Interspecific hybridization to introduce useful genetic variability for pigeonpea improvement

Identification of Drought Tolerant Lines from Interspecific Hybridization in Two Different Genetic Backgrounds of Barley under Different Irrigation Regimes

Domestication and artificial selection have reduced the level of genetic variation in barley. Inter-specific hybridization is one of the most valuable ways to restore at least part of the lost variation. This study aimed to investigate genetic diversity and screening barley lines which possessed the desired traits, as well as drought tolerance, within two F3 populations derived by crossing a cu...

Selecting parental materials for hybridization by measuring genetic diversity

Abundant genetic variability in Drosophila simulans for hybrid female lethality in interspecific crosses to Drosophila melanogaster.

Intrinsic postzygotic reproductive isolation is thought to result from the substitution of multiple harmless or beneficial genetic differences between species that are incidentally deleterious when combined in species hybrids, causing hybrid sterility or inviability. Genetic variability for hybrid sterility or inviability phenotypes is, however, rarely assessed in natural populations. Here, we ...

Genetic analysis of reaction time variability: room for improvement?

BACKGROUND Increased reaction time variability (RTV) on cognitive tasks requiring a speeded response is characteristic of several psychiatric disorders. In attention deficit hyperactivity disorder (ADHD), the association with RTV is strong phenotypically and genetically, yet high RTV is not a stable impairment but shows ADHD-sensitive improvement under certain conditions, such as those with rew...
