“…Pinheiro et al . [ 13 ] developed the cultivar Cica-8 by crossing the susceptible cultivar Metica-1 to the resistant cultivar Cica-8, and they found that one microsatellite marker, RM7102, was closely linked to the resistant allele. Yang et al [ 132 ], while working on identifying and mapping the Pi41 gene, utilized resistant cultivar 93-11 and susceptible cultivar Nipponbare, as well as an F 2 population derived from a cross of these two cultivars.…”

Over the last few decades, the use of molecular markers has played an increasing role in rice breeding and genetics. Of the different types of molecular markers, microsatellites have been utilized most extensively, because they can be readily amplified by PCR and the large amount of allelic variation at each locus. Microsatellites are also known as simple sequence repeats (SSR), and they are typically composed of 1–6 nucleotide repeats. These markers are abundant, distributed throughout the genome and are highly polymorphic compared with other genetic markers, as well as being species-specific and co-dominant. For these reasons, they have become increasingly important genetic markers in rice breeding programs. The evolution of new biotypes of pests and diseases as well as the pressures of climate change pose serious challenges to rice breeders, who would like to increase rice production by introducing resistance to multiple biotic and abiotic stresses. Recent advances in rice genomics have now made it possible to identify and map a number of genes through linkage to existing DNA markers. Among the more noteworthy examples of genes that have been tightly linked to molecular markers in rice are those that confer resistance or tolerance to blast. Therefore, in combination with conventional breeding approaches, marker-assisted selection (MAS) can be used to monitor the presence or lack of these genes in breeding populations. For example, marker-assisted backcross breeding has been used to integrate important genes with significant biological effects into a number of commonly grown rice varieties. The use of cost-effective, finely mapped microsatellite markers and MAS strategies should provide opportunities for breeders to develop high-yield, blast resistance rice cultivars. The aim of this review is to summarize the current knowledge concerning the linkage of microsatellite markers to rice blast resistance genes, as well as to explore the use of MAS in rice breeding programs aimed at improving blast resistance in this species. We also discuss the various advantages, disadvantages and uses of microsatellite markers relative to other molecular marker types.

“…Significance of molecular markers in this study is that there is no other clear-cut validation procedure for quantifying disease resistance. ISSR and SSR primers are proved to be efficacious in tagging resistant genes by many workers [47][48][49]. The ISSR marker UBC857 and SSR marker mTcCIR42 was figured to be linked with VSD resistance by Chandrakant, (2014) [25] and further validated by Tulshiram, (2016) [26].…”

Cocoa (Theobroma cacao L.) is native to humid tropical region of Central America and considered as important agro forestry tree species. Vascular streak dieback (VSD), a devastating disease with distinct symptoms of dieback, is one of the major threats for cocoa cultivation. Th e confounding part of this disease is that chemicals have little effect on disease control. The most tenable and economic technique to tackle this disease is by evolving resistant materials. When this disease began to assume unmanageable magnitudes in India, Kerala Agricultural University had initiated VSD resistant breeding since 1995. Initially, 566 hybrids which expressed tolerance in the nursery for two years were field established. After fifteen years of field screening, 46 hybrids which manifested field resistance were selected for further study. Examination on self-incompatibility position exhibited that majority of them (37) were self incompatible. When yield contributing characters were accessed VSD I 31.8 was found to be superior and out rated the checks, most popular varieties available. Disease resistance was further confirmed by budding and molecular markers.VSD I 31.8 (CCRP 15) can be consider as a novel hybrid released in the world with VSD resistance and considerable yield.

“…This can be done with DNA marker-assisted selection. In many crops, DNA markers have been successfully used, of which E Matsuo et al microsatellites and SNPs (Single Nucleotide Polymorphism) are the most commonly used for the selection and mapping of genomic regions associated with genes and QTLs, as in soybean (Fuganti et al 2004, Morceli et al 2008, Dias et al 2009), rice (Pinheiro et al 2012) and maize (Teixeira et al 2013). Certainly, microsatellite markers have been used due to their high polymorphism, codominance, reproducibility and good distribution throughout the genome Grattapaglia 1998, Song et al 2004).…”
