) and percentage distribution, the relevance traits for yield drought‐resistant peanut genotypes under different available levels. experiment was conducted dry season during years 2003/04 2004/05. Eleven (ICGV 98300, ICGV 98303, 98305, 98308, 98324, 98330, 98348, 98353,...

Arbuscular mycorrhizal fungi (AMF) and phosphate solubilizing bacteria (PSB) could interact synergistically because PSB solubilize sparingly available phosphorous compounds into orthophosphate that AMF can absorb transport to the host plant. Little is known about interactions between these two groups in terms of promoting Jerusalem artichoke, Helianthus tuberosus L., which widely planted by farmers its high inulin content. Production depends mainly on synthetic fertilizers as source plant...

Abstract The relationship between biomass production and N 2 fixation under drought‐stress conditions in peanut genotypes with different levels of drought resistance is not well understood. objective this study was to determine the effect on by evaluating relative values these two traits watered water‐stress conditions. Twelve were tested field dry seasons 2003/2004 2004/2005 north‐east Thailand. A split‐plot design four replications used. Main‐plot treatments three water regimes [field...

Inheritance of traits is important for developing effective breeding schemes improving desired traits. The aims this study were to estimate the heritabilities ( h 2 ) drought resistance and genotypic r G phenotypic P correlations between agronomic traits, examine relationships under stressed nonstressed conditions. 140 lines in F 4:7 4:8 generations from four peanut Arachis hypogaea L.) crosses tested field capacity (FC) two‐thirds available soil water (2/3 AW) two experiments. Data recorded...

With 1 figure and 4 tables Abstract Terminal drought induces preharvest aflatoxin contamination (PAC) in peanut. Drought resistance traits are promising as indirect selection tools for improving to PAC. The objectives of this study were determine the effects terminal on PAC investigate associations between surrogate tolerance Field tests under rainout shelters conducted dry seasons 2004/2005 2005/2006. Eleven peanut genotypes evaluated irrigated conditions. Data recorded physiological...

Details on growth and yield for cassava planted different dates are useful determining suitable genotypes particular growing seasons. Our aim was to study of dates. Four (Kasetsart 50, Rayong 9, 11 CMR38-125-77) were evaluated using a randomized complete block design (RCBD) with four replications in six periods (20 Apr, 25 May, 30 June, 5 Oct, 10 Nov 15 Dec 2015-2016) at Khon Kaen, Thailand. Soil properties determined prior planting, crop traits weather data recorded. The planting had...

Summary Groundnut as a pre‐rice crop is usually harvested 1–2 months before rice transplanting, during which much of legume residue N released could be lost. Our objectives were to investigate the effect mixing groundnut residues (GN, 5 Mg ha −1 ) with straw (RS) in different proportions on: (i) regulating dynamics, (ii) potential microbial interactions decomposition, and (iii) associated nitrous oxide methane emissions at weekly intervals lag phase until transplanting (i, ii) or harvest...

Abstract Drought during the pre‐flowering stage can increase yield of peanut. There is limited information on genotypic variation for tolerance to and recovery from drought (PFD) more importantly physiological traits underlying variation. The objectives this study were determine effects moisture stress phase pod understand some responses in response PFD. A glasshouse field experiments conducted at Khon Kaen University, Thailand. experiment was a randomized complete block design consisting...

Jerusalem artichoke (Helianthus tuberosus L.) is an important tuber crop. However, seeds contain high levels of starch and lipid, making the extraction high-quality RNA extremely difficult gene expression analysis challenging. This study was aimed to improve existing methods for extracting total from dry assess applicability improved method in other plant species. Five were evaluated on two modified. One modified with significant improvement applied assay diverse accessions, sunflower, rice,...

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 information on traits for genotypes the relationship between rooting terminal drought.The pot experiments were conducted Khon Kaen University, Thailand, in 2004-2005and 2005-2006.A randomized complete block design was used with two factorials set-up four replicates.Factor A consisted regimes (field capacity 1/3 available 80...
