“…This resistance gene had been widely used and had been highly effective in different parts of Europe and China years ago (Liu et al, 2000). Though the growing number of virulent strains has been reported in some parts of China, the gene occurs in high frequency in so many commercial cultivars as it is easily transferred from resistant to susceptible cultivars (Parks et al, 2008;Gao et al, 2012).…”

A study was conducted to detect the presence of disease resistance genes to infection of wheat powdery mildew (Blumeria graminis f. sp. tritici) in selected wheat cultivars from China using molecular markers. Genomic DNA of sixty cultivars was extracted and tested for the presence of selected prominent resistance genes to the fungal disease using molecular markers linked to Pm genes. Results showed that 17 cultivars were detected with Pm2 gene, 24 cultivars were detected with Pm4b gene, two cultivars were detected with Pm6 gene while 24 wheat cultivars were detected with Pm8 gene. Multiple genes were also detected in the study. Cultivars Xinxuan2039, Lankao008 and Zhengmai366 were detected with possible multiple Pm2+Pm4b+Pm8 genes while Yumai368 was detected with possible multiple genes Pm2+Pm4b+Pm6. The results of this study provide a significant contribution to breeding for resistance to wheat powdery mildew disease since the identified cultivars detected with Pm genes will contribute to further studies on improving wheat resistance to the disease. Also, the continued resistance of cultivars with designated resistance genes demonstrates that the responsible Pm genes are still effective in overcoming powdery mildew infections.

“…Anderson (2007) reported that molecular mapping and MAS are modern tools that help in the exploitation and combining of different resistance genes into a single cultivar within a short period of time. Molecular markers are useful for discovery of new plant genotypes in segregating wheat populations (Liu et al 2000). Roelfs (1988) reported that resistance based on the generation of lines with a combination of more resistance genes is a recommended approach to offer long durable resistance.…”

Shah L., Ali A., Zhu Y., Wang S., Si H., Ma C. (2017): Wheat resistance to Fusarium head blight and possibilities of its improvement using molecular marker-assisted selection. Czech J. Genet. Plant Breed., 53: 47−54.Wheat, one of the world's major crops, is seriously affected by fungal diseases, especially in regions with high moisture and moderately warm temperatures. This paper reviews various molecular and conventional techniques that are used to identify genotypes with resistance alleles associated with Fusarium head blight (FHB) diseases. Quantitative trait loci (QTL) type II, designated as Fhb1, are frequently applied in plant breeding, and the newly recognized genes related to resistance to this fungal disease give extra insights into marker-assisted selection (MAS). Molecular markers are robust tools that may be routinely used in MAS for the mapping of resistance genes in crop breeding. FHB resistance is polygenic, and different resistance genes could be conveyed into a single genotype by MAS, which might ensure greater resistance to FHB disease. In conclusion, different researchers have used various techniques to control FHB resistance, such as MAS, gene pyramiding (through backcross), and molecular markers (association with resistance QTLs or genes).

“…Because of this, recent plant breeding programs targeted at the identification and pyramiding of several major genes against a number of pathogenic races [11,15]. into crops including powdery mildew resistance genes (Pm2+Pm4a, Pm2+Pm21, Pm4a+Pm21) into wheat line [21], bacterial blight resistance genes (xa5, xa13, and Xa21) into rice [22], rust resistance genes (Lr41, Lr42 and Lr43) into wheat [23], late blight resistance genes (Rpi-mcd1 and Rpi-ber) into potato [24] etc. Therefore, it is important to deduce that molecular markers have remarkable applications in resistance gene/QTLs identification, mapping and pyramiding into crop plants to develop durable/ broad spectrum resistance to biotic stresses.…”

Biotic stresses significantly limit global crop production. Identification and use of resistant cultivars is currently seen as the best strategy, cheapest, durable and environmentally friendly method to manage biotic stresses. However, resistance gained through single gene/quantitative trait loci (QTLs) transfer leads to resistance breakdown within a short period. Hence, current breeding programs targeted at developing durable and/ broad spectrum resistant cultivars by pyramiding multiple resistant genes/QTLs. Despite its significant contributions to crop improvement, gene pyramiding through conventional breeding suffers from being laborious, time consuming, costly and less efficient. Recently, the use of modern molecular tools like molecular markers and genetic engineering has dramatically enhanced the gene pyramiding strategy for biotic stress resistance. Molecular markers are very helpful for precise identification, mapping and introgression of multiple desirable genes/QTLs underlying trait of interest. Moreover, Genetic engineering has enabled scientists to transfer novel genes from any source into plants in a single generation to develop cultivars with the desired agronomic traits. Therefore, the current paper targeted to review the different types of biotic stress resistance in plants and the methodologies for identification, mapping and pyramiding of resistance genes/QTLs to develop durable and/or broad spectrum biotic stress resistant cultivars. So far, numerous crops with durable/broad spectrum resistance to pathogens, insect pests and herbicides have been developed by pyramiding multiple resistant genes/QTLs using marker assisted selection and genetic engineering techniques to contribute to increased crop production and productivity to maintain food security globally.
