“…Sequence analysis has been used as a great tool in the genetic analysis of plant species under control or disease conditions (Alberts et al, 2002;Prida et al, 2012;Qin et al, 2014;Das et al, 2017). The hybrid rice breeding system has contributed greatly to the production of rice, which is one of the most important grain crops Supplementary Table S1: Primers for RT-PCR analysis…”

Rice blast and false smut are severe diseases of rice reducing not only rice yield but also affect grain quality. The most effective and economical mean of controlling diseases is to breed disease-resistant rice cultivars. Here, we used 18 hybrid rice varieties for identifying their functional rice blast resistance genes, and for estimating their sensitivities to false smut disease. This experiment was conducted in Sichuan Province, China in 2012-2014. The results showed that the Pi2 and Pik loci have strong rice blast resistance. Rice varieties i.e. CNY445, CNYHZ, and YXY2115 expressed the Pi2, while CFY188 and LY908 expressed Pikm. Varieties R18/2348, CGY2348, GY66, YLY973 and N5Y828 demonstrated strong resistance to rice false smut. No correlation in the resistance between rice blast and false smut was observed among the 18 hybrid rice varieties. These results can provide guidance for rational distribution of hybrid rice varieties.

“…Improved molecular marker technologies may enable bean breeders and geneticists to speed up cultivar development. An important intermediate step in this direction is to transfer desirable QTLs (genes) into active breeding populations using MAS-and to transfer multiple traits through gene pyramiding (Das et al 2017). Progress has been made in applying MAS toward improved resistance and it is described by Miklas et al (2006) and Tryphone et al (2013).…”

Common bean (Phaseolus vulgaris L.), one of the most important grain legume crops for direct human consumption, faces many challenges as a crop. Domesticated from wild relatives that inhabit a relatively narrow ecological niche, common bean faces a wide range of biotic and abiotic constraints within its diverse agroecological settings. Biotic stresses impacting common bean include numerous bacterial, fungal, and viral diseases and various insect and nematode pests, and abiotic stresses include drought, heat, cold, and soil nutrient deficiencies or toxicities. Breeding is often local, focusing on improvements in responses to biotic and abiotic stresses that are particular challenges in certain locations and needing to respond to conditions such as day-length regimes. This review describes the major breeding objectives for common bean, followed by a description of major genetic and genomic resources, and an overview of current and prospective marker-assisted methods in common bean breeding. Improvements over traditional breeding methods in CB can result from the use of different approaches. Several important germplasm collections have been densely genotyped, and relatively inexpensive SNP genotyping platforms enable implementation of genomic selection and related markerassisted breeding approaches. Also important are sociological insights related to demand-led breeding, which considers local value chains, from farmers to traders to retailers and consumers.

“…In addition, two more factors limiting the use of markerassisted selection in plant breeding are the equipment and consumables. These two are required to establish and maintain a molecular marker laboratory and therefore, their costs should be considered [7,121]. Development of markers also requires large initial costs and should be put into consideration.…”

Marker-assisted selection and gene pyramiding are very important breeding strategies for conferring broad spectrum and durable resistance against diseases causing yield loss in rice. One such disease causing major set backs in rice production is bacterial leaf blight (BLB) caused by the pathogen Xanthomonas oryzae pv. oryzae. Molecular markers are very essential in both markerassisted selection and pyramiding of genes, hence, many molecular marker techniques have already been developed. Presently, the most commonly used ones are DNA-based markers also known as molecular markers. The molecular markers are classified into two major categories based on the techniques used for detecting them. These are hybridization and polymerase chain reaction-based markers. Other types of markers available include the morphological (traditionally based) and biochemical (enzyme-based) markers. Host plant/varietal resistance is the most suitable means for controlling BLB disease of rice. Marker-assisted gene pyramiding has the potential to accelerate the breeding programmes and guarantee the durability of resistance conferred in the host plant. Therefore, this paper uncovers the utilization, economic importance, limitations and future prospects of marker-assisted selection and gene pyramiding for resistance to BLB disease of rice.
