Combining ability effects were estimated for different agronomic characters in line × tester crossing program comprising 21 hybrids produced by crossing 7 lines and 3 testers. Parents and hybrids differed significantly for general combining ability (GCA) and specific combining ability (SCA) effects, respectively. The variance due to GCA and SCA showed that gene action was predominantly additive...

Purpose and Objectives. Our purpose was to study the inheritance of spike productivity elements by F1 hybrids from tester crosses winter bread wheat varieties different geographical origins.
 Materials Methods. Twenty hybrid combinations were studied. Field studies conducted in 2017–2019. The experiments laid out accordance with requirements breeding field experiments. their parents sown a...

the new cereal, primary tritipyrum lines, is an artificial hexaploeid wheat (2n=6x=42, aabbebeb) from crossing between triticum durum (2n=4x=28, aabb) and thinopyrum bessarabicum (2n=2x=14, ebeb) species. in this study the salt tolerant potencial of new primary tritipyrum lines for nacl (0, 100, 200 mm) in an hydroponic experiment was studied in a completely randomized split plot design with th...

to study the effect of sowing date and a single irrigation (si) on yield and yield components of barley, a field experiment was conducted in dryland agricultural research institute (maragheh, iran) in 2004-06 cropping seasons, using a split plot based on a randomized complete block design with 3 replications. main plots were assigned to 3 levels of sowing date (early, normal and late). sub-plot...

to evaluate of quantitative and qualitative yield of two basil (ocimum basilicum l.) medicinal plants as affected by planting pattern and plant density, an experiment carried out in factorial arrangement basis on randomized complete block design with three replications. two varieties (green and purple) of basil, two planting patterns (single and double row) and four plant densities (40, 60, 80 ...

abstract to assay the effect of acetylsalicylic acid pretreatment on enhancement of yield and yield components of barley (reihan-03) under water stress condition, an experiment was conducted as a spilt-plot arrangement based on randomized complete block design with four replications at the research field of shahid bahonar university of kerman, iran, in 2012-2013. irrigation condition was arrang...

Spike-related traits such as spike length (Sl), fertile spikelet number (Fsn), sterile spikelet number (Ssn), grain number per spike (Gns), and thousand-kernel weight (Tkw) are important factors influencing wheat yield. However, reliably stable markers that can be used for molecular breeding in different environments have not yet been identified. In this study, a double haploid (DH) population ...
