screening for drought stress tolerance in cowpea genotypes )vigna unguiculata l (.
introduction drought stress is one of the most important abiotic stresses all around the world. the aim of breeding studies and breeding for resistance to drought is that breeders seek to identify varieties and genetic resources to drought resistant and comparison of drought resistance among the varieties and the introduction of superior varieties to farmers. drought or imbalance between supply...
متن کاملRecent advances in cowpea [Vigna unguiculata (L
After decades of research on cowpea, significant amount of omics datasets are available and useful in understanding the genetic relationship between Vigna unguiculata ssp. unguiculata and other species belonging to the same genus as well as its genetic variation. Besides, the development of genetic map allowed the chromosome localization of molecular markers associated with disease resistance, ...
متن کاملscreening for terminal drought stress tolerance in cowpea genotypes (vigna unguiculata l.)
in order to study and determine the most effective traits, drought tolerance indices and identify tolerant genotypes in terminal drought stress on the cowpea, an experiment was carried out based on an augment design in two separate conditions in the karaj farm, faculty of agriculture, tehran university in 2009. drought stress was imposed by cutting irrigation after flowering against normal irri...
متن کاملRadio-sensitivity of selected cowpea (Vigna unguiculata) genotypes to varying gamma irradiation doses
An appropriate dose of radiation should be established on target genotypes before large scale mutagenesis undertaken. The objective of this study was to determine an ideal dose of gamma radiation to induce genetic variation in selected cowpea (Vigna unguiculata) genotypes. Seeds of three Namibian released cowpea genotypes were gamma irradiated using seven dozes at the International Atomic Energ...
متن کاملToxic effects of Pb2+ on growth of cowpea (Vigna unguiculata).
A concentration as low as 1 microM lead (Pb) is highly toxic to plants, but previous studies have typically related plant growth to the total amount of Pb added to a solution. In the present experiment, the relative fresh mass of cowpea (Vigna unguiculata) was reduced by 10% at a Pb2+ activity of 0.2 microM for the shoots and at a Pb2+ activity of 0.06 microM for the roots. The primary site of ...
