selection tolerant cultivars of wheat (as a strategic plant) under drought stress by using traits that are less affected by the environment, increases efficiencies. In this regard, in order to study some genetic parameters of physiological and agronomical traits and also genetic diversity in spring wheat cultivars under normal irrigation (control) and drought stress conditions in booting stage,...

drought stress is one of the most important environmental stresses that affect yield of bread wheat strongly. considering that the yield achieved with the interaction of a large number of plant traits and environment, so the morphological and agronomical traits, can serve as selection criteria under environmental conditions. by genetic analysis and estimation of inheritance and mode of gene act...

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...

Wheat yield is largely determined during the period prior to flowering, when the final numbers of fertile florets and grains per spike are established. The aim of this study was to assess the dynamics of floret primordia development in winter wheat in response to pre-anthesis application of a synthetic cytokinin, 6-benzylaminopurine (6-BA). We conducted an experiment in which two foliar spray t...

─This study was conducted to investigate the efficacy of five herbicides on narrow leaved weeds and growth and yield of wheat. An experiment was conducted at Agronomic Research Farm, University of Agriculture Faisalabad. The experiment was laid out in randomized complete block designee (RCBD) with three replications. Treatments studied were clodinafop (Topic-15 WG) at 37 g a.i. ha, clodinafop (...

    Present study aimed to assess the relationship between grain yield and its components in 116 rice genotypes in F₂ generations obtained from crosses between Tarom-Jelodar and 229R cultivars. Correlation analysis showed that the number of panicle per plant (0.758), the number of filled grains per panicle (0.604), the 100 grains weight (0.401) and grain width (0.234) had significant positive r...
