Historical Perspective. Genetic Theories of Heterosis. Physiological and Biochemical Bases of Heterosis. Heterosis in Population Crosses. Hybrid Predictions. Genetics and Enhancement of Heterosis Using Molecular by:   Heterosis is a phenomenon not well understood but has been exploited extensively in breeding and commercially.

Hybrid cultivars are used for commercial production in crops in which heterosis expression is important. Hybrid vigor or heterosis is defined as a superior performance of hybrids, for many traits, relative to their parental inbred lines (see Chapter 8 of this book).

Hybrids have been widely used in crop and tree breeding since ancient times, although the molecular mechanisms underlying heterosis have yet. J.F. Crow, in Encyclopedia of Genetics, An understanding of heterosis in genetic terms had to await the rediscovery of Mendel's laws in It was immediately apparent that hybrids are more heterozygous than their parents.

A decrease in the number of heterozygotes implied an increase in the number of homozygotes. Heterosis, also called hybrid vigour, the increase in such characteristics as size, growth rate, fertility, and yield of a hybrid organism over those of its parents. Plant and animal breeders exploit heterosis by mating two different pure-bred lines that have certain desirable traits.

The first-generation offspring generally show, in greater measure, the desired characteristics of both parents.

Heterosis And Hybrid Seed Production In Agronomic Crops Epub Format - Stan and Jan Berenstain Public Library Heterosis And Hybrid Seed Production In Agronomic Heterosis book Discusses How Heterosis Or Hybrid Vigor Has Played A Major Role In.

Preface. The chapters for this book are based on 40 plenary presentations by invited speakers and related question-and-answer sessions from the international symposium, The Genetics and Exploitation of Heterosis in Symposium was organized and hosted by the International Maize and Wheat Improvement Center (Centro Internacional de Mejoramiento de Maíz y Trigo, CIMMYT) in Mexico City.

Heterosis in animals: (i) Mule is a hybrid from a cross between Jack (Equus hemicus) and Mare (Earns equus) which has been known since ancient times for its well-known qualities of strength and stubbornness.

(ii) Cross between red Sindhi breed of Indian Cattle and Jersey breed of America contams 30% more butter fat in milk. Fixation of heterosis. Hybrid vigour has been exploited in both self as well as cross pollinated species.

The expression Heterosis book heterosis is restricted to the hybrid individual (F1 generation) and it dissipates in the advanced generations or in the progenies derived from it due to segregation and recombination which disturb the original heterotic combination of genes.

Studies have shown that the exploitation of heterosis has the potential to overcome the yield plateau in wheat. Heterosis is the increase or decrease in vigour of hybrids when com-pared with that of its parents (Sharif et al.

Heterosis It is defined as the superiority of F 1 hybrid over both the parents in terms of yield or some other characters. The term heterosis was first used by Shull in Types of heterosis 1. Average heterosis It is the heterosis where F 1 is superior to mid parent value.

Heterosis in Plant Breeding. In book: Plant Breeding Reviews, Vol pp - Heterosis can also be captured and fixed through the process of polyploidization which is common in Author: Charles Stuber.

Heterosis refers to the phenomenon that progeny of diverse varieties of a species or crosses between species exhibit greater biomass, speed of development, and fertility than both parents. Various models have been posited to explain heterosis, including dominance, overdominance, and pseudo-overdominance.

Book Description. Heterosis and Hybrid Seed Production in Agronomic Crops discusses how heterosis or “hybrid vigor” has played a major role in improving crop productivity and quality in order to feed the ever-increasing human population, particularly in developing countries.

Some aspects of work carried out on heterosis and its practical exploitation in both self- and cross-pollinated crops since are surveyed.
