the present research was conducted under laboratory and field condition to determine seed priming effects on maize inbred line's germination, emergence, and grain yield. seeds of two maize inbred lines include of mo17 (as paternal line) and b73 (as maternal line with cytoplasmic sterility) in the laboratory conditions were subjected to hydropriming for 12, 24, 36 and 48 h, or osmoticprimin...
To investigate the effect of different planting row ratios of parental lines and agronomic methods on synchronizing of flowering and seed production of SCK703 hybrid maize, a field experiment was carried out as a strip plot arranegemnts in randomized complete block design with three replications in southern Kerman agricukltural and natural rseraech and education center, Jiroft, Iran, in 2015 gr...
keeping constant all agronomic factors except temperature is a way to follow heat shock proteins (hsps) expression. three different sunflower hybrids derived from the cross between an inbred line, cms ha 89, and three different restorer inbred lines, with resistance, susceptible, and normal reactions to drought, were produced. in order to investigate the impact of temperature on protein accumul...
An essential factor in the success of multiple ovulation and embryo transfer programmes (MOET) any species is selection recipient females. In rabbit there a notable lack studies on effects genotype postnatal growth. The aim this study was to evaluate maternal genotypes litter size components within MOET programme applied commercial paternal line that appears have exhausted its after 37 generati...
Androphilia refers to sexual attraction to adult males, whereas gynephilia refers to sexual attraction to adult females. Male androphilia is an evolutionary paradox. Its development is at least partially influenced by genetic factors, yet male androphiles exhibit lower reproductive output, thus raising the question of how genetic factors underlying its development persist. The sexual antagonism...
The claim that a Mytilus galloprovincialis male failed to transmit mtDNA to its sons in controlled crosses is shown to be false. At present there is no evidence for mussel males lacking a paternal mtDNA. This makes unlikely the hypothesis that maternal genomes may become paternally transmitted by invading the germ line of males that lack a paternal genome.
Germ-line mutation induction at mouse minisatellite loci by acute irradiation with x-rays was studied at premeiotic and postmeiotic stages of spermatogenesis. An elevated paternal mutation rate was found after irradiation of premeiotic spermatogonia and stem cells, whereas the frequency of minisatellite mutation after postmeiotic irradiation of spermatids was similar to that in control litters....
in order to investigate the growth curve of broiler chickens at line level, respectively 154 and 144 birds from two paternal lines a and b of a commercial broiler line were used. line a were selected several generations for low feed conversion rate and line b were selected several generation for high body weight. body weight was measured at 1, 4, 7, 10, 14, 17, 21, 28, 35, 42, 49 and 54 days of...
