Simultaneous Selection for Seed Yield and Agronomic Traits in Sunflower
Selection of high yielding genotypes is very important in sunflower. Thus, 24 new sunflower hybrids along with Golsa cultivar were evaluated in a simple lattice design (5×5) with two replications in the Agriculture Research Station of Gorgan, north of Iran, during 2020. The genotype by yield × trait (GYT) biplot method was used in order to study the relationships between different traits and to...
متن کاملChanges in Quantitative Traits of Tribolium under Irradiation and Selection.
ELECTION is recognized as a major force in the evolution of domesticated species. Yet when experimental populations are subjected to continuous selection for long periods, responses to selection become refractory in spite of demonstrable genetic variation. While differing in details, the general pattern has been a linear response in the early generations followed in the long term by plateaus in...
متن کاملCorrelated behavioral traits in rats of the Roman selection lines.
The current theories of animal personality are based on the observation that individual variation in behavior and physiology appears to be consistent across contexts. Rats of the Roman selection lines have been originally selected for differences in shuttle-box behavior. Besides differences in active avoidance, these animals differ more generally in coping style. Roman high avoidance (RHA) rats...

15 صفحه اولCorrelated responses in reproductive and carcass traits to selection for 70-day weight in Landrace swine.
Correlated responses in reproductive and carcass traits were studied in 181 litters and 218 pigs from a line of Landrace pigs selected six generations for increased weight at 70 d of age and a contemporaneous, randomly selected control line. The reproductive and maternal traits studied included litter sizes born, born alive, and alive at 21 d and litter weight at birth and at 21 d. Carcass trai...
