Water stress reduces the yield of agricultural crops severely. The objectives of this study were to investigate genotypic differences between 20 popcorn lines in environments under wellirrigated (WW) and water stressed (WS) conditions to determine phenotypic, genetic and environmental relations among agronomic and root traits...

Maize hybrid stability in environments under water restriction using mixed models and factor analysis
Authors: A.O. Santos, J.J. Nuvunga, C.P. Silva, L.P.M. Pires, R.G. Von Pinho, L.J.M. Guimar�£es and M. Balestre
In several crops, the water deficit is perhaps the main limiting factor in the search for high yields. The objective of this study was to evaluate the phenotypic stability of maize hybrids in environments with and without water restriction using the analytical factor (AF) approach. We evaluated 171 maize hybrids in 14 environm.. Read More»

Genetic variability and expression of agro-morphological traits among genotypes of Coffea arabica being promoted by supplementary irrigation
Authors: W.N. Rodrigues, S.V.B. Brinate, L.D. Martins, T.V. Colodetti and M.A. Tomaz
The use of supplementary irrigation to sustain the plantation during moments of severe water stress or moments of high water demand is becoming almost a norm to keep sustainable crops, especially due to the climate changes and the high frequency in which climate extremes are occurring lately. The objective of this study was to.. Read More»

Genetic analysis of drought tolerance with respect to fiber traits in upland cotton
Authors: R.A. Nasimi, I.A. Khan, M.A. Iqbal and A.A. Khan
Cotton germplasm was analyzed to investigate its potential for developing water stress tolerance in varieties in the future. Four tolerant (NIAB-78, CIM-482, BH-121, and VH-142) and four susceptible (CIM-446, FH-1000, FH-900, and FH-901) lines were identified of 50 accessions based on their seedling root length. A complete set.. Read More»

Estimation of diversity and combining abilities in Helianthus annuus L. under water stress and normal conditions
Authors: M. Saba, F.A. Khan, H.A. Sadaqat and I.A. Rana
Sunflower cannot produce high yields under water-limiting conditions. The aim of the present study was to prevent the impediments on yield and to develop varieties with high-yield potential under water scarce conditions. For achieving this objective, it is necessary to detect parents with desirable traits that mainly depend on.. Read More»
