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 to 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. The book contains a wealth of useful information for practicing hybrid rice breeders, seed producers, researchers, and students of Brand: Springer-Verlag Berlin Heidelberg.

ADVERTISEMENTS: In this article we will discuss about Heterosis or Hybrid Vigour: 1. Meaning of Heterosis 2. History of Heterosis 3. Types of Heterosis 4. Causes 5. Effects. Meaning of Heterosis: When two homozygous inbreeds (a true breeding line obtained by continuous inbreeding) of genetically unlike constituents are crossed together, the resulting hybrids obtained from [ ].

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.
Concepts and breeding of heterosis in Crop Plants, the third joint plant breeding symposia, was held on Sunday, 3 November in Indianapolis at the ASA-CSSA-SSSA national meetings. The topic of heterosis grew out of discus s and s as evidenced by . heterosis. Also, linkage is not needed to achieve heterosis. If true, it should NOT be possible to obtain an inbred that performs equally as well as the best hybrid Bernardo Breeding for Quantitative Traits in Plants pp File Size: 1MB. Studies conducted at the International Rice Research Institute (IRRI) during and have shown up to 73% heterosis, 59% heterobeltiosis and 34% standard heterosis for yield in rice. The latter was estimated in comparison to commercial varieties: IR36 and IR42 (yield 4–5 t/ha in wet season trials and 7–8 t/ha in dry season trials). Generally speaking, absolute yield was lower and Cited by: Get this from a library! Heterosis and hybrid rice breeding.
