Aegilops cylindrica species (CCDD, 2n = 4x = 28) is one of the wild relatives of wheat and hence known as a valuable source of genes related to biotic and abiotic stress tolerance. In this study genetic variation of 66 Aegilops cylindrica genotypes collected from west and northwestern of Iran was evaluated using quantitative and qualitative morphological traits. The results indicated that glume...
Improving the drought tolerance of barley varieties through the integrated efforts of plant biotechnology and conventional breeding is an important objective in barley breeding. One hundred and fifty eight doubled haploid lines of barley were mapped with 50 SSR and 93 AFLP markers. Agronomic traits such as early growth vigor, plant height, peduncle length, extrude of spike from flag leaf, spike...
In order to study of the grain yield and its components in spring wheat genotypes affected by resources limitation under optimum condition, an experiment was conducted using split plot experiment in RCBD design with three replications in Agricultural and Natural Resources Research Center of Khouzestan-Iran in 2010-2011 cropping season. In this study, main plot were consists of six wheat spring ...
As the main pigment in photosynthesis, chlorophyll significantly affects grain filling and grain weight of crop. Cytokinin (CTK) can effectively increase chlorophyll content and chloroplast stability, but it is irreversibly inactivated by cytokinin oxidase (CKX). In this study, therefore, twenty-four pairs of primers were designed to identify variations of wheat CKX (Tackx) genes associated wit...
Efficient use of space and high yields are critical for long-term food production aboard the International Space Station. The selection of a full dwarf wheat (less than 30 cm tall) with high photosynthetic and yield potential is a necessary prerequisite for growing wheat in the controlled, volume-limited environments available aboard long-term spaceflight missions. This study evaluated the phot...
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...
tall fescue is a cool season grass widely distributed and adapted to different environmental conditions of iran. superior seed-yielding potential of the plant is an important criterion during the seed reproduction phases of breeding new cultivars and as well under commercial seed production conditions. in order to evaluate germplasm and investigate the pattern of genetic variation of seed trait...
