this study was performed for determine stability of the 18 promising barley lines and two check lines nosrat and mb-86-5 in six parts of the temperate zone including karaj, isfahan, birjand, varamin, zarghan and nishapur based on randomized complete block design)rcbd( with three replications and in two cropping seasons (2009-2011). following combined analysis, grain yield stability assessment w...

to determine the effects of different pollen types and suitable pollination time in medjhol date palm, an experiment was carried out with three pollen cultivars: ghaname, vardy and samesmave and two pollination times (1-3 days before or after spathe opening) during 2010-2011 in date palm and tropical fruit research institute in ahwaz. the results showed that the vardy pollen had the most signif...

in order to determine traits which affected grain yield in optimal irrigation and terminal drought deficit conditions, a field experiments with 16 spring bread wheat genotypes as randomized complete block design with three replications conducted in neishabour during 2009-10 cropping seasons. results of combined analysis of variance showed, significant differences between many of traits vegetati...

tall wheat grass (agropyron elongatum), as many other grasses, benefits from wide genetic bases in iran. estimation of genetic diversity and a selection of suitable genotypes is the initial step for developing adaptable synthetic varieties in many cool season grasses. in order to investigate production, variation and genetic similarity of 25 tall wheat grass genotypes, an experiment was conduct...

orchard grass (dactylis glomerata), a pasture and forage grass, has wide genetic distribution in iran. evolution of germplasm and selection of suitable genotypes is the first step for developing adaptable synthetic varieties. in order to investigate production potential, variation and genetic similarity of iranian orchard grass genotypes, an experiment was conducted using clonally propagated ma...

powdery mildew, caused by blumeria graminis hordei, is currently the most serious foliar disease of barley in worldwide and reduced barley yield. the use of resistant cultivars is an efficient, economical and environmentally way to control of powdery mildew in barley. in this research a half diallel design was used for genetic analysis of resistance to powdery mildew (bgh) in barley. six barley...

The aim of the apricot-breeding program in the Horticultural Faculty in Lednice, that has been developed since 1981, is to obtain new adaptable cultivars, which combine most of the valuable biological traits. Standard breeding techniques, such as crossing by emasculation and hand pollination, self-pollination and open pollination, were employed. A total of 1.154 crossings were produced from mor...
