to evaluate the genetic diversity in twenty barley genotypes, an experiment based on randomized complete block design with three replications was done at agriculture researches station of ardabil, iran in 2009-10. investigated traits of this study was included days to flowering, plant height, 1000 seed weight, number of infertile tiller, number of seed per spike, harvest index, days to maturity...

In the past, domesticated animals were genetically improved by identifying meritorious individuals, mating animals displaying desired traits, continued breeding of related animals to perpetuate their superior traits and crossbreeding when inbreeding depression became evident. Today, assisted reproduction and biotechnology allow breeders to design and direct the reproductive course, disseminate ...

this study was carried out to purify chitti bean cultivars. in the first year, 11 populations were collected from main chitti bean cultivating areas. based on some criteria such as higher yield, earlier maturity, more pods and tolerance to pests and diseases, single plants were selected. in the second year, seeds of each selected single plant as well as controls (talash and cos16) were managed ...

identification of selection targeted genomic regions is one of the most challenging areas of research in animal genetics, particularly in livestock. we carried out a genome-wide scan for signatures of positive selection to identify genomic regions that had been under selection in iranian khuzestani and mazandrani buffalo breeds. a total of 148 water buffalo from khuzestani (n=121) and mazandran...

considering the rich diversity of grape germplasm of iran, the severe cold winter occurred in 2007, provided a chance to evaluate responses of selected superior clones of iranian seedless grape ciltivars to cold in natural and artificial (in freezer) conditions. four one-year old branches per plant in each clone were selected and number of healthy and damaged sprouts were counted. based on cold...

this study was conducted to evaluate 13 promising triticale lines and cultivars based on yield traits, metabolizable energy and anti-nutritional compounds. the experiment was carried out using a rcb design with three replications at the seed and plant improvement institute, karaj and gonbad, during 2008-2009 cropping season. these genotypes were studied in the next year, at the animal science r...

Aims: It was aimed to investigate postoperative conformal radiotherapy planning that provides the best target volume and the least dose for critical organs in cancers of stomach. Methods: This study was conducted on the CT simulation images of thirty patients diagnosed with gastric cancer. Target volumes and the organs at risk were contoured. AP-PA reciprocal parallel field conventional plan an...
