      THE concept of heterosis is widely used in plant and animal breeding. In many species, the controlled crossing of selected parental components, mainly inbred lines, is employed to maximize heterosis and thus agronomic performance of the resulting F 1 hybrids. However, the understanding of this biological phenomenon is limited and the genetic basis of heterosis has yet to be elucidated. The heterosis adjustments utilized by multi-breed genetic evaluation systems are another example of estimates for individual (due to a calf) and maternal (due to a crossbred dam) heterosis. These heterosis adjustments are presented in Table 5 below and illustrate the differences in expected heterosis for various breed-group Size: 59KB.

    Some aspects of work carried out on heterosis and its practical exploitation in both self- and cross-pollinated crops since are surveyed. Methods of breeding are examined with reference to the characters of parents and F1 crosses in self-pollinated plants, the relation between the characters of inbred lines and those of their F1 crosses in maize, a comparison of ways in which heterosis can Cited by: quantitative genetics and breeding methods Download quantitative genetics and breeding methods or read online books in PDF, EPUB, Tuebl, and Mobi Format.

    For a number of crops, agricultural yields have been boosted by the phenomenon of heterosis or hybrid vigor, where a hybrid outperforms either parent. Understanding the various mechanisms by which heterosis arises may facilitate the breeding of hybrids with increased vigor for further crop varieties. This issue will provide snap shots of the state of the art for linking heterosis and abiotic stress tolerance and inspire future breeding for adaptation to edaphic and climate induced stresses in sorghum and other crops.

Taschenbuch. Condition: Neu. Neuware - This is a reference book which describes importance, use and basic information relevant to application of heterosis breeding in tomato for yield and quality contributing traits.

Tomato is a tropical day neutral plant. It is self-pollinated crop but a certain extent of cross pollination may take place. 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. This includes the molecular basis of heterosis (e.g., Rosas et al., ), epigenetic phenomena (e.g., Shindo et al., ; Vaughn et al., ), or the limits of breeding due Heterosis breeding book incompatibility.

The latter phenomenon occurs frequently enough to pose a practical problem, but its potential molecular causes are only beginning to be understood. 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. Research on heterosis, male sterility systems, outcrossing mechanisms, disease/insect management, and grain quality considerations in hybrid rice are reviewed.

When trying to solicit authors for this book it became apparent that the causal factors for heterosis at the physiological and biochemical level are today almost as obscure as they were 30 years ago. Though biometrical-genetical analyses point to dispersion of complementary genes - not.

Cross pollinated species and species reproducing asexually are highly heterozygous.

When these species are subjected to selfing or inbreeding they show severe reduction in vigour and fertility. This phenomenon is known as inbreeding depression.
