Soil salinity poses considerable and increasing problems for agriculture, and is receiving much attention from plant breeders. The identification of genes whose expression enables plants to adapt to and/or tolerate salt stress is essential for breeding programs, but little is known about the genetic mechanisms of traits in saline conditions. The data obtained from 75 families produced by crossi...

to evaluate the growth regulatory effect of chlormequat chloride (ccc) under drought stress conditions on three barley cultivars, a field study was conducted under badjgah agro climatic conditions (altitude 1810 m, longitude 52° 46´, and latitude 29° 50´) during 2003-2004 growing season. a randomized complete block based split- split plot of four replications was employed with two moisture leve...

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 62(5): 945–952. Development of new bread wheat cultivars needs effi cient tools to monitor trait association in a breeding program. This investigation was aimed to charact...

the effect of late planting heat stress on yield and yield components was studied in 11 barley lines from icarda and one cultivar from iran (izeh) during two years (2005-2007) in gachsaran dry-land agricultural research station. each line was planted in a 6-rowed plot at two dates: normal planting (middle of november) and late planting (end of december) with three replications using a randomize...

BACKGROUND: Barley is one of the main important crops in the world, mainly used for animal feed and malt. OBJECTIVES: This study was conducted to evaluate the comparisons of seed yield and its components, phenological and physiological traits of different barley cultivars under Lorestan environmental condition. METHODS: Current rese...

breeding for drought stress is one the important purposes in wheat cultivars breeding programs. grain yield under drought stress is depended on phonological, morphological and physiological features. in order to investigate the general and specific combining ability and genes function under drought stress in three and two bread wheat lines and cultivars respectively, diallel one way cross was p...

Wheat grain yield consists of three components: spikes per plant, grains per spike (i.e. head or ear), and grain weight; and the grains per spike can be dissected into two subcomponents: spikelets per spike and grains per spikelet. An increase in any of these components will directly contribute to grain yield. Wheat morphology biology tells that a wheat plant has no lateral meristem that forms ...

Increasing grain yield potential in wheat has been a major target of most breeding programs. Genetic advance has been frequently hindered by negative correlations among yield components that have been often observed in segregant populations and germplasm collections. A tetraploid wheat collection was evaluated in seven environments and genotyped with a 90K SNP assay to identify major and stable...
