The identification and introgression of major-effect QTLs for grain yield under drought are some of the best and well-proven approaches for improving the drought tolerance of rice varieties.
The identification and introgression of major-effect QTLs are one of the best and proven approaches to improving the drought tolerance of rice varieties.
An alternative to chemical hydrogenation is genetic modification of seed oil through identification and introgression of mutant alleles.
This accuracy is important for the identification and functional analysis of genes, for the identification of target genes for marker-assisted gene introgression programs, and for the prediction of the performance of crosses.
The identification and use of the iap S. bicolor accession has enabled the successful introgression of genes from undomesticated Sorghum species into cultivated sorghum, and is the first step towards accessing these unique unexploited genes for both biotic and abiotic stresses and agronomic traits.
One approach to shorten the time needed for introgression is to combine both QTL identification and introgression, into a single step.
Combining QTL identification and introgression corresponds to a continuous backcrossing scheme, where the information of the backcross generations is used to identify and map the QTL.
The number of SNPs available will thus rapidly increase, allowing the identification of new introgressions and regions of the genome under selection.
A range of genetic markers have been used to assess introgressive hybridization in cutthroat trout populations, and recently SNPs useful for species identification and detecting introgression between rainbow trout and cutthroat trout have been developed [ 28, 40, 41].
Based on these transferable markers, the molecular identification systems is able to be established for accessing the hybridization and introgression among species of the genus Phalaenopsis in future work.
