Drought stress is the most important environmental stress that affects many morphological, physiological and, especially, yield traits of arable crops. In this research, a cross between the cultivar Gaspard (dehydrated susceptible parent) and DN11 line (drought resistant parent) was performed. F1, F2, F3, BC1 and BC2 generations along with parents, were planted and compared in a randomized...
There is increasing evidence that heritable variation in gene expression underlies genetic variation in susceptibility to disease. Therefore, a comprehensive understanding of the similarity between relatives for transcript variation is warranted--in particular, dissection of phenotypic variation into additive and non-additive genetic factors and shared environmental effects. We conducted a gene...
Mice carrying dominant mutations at the agouti locus exhibit ectopic expression of agouti gene transcripts, obesity, and type II diabetes through unknown mechanisms. To gain insight into the role of agouti protein in modulating adiposity, we investigated regulation of a key lipogenic gene, fatty acid synthase (FAS) by agouti alone and in combination with insulin. Both agouti and insulin increas...
The aim of this research was to estimate the influence of environmental factors, such as air temperature and milk production, on reproduction traits of primiparous Polish Holstein-Friesian cows. The following reproduction traits were considered: interval from calving to first insemination, interval from first to last insemination, interval from calving to conception, number of inseminations per...
In order to study gene action in rice for traits related to quality (gelatinization temperature, gel consistency and amylose content), four varieties of rice (Sang-e-Tarrom, Gerdeh, IRRI2 and IR229) were investigated. Ten different generations including P1, P2, F1, RF1, BC1, RBC1, BC2, RBC2, F2 and RF2 were evaluated using generation mean analysis. In generation mean analysis, one of non-alleli...
combining ability, gene action, heritability and other genetic parameters in bread wheat under drought stress condition were evaluated using half diallel design. nine wheat cultivars and 36 derived f1 assessed in a randomized complete block design with three replications in shahid bahonar university of kerman research field in 2013. evaluated genotypes showed high diversity for all traits. gene...
Five tomato cultivars were studied for inheritance of bacterial wilt resistance. Lines AVTO1429, AVTO1424, and AVTO1314 have the resistance gene, Roma VF lacks Valoria Select is claimed to but has not been evaluated. The study, which was carried out in a split plot design, involved six generations backcrosses that conducted greenhouse field. Artificial inoculation Ralstonia solanacearum greenho...
Studying the genetic structure of crops, including wheat, has always been one of the research priorities to increase the efficiency of breeding methods. In order to genetic analysis of some agronomic traits of bread wheat using generation mean analysis (GMA), all produced generations along with relevant parents of the two populations (Marvdasht × Rasoul and Marvdasht × Shahpasand) were evaluate...
