Genotypic variation in sorghum [Sorghum bicolor (L.) Moench] exotic germplasm collections for drought and disease tolerance
Sorghum [Sorghum bicolor (L.) Moench] grain yield is severely affected by abiotic and biotic stresses during post-flowering stages, which has been aggravated by climate change. New parental lines having genes for various biotic and abiotic stress tolerances have the potential to mitigate this negative effect. Field studies were conducted under irrigated and dryland conditions with 128 exotic ge...
متن کاملEvaluation of yield of promising dual purpose grain- forage sorghum lines (Sorghum bicolor L. Moench) using drought tolerance indices
To evaluate and select the promising lines of dual purpose grain-forage sorghum under drought stress conditions, a field experiment assplit plot arrangements in randomized complete block design with three replications was carried out atresearch field station of Seed and Plant Improvement Research Institute, Karaj, Iran, in 2014 and 2015 growing seasons. Irrigation levels (60 mm, 120 mm and 180 ...
متن کاملEvaluation of grain sorghum (Sorghum bicolor L.) lines/cultivars under salinity stress using tolerance indices
Selecting and cultivating the crops/varieties that can tolerate water salinity is potentially animportant strategy to save fresh water resources and maximize the crop yield in salt affected areas.To evaluate the responses of 36 sorghum lines and cultivars to salinity stress, two fieldexperiments were conducted in non-stress (EC=2 dS/m) and salinity stress conditions (EC=12dS/m) using randomized...
متن کاملMapping of QTLs underlying flowering time in sorghum [Sorghum bicolor (L.) Moench]
Due to its critical importance in crop yield, the photoperiodic regulation of flowering time is considered an important trait in sorghum breeding programs. In this study, quantitative trait loci for flowering time were detected using an F(2) population derived from a cross between Kikuchi Zairai, a late-flowering cultivar originating from Japan and SC112, an early-flowering cultivar originating...
متن کاملSelection indices to identify drought-tolerant grain sorghum cultivars.
Twenty-five cultivars of grain sorghum [Sorghum bicolor (L.) Moench] were examined under both drought stress and normal conditions in 4 experiments. In each condition, genotypes were evaluated in a factorial experiment using a randomized complete block design with 3 replications. Eight drought tolerance indices including stability tolerance index, mean productivity (MP), geometric MP, harmonic ...
