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 کاملGenotypic variation in drought tolerance of poplar in relation to abscisic acid.
We investigated effects of water stress and external abscisic acid (ABA) supply on shoot growth, stomatal conductance and water status in 1-year-old cuttings of a drought-sensitive poplar genotype Populus x euramericana cv. I-214 (Italica) and a drought-tolerant genotype P. 'popularis 35-44' (popularis). Populus popularis was more productive and maintained higher leaf water potentials throughou...
متن کاملGenotypic Variation for Salinity Tolerance in Cenchrus ciliaris L.
Scarcity of irrigation water and increasing soil salinization has threatened the sustainability of forage production in arid and semi-arid region around the globe. Introduction of salt-tolerant perennial species is a promising alternative to overcome forage deficit to meet future livestock needs in salt-affected areas. This study presents the results of a salinity tolerance screening trial whic...
متن کاملinvestigation on salt tolerance and chromosomal variation in cell culture of sugar beet (beta vulgaris l.)
effects of culture medium containing hormonal compositions on phenotypic and chromosomal variations of sugarbeet cultured tissues were examined. experiments were carried out in different nacl levels. cytological studies were conducted on calli originated from suspension culture. hypocotyl of seven day old seedlings of the two diploid lines were cultured in ms medium containing hormonal composit...
متن کاملStudy of Genetic Variation and Drought Tolerance in Commercial Rapeseed (Brassica napus L.) Cultivars
In order to identify drought stress tolerance in rapeseed, nine commercial rapeseed cultivars (Opera, Karaj1, Karaj2, Karaj3, Zarfam, Okapi, Talayeh, Licord and Modena) were evaluated under two conditions (normal and drought stress) in Kangavar region in the west Iran in 2014-2015 growing season. This research was carried out in a split plot experiment based on completely randomized design in f...
