Abstract:

Improvement in plant adaptation to various stresses is essential to ensure food security for the increasing world population. Traditional breeding methods are not to be wrathful in stress tolerant in field condition. While the next generation crop breeding technology; Genomic selection, Transcriptome mapping (ESTs, SAGE, MPSS, Microarray), Genomics (whole genome sequencing, Next Generation Sequencing and Genotyping-by-Sequencing) and Allele mining approaches will be useful for identification of gene/s, transcription factors (TF), microRNA (miRNA) and Quantitative Trait Loci (QTLs) responsible for stress tolerance. Once these are identified, the next approach is to transfer them into elite cultivars. The transgenic approach is feasible to engineer traits that are controlled by one or a few major genes and QTLs not easily amenable through transformation. For this purpose, we can use high throughput technology; marker assisted selection (MAS), marker assisted back crossing (MABC) and gene pyramiding to elucidate thousands of genes or even entire genomes. Next generation plant breeders need to utilize this next generation technologies and techniques to develop stress tolerant crops. Abbreviations: Marker Assisted Selection-MAS, Marker Assisted Back Crossing-MABC, Expressed Sequence Tags-ESTs, Serial Analysis of Gene Expression-SAGE, Quantitative Trait Loci-QTLs, Massively Parallel Signature Sequencing-MPSS, Whole Genome Sequencing-WGS, Next Generation Sequencing-NGS, Genotyping-by-Sequencing-GBS.
