BREEDING OBJECTIVES
Improve Yield & Yield Stability.
Wider adaptability across geographies
Improve tolerance for Biotic stresses like sucking pest
complex, fungal, bacterial, viral diseases, Parawilt, bollworm
complex, fall armyworm, etc
Improve tolerance for Abiotic stress like drought, salinity,
lodging, photo insensitivity, etc
Increase harvest index.
Develop Genotypes for HDPS and Mechanization suitability.
Developing promising parental lines for ease in seed
production & high producible parents.
To enhance the breeding efficiency and trait introgression
by using biotechnological tools & techniques.
BREEDING FOR YIELD IMPROVEMENT
Existence of genetic diversity is an essential requirement for successful hybridization programme & choice of suitable parent through careful & critical evaluation is of paramount importance for successful hybrid development
Application of biotechnological approaches provides alternative avenues for improvement through direct manipulation of genes and can produce improvements which are not possible through classical breeding programmes.
New DNA technology can be used as a tool to facilitate the breeding process through marker-assisted selection
DNA markers are especially useful for targeting specific traits or genes of interest, monitoring alien genome introgression, providing a genetic basis for selecting particular regions of a genome that are targeted for introgression, thereby increasing the probability of choosing a desirable trait, and for reducing the size of breeding populations by evaluating the materials at early stages
FACTORS AFFECTING THE PRODUCTIVITY
Abiotic Factors - Change in climate, improper distribution of rainfall, increased heat & drought stress & poor soil conditions
Biotic Factors - Changing pest scenario & evolution of new strains of disease incidences
People says about agro
I now say that the world has the technology—either available or well advanced in the research pipeline—to feed on a sustainable basis a population of 10 billion people. The more pertinent question today is whether farmers and ranchers will be permitted to use this new technology.
Though I do not believe that a plant will spring up where no seed has been, I have great faith in a seed. Convince me that you have a seed there, and I am prepared to expect wonders.
