In order to choose an efficient breeding procedure, it is necessary to have knowledge of the genetic system controlling agronomically important traits. Common bean is one of the major legumes containing large amount of proteins and other valuable nutrients. The aim of this study was to determine genetic parameters for yield and yield components, using six generations (P1, P2, F1, F2, BC1, and B...

introduction: previous studies have shown that sesame oil affects memory and learning. in the present work, effect of a diet containing 10% sesame oil used during pregnancy was evaluated on short-term passive avoidance learning of offspring rats by shuttle box. methods: female wistar rats were divided into 2 groups (n = 9 each group). control group consumed regular diet during pregnancy and the...

Conspicuous asymmetries in forms that are polymorphic within a species can be genetically or environmentally determined. Here, we present a genetic analysis of the inheritance of dimorphic enantiostyly, a sexual polymorphism in which all  owers on a plant have styles that are consistently de ected either to the left or the right side of the  oral axis. Using Heteranthera multi ora (Ponteder...

Crosses between different genera of plants are rare and a satisfactory cytological study of such hybrids has never been made. A comparison of chromosome behavior in genus and species crosses is of interest in connection with a comparison of genetic and taxonomic relationships. A cytological analysis should also show the reason why crosses of genera are almost completely or quite sterile and whe...

The study of speciation is key to understanding the origins of biodiversity. Model organisms, with a host of genetic and molecular tools, are crucial to dissecting the genetics of speciation. Crosses between the recently-discovered Caenorhabditis sp. 9 and the well-known C. briggsae produce fertile F1 hybrid females, opening the door to genetic studies of speciation for the first time within th...

For the evolution of new pearl millet hybrids with diverse cytoplasmic background suitable for specific areas and condition, there is a need for diversified CMS sources among locally adaptable lines and identification of locally adaptable restorers. The present study was undertaken to screen the male sterile and restorer lines among the crosses of five male sterile lines and thirty inbreds of p...

Pati K., A. Das Munshi and T. Kanti Behera (2015): Inheritance of gynoecism in cucumber (Cucumis sativus L.) using genotype gbs-1 as gynoecious parentGenetika, Vol 47, No. 1, 349-356. The inheritance pattern of gynoecious sex expression in cucumber was studied by utilizing a gynoecious line (GBS-1) and two monoecious lines (Pusa Uday and Punjab Naveen). Crosses were made between gynoecious line...

The H-2Dd transgenic strain D8 on C57BL background was more resistant to subcutaneous challenge of RBL-5 lymphoma cells than B6 controls. The direct role of the H-2Dd antigen was investigated by the use of (D8 x B6)F1 crosses and (D8 B6) x B6 backcrosses. The latter showed cosegregation with regard to Dd antigen expression and lymphoma resistance, both of which were inherited in a pattern consi...

Patterns of reproductive isolation between species may provide insight into the mechanisms and evolution of barriers to interspecific gene exchange. We used data from published interspecific hybridization experiments from 14 genera of angiosperms in order to test for the presence of asymmetrical barriers to gene exchange. Reproductive isolation was examined at three life-history stages: the abi...
