Basis for selection in 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.

Domestication and selection of Vitis vinifera L. for table and wine grapes has led to a large level of berry size diversity in current grapevine cultivars. Identifying the genetic basis for this natural variation is paramount both for breeding programs and for elucidating which genes contributed to crop evolution during domestication and selection processes

Hybrid breeding technology is one of the most feasible options to meet the future food challenges and sustainable agriculture. Large number of cross combinations are attempted and evaluated in hybrid breeding programs, but a few are selected. This is labour intensive, time consuming and costly; despite of it selection efficiency is too low. Therefore, it is important to explore alternate approaches to enhance the selection efficiency to predict hybrid performance. Pedigree data of the parental lines and molecular marker have been effectively employed to predict field performance of hybrids.
