EVOLUTIONARY CONSEQUENCES OF HYBRID STERILITY AND VIGOR IN TOADS [PDF]

open access: bronzeEvolution, 1960
Hybridization between the Gulf Coast toad, Bufo valliceps Wiegmnann, and Fowler's toad, Bufo fowleri Hinckley, is unproductive (Volpe, 1956). F1 hybrids derived from the cross, valliceps 9 X fowleri C, cytolyse in the gastrula stage of embryonic development.

Hybrid vigor and its utilization in Renge

open access: bronzeJapanese Journal of Breeding, 1961
Although Renge (Astragalus sinicus L. ) is a very important fcrage crop cultivated during winter season in Japan, studies have been rarely made on its breeding. In view of this status, the possibility of the utilization of hybrid vigor was investigated in this study.

Agronomic strategies to enhance the early vigor and yield of maize part II: the role of seed applied biostimulant, hybrid, and starter fertilization on crop performance

open access: yesFrontiers in Plant Science, 2023
Maize cropping systems need to be re-designed, within a sustainable intensification context, by focusing on the application of high-use efficiency crop practices, such as those that are able to enhance an early plant vigor in the first critical growth ...

Altered Mobility and Accumulation of Inefficient Workers in Juvenile Hybrid Termite Colonies

open access: yesFrontiers in Ecology and Evolution, 2020
Hybridization of two different species is an important mechanism to have gene flows between species. Recently, mating of two economically important invasive species of subterranean termites (Coptotermes formosanus and Coptotermes gestroi) have been ...
