Conventional breeding programs

Heterosis, a multigenic complex trait extrapolated as sum total of many phenotypic features, is widely utilized phenomenon in agricultural crops for about a century. It is mainly focused on establishing vigorous cultivars with the fact that its deployment in crops necessitates the perspective of genomic impressions on prior selection for metric traits. In spite of extensive investigations, the actual mysterious genetic basis of heterosis is yet to unravel. Contemporary crop breeding is aimed at enhanced crop production overcoming former achievements.

Study on androgenesis, highlights the feasibility of invitro haploid production in bhimkol using anthers at uninucleate stage of pollen. These haploids plants obtained could be used in conventional breeding programs to generate pure homozygous lines and auto-tetraploids in a single generation.

Cotton is the very important commercial and cash crop, it is a very much necessary to improve the Superior agronomic traits to withstand against biotic and abiotic stress in the field and fiber qualities to meet requirement of advance spinning technology. Cotton improvement through conventional breeding is time consuming, in this context molecular markers found that efficient tool to accelerate the plant breeding program in cotton improvement. At present variety of molecular markers are available, choice of molecular marker depends on the user.

Fruits and vegetables are often referred to as “protective foods” because they are rich in minerals and vitamins. Fruit production is severely impacted by various biotic and abiotic stresses and during the past, efforts have been made by conventional breeding programs to mitigate these problems. However, classical breeding has had little success in improving fruit plants and is constrained due to long juvenile period, genetic erosion, genetic drag and reproductive barriers that limit the transfer of favourable genes from diverse genetic resources.

Coconut has a wide range of applications from culinary to industrial areas. Loss of coconut trees due to the devastating effect of deadly diseases and the natural aging of the plants demand rejuvenation of orchards with elite seedlings. A conventional breeding program is not sufficient to meet the growing need for healthy planting materials. However, in vitro culture studies can pave the way for mass multiplication. In this study, the effect of TDZ on sliced mature embryo explants through direct organogenesis of coconut var. Chowghat Orange Dwarf (COD) was investigated.

The concept of 'biotech' or 'biotechnology' encompasses a wide range of procedures (and history) for modifying living organisms according to human purposes — going back to domestication of animals, cultivation of plants, and "improvements" to these through breeding programs that employ artificial selection and hybridization. Modern usage also includes genetic engineering as well as cell and tissue culture technologies.
