چکیده در بخش اول این پروژه دو روش میکرواستخخرا به نامهای میکرواسخخرا امولسیونی با کمک اموا فراصتتتو 1 و میکرواستتتخخرا مای – مای با کمک هوا 2 ، به عنوان دو روش میکرواستتتخخرا بدون حلال پخشکننده 3 ، برای اسخخرا برخی هیتدروکربتنهای آروماتیتک حلقوی 4 از نمونتههای آبتی بهکار گرفخه و پارامخرهای موثری همچون نوع حلال اسختتتتخرا کننده، حجم حلال اسخخرا کننده، میزان نمک، زمان تابش اموا فراصتو ، تددا...
Rice stripe virus (RSV) causes one of the most serious viral diseases of rice (Oryza sativa L.), but the molecular basis of RSV resistance has remained elusive. Here we show that the resistant allele of rice STV11 (STV11-R) encodes a sulfotransferase (OsSOT1) catalysing the conversion of salicylic acid (SA) into sulphonated SA (SSA), whereas the gene product encoded by the susceptible allele ST...
In this study, one rice population of recombinant inbred lines (RILs) was used to determine the genetic characteristics of seed reserve utilization during the early (day 6), middle (day 10) and late (day 14) germination stages. The seedling dry weight (SDW) and weight of the mobilized seed reserve (WMSR) were increased, while the seed reserve utilization efficiency (SRUE) decreased, during the ...
a 7×7 complete diallel cross experiment was performed to study the genetic relationships of grain yield and some agronomic traits in rice. analysis of variance showed significant differences among genotypes for all traits. results of correlation analysis showed that rice grain yield was positively and significantly correlated with by (rp = 0.81, rg =0.55), hi (rp =0.35, rg =0.79), np (rp = 0.80...
Rice is the staple food of half of the world's population and one of the most important crops in Central and West Asia. To assess variation in some important agronomic traits and grouping of rice genotypes, this study was performed and 49 genotypes from Azerbaijan, Kazakhstan, Afghanistan, Turkey, Kyrgyzstan, Iraq, and Uzbekistan along with 7 genotypes from Iran were evaluated using randomized ...
despite the importance of forage quality to animal performance, the quality of barley as a feed and forage crop has not been taken into consideration as a selection criterion in its breeding programs. in order to map the genomic regions affecting barley forage quality, two experiments were conducted while employing 72 doubled haploid lines and their two parents (‘steptoe’ and ‘morex’), at the r...
The identification of genomic loci involved in control of quantitative traits receives growing attention in plant molecular breeding. The present study was carried out to evaluate the genetic variability among 48 rice genotypes and determine the genomic regions associated with ten grain related important traits. A total number of 63 alleles were detected by 18 selected SSR markers from differen...
Beef cattle breeding programs focus on improving important economic traits, including growth rates, and meat quantity and quality. Molecular marker-assisted selection based on genetic variation represents a potential method for breeding genetically improved livestock with better economic traits. Smoothened (SMO) protein is a signal transducer that contributes to the regulation of both osteogene...
to investigate variation and detect of genomic regions controlling quality and quantity of malt extract in barely, a study was conducted using a set of 72 double haploid barley lines as well as their parents (stepto & morex) at experimental stations of university of mahabad and agricultural research center of mian'doab in rcbd with two replications during cropping season (2011-12). differe...
Salinity is one of the most extensive environmental stresses and is a limiting factor for the growth and development of crops, such as rice. Then, an experiment based upon completely randomized design with four low levels (0, 7.5, 15, 22.5) and four high of salinity (75, 150, 225 and 300 mM) with control as the first factor and nine cultivars of rice (dollars, Hasan Saraii, Mousa Tarom, Kamfiru...
