“…This was confirmed with cloned genes and amplicons in wheat and rye (Yahiaoui et al 2004;Yan et al 2006;He et al 2007He et al , 2008Varshney et al 2007;Krattinger et al 2009;Su et al 2011;Ma et al 2012). SNPs and InDels among different alleles at one locus resulted in phenotypic variations in wheat (Yahiaoui et al 2004;Yan et al 2006;He et al 2007He et al , 2008Fu et al 2009;Gupta et al 2009;Krattinger et al 2009;Su et al 2011;Ma et al 2012). FMs can be developed based on the SNPs and InDels among different alleles at one locus, and used for marker-assisted selection.…”

Functional markers (FM) are developed from sequence polymorphisms present in allelic variants of a functional gene at a locus. FMs accurately discriminate alleles of a targeted gene, and are ideal molecular markers for marker-assisted selection in wheat breeding. In this paper, we summarize FMs developed and used in common wheat. To date, more than 30 wheat loci associated with processing quality, agronomic traits, and disease resistance, have been cloned, and 97 FMs were developed to identify 93 alleles based on the sequences of those genes. A general approach is described for isolation of wheat genes and development of FMs based on in silico cloning and comparative genomics. The divergence of DNA sequences of different alleles that affect gene function is summarized. In addition, 14 molecular markers specific for alien genes introduced from common wheat relatives were also described. This paper provides updated information on all FMs and gene-specific STS markers developed so far in wheat and should facilitate their application in wheat breeding programs.

“…Recurrent selection involves alternating generations of selection and interbreeding to identify favorable genetic recombinations. MARS is a novel approach in which individuals for intercrossing are selected using a selection index-constructed, based on QTL-associated molecular markers [13,105,[124][125][126][127]. The gain from selection using such an index is expected to be higher than phenotypic selection used in conventional recurrent selection methods [128].…”

Impact of Genomic Technologies on Chickpea Breeding Strategies

Abstract:The major abiotic and biotic stresses that adversely affect yield of chickpea (Cicer arietinum L.) include drought, heat, fusarium wilt, ascochyta blight and pod borer. Excellent progress has been made in developing short-duration varieties with high resistance to fusarium wilt. The early maturity helps in escaping terminal drought and heat stresses and the adaptation of chickpea to short-season environments. Ascochyta blight continues to be a major challenge to chickpea productivity in areas where chickpea is exposed to cool and wet conditions. Limited variability for pod borer resistance has been a major bottleneck in the development of pod borer resistant cultivars. The use of genomics technologies in chickpea breeding programs has been limited, since available genomic resources were not adequate and limited polymorphism was observed in the cultivated chickpea for the available molecular markers. Remarkable progress has been made in the development of genetic and genomic resources in recent years and integration of genomic technologies in chickpea breeding has now started. Marker-assisted breeding is currently being used for improving drought tolerance and combining resistance to diseases. The integration of genomic technologies is expected to improve the precision and efficiency of chickpea breeding in the development of improved cultivars with enhanced resistance to abiotic and biotic stresses, better adaptation to existing and evolving agro-ecologies and traits preferred by farmers, industries and consumers.

“…In contrast to cereals (Koebner and Summers. 2007;Gupta et al 2010) and corn (Ragot and Lee 2007), there are very few reports of MAS in legumes (Ragagnin et al 2009;Torres et al 2010). Several factors that limit the application of MAS in legume breeding include lack of marker studies, the need to validate the effect of MAS in Varshney et al (2014) reported successful introgression of Fusarium wilt and AB resistance into an elite cultivar of chickpea through the use of marker-assisted backcrossing.…”

Chickpea (Cicer arietinum L.) is the third most economically important food legume in the world. Its yield potential is often limited by various biotic stresses, including fungal and viral diseases, insects, nematodes and parasitic weeds. Incorporating genetic resistance into cultivars is the most effective and economical way of controlling biotic stresses and this is a major objective in many breeding programs. Extensive searches for resistances have been conducted by screening commercial varieties, landraces and closely related species. Resistances to disease such as Ascochyta blight and Fusarium wilt have been identified and molecular tools are being used to increase the efficiency of gene transfer from wild species into chickpea elite genotypes. Quantitative trait loci for resistance genes have been located on linkage maps and molecular markers associated with these loci can potentially be used for efficient pyramiding of the traits. Significant chickpea genomic resources have been developed in order to investigate resistance genes. Such resources include an integrated genetic map, expressed sequence tag libraries, bacterial artificial chromosome libraries, microarrays and draft genome sequences. Although these resources have yet to be used to improve chickpea cultivars in the field, this is likely to change in the near future. These genomic resources, as well as high-resolution phenotyping tools and cutting-edge technologies such as next-generation sequencing, promise to increase efficiency as work to identify valuable candidate genes continues.
