Evaluation of drought tolerance in rice (Oryza sativa L.) cultivars and recombinant inbred lines
In order to study the adaptation of rice lines to drought stress and to identify the tolerant and sensitive lines, 150 pure lines in RIL population each derived from a cross between two Iranian rice varieties Gharib and Sepidroud were investigated. Augment design based on the randomized complete block design (RCBD) was used with 6 check cultivars and 4 replications in 2013-2014 growing season. ...
متن کاملEvaluation of Agronomic Traits and Drought Tolerance of Safflower Lines Derived from Three Inter-Specific Crosses
Due to genetic erosion over evolution events, the genetic diversity of domesticated safflower species for drought tolerance is limited. Wild species has been considered as useful genetic resources for improvement of abiotic stress tolerance. In this study, a cultivated species (C. tinctorius) was crossed by two wild species (C. palaestinus and C. oxyacanthus) and the genotypes were purified unt...
متن کاملstudy of drought tolerance indices in maize inbred lines under limited irrigation and normal conditions
abstract in order to genetic investigation of drought resistance indices, on 25 maize inbred lines, an experiment was conducted under three irrigation regimes; normal irrigation, limited vegetative irrigation and limited reproductive irrigation. in the limited vegetative irrigation, tol (stress tolerance) index had the highest phenotypic and genotypic coefficient of variation (83.83% and 68.04%...
متن کاملDetermination of levels of Striga germination Stimulants for maize gene bank accessions and elite inbred lines
Parasitism by Striga hermonthica (Del) Benth is a severe constraint in maizeproduction in sub-Saharan Africa. Varying levels of tolerance to Striga attack havebeen identified and exploited in breeding programs of several crops. However, thelevel and stability of the tolerance is generally unacceptable in field-practice. Onlylimited exploration has been undertaken among the farmers’ landraces to...
متن کاملMolecular and physiological approaches to maize improvement for drought tolerance.
Average maize yields have increased steadily over the years in the USA and yet the variations in harvestable yield have also markedly increased. Much of the increase in yield variability can be attributed to (1) varying environmental stress conditions; (2) improved nitrogen inputs and better weed control; and (3) continuing sensitivity of different maize lines to the variation in input supply, ...
