ADVANCEMENTS AND CHALLENGES OF MODERN BREEDING OVER CONVENTIONAL BREEDING
Abstract: Plant breeding dates back thousands of years, when people first deliberately bred plants based on visually pleasing characteristics. The domestication of wild plants aided this process, resulting in the evolution of numerous breeding strategies over time. Conventional breeding, which is distinguished by selective breeding based on superior performance, used procedures such as pure-line selections, mass selection, backcross breeding, recurrent selection, and hybridization. While effective, classical breeding procedures were time-consuming and …

Review on Assessment of Use and Efficiency of Mating Design in Plant Breeding
Abstract: AbstractPlant breeder works with many different characters, some of which will be controlled by genes whose individual effects can be easily detected. Selection with these characters can give spectacular results others however, form a bulk of the characters plant breeders work with and are governed by genes whose individual effects are so small that they are not amenable to conventional analysis of segregation ratios. The success of any breeding programme …

Reverse Breeding: A New Method for Crop Improvement
Abstract: Reverse breeding makes use of genetic modification to facilitate breeding of F1 hybrids by suppression of meiotic recombination which starts with an elite heterozygous line and aims at the generation of homozygous parental lines and later original heterozygous line isconstituted. The technique allows breeders to produce a hybrid in much shorter time than the conventional methods. The objectives of reverse breeding are to provide alternative method for providing homozygous parental …

A Bull Breeding Soundness Evaluation System with Greater Emphasis on Molecular Genetics
Abstract: Bull is known to be half of the herd. As bull contribute large number of progenies to the next generation as compared to females so determining the potential fertility of the bull is much more important than determining the fertility of any individual cow. It becomes critical to study and analyse the breeding potential of a bull before breeding season for getting best out of progeny. Breeding soundness evaluation (BSE) …

Breeding Strategies of Self Pollinated Crop with Special Emphasis on Hybrid Rice: Present and Future Perspectives
Abstract: AbstractDevelopment of hybrid cultivar in crop plants is a remarkable success of plant breeding. Hybrid breeding technology is greatly applied in cross pollinated crop and is limited in autogamous self pollinated crop due to strict genetic makeup of plant and floral biology. Development of genetic male sterility system in various crop plants has overcome the problem of tedious hand emasculation. Cytoplasm genetic male sterility has been widely applied in hybrid …
