Hybrid vigor and conceptual structure

Behavioral and Brain Sciences, 2010
AbstractMachery rightly points out a diverse set of phenomena associated with concepts that create challenges for many traditional views of their nature. It may be premature, however, to give up such views completely. Here I defend the possibility of hybrid models of concept structure.

Hybrid Vigor

2018
Abstract Heterosis or hybrid vigor is a phenomenon in which a hybrid progeny exhibits superior performance compared to their parental inbred lines. F1 hybrid seed production system is used for many crops and vegetables because of the high yield due to hybrid vigor. It has been over 100 years since the discovery of the hybrid vigor phenomenon; however,

Vigor in an interspecific hybrid of sansevieria

Economic Botany, 1960
F1 hybrids of S. trifasciata x S. deserti were distinctly superior to either parent species in terms of total green yield, percent fiber leaves, fiber leaf yield and fiber yield in tests conducted on Everglades peat and Immokalee fine sand in south Florida.

The genetics of hemoglobin in hybrids—I. A molecular basis for hybrid vigor

Comparative Biochemistry and Physiology, 1963
Abstract 1. 1. Hemoglobins from various bird and fish hybrids have been studied by starch electrophoresis and by oxygen equilibrium analysis. In most crosses there are no new proteins—i.e. the electriphoretic patterns for hybrids and for mixtures of the parental hemoglobins are identical. 2. 2.

Hybrid Vigor in a Tomato Cross

Botanical Gazette, 1952
1. Growth and development of two inbred lines of tomato and their hybrid were followed with respect to increase in weight, increase in height, differences of branching pattern, total phosphorus content, total nitrogen content, total starch content, catalase activity of the stem tips, and total proteolytic activity of germinating seeds and seedlings. 2.

Genetic Experiments on Hybrid Vigor in Maize

The American Naturalist, 1935
In the first section a biometrical study of the genetic nature of hybrid vigor in maize is reported. From two vigorous F1 hybrids, data on F2 yields (individual ear weights) show practically no skewness. If hybrid vigor is due to dominant size genes, some reason for the absence of F2 skewness is necessary.
