“…Genotypes under Penang and Negeri Sembilan could be used as parents in hybridizations to obtain maximum heterosis. Several authors previously described similar results [44][45][46]. Yan et al [47] conducted AFLF marker based genetic diversity analysis among P. oleracea accessions sampled worldwide regarding alinolenic fatty acid (ALA) composition analysis.…”

“…Thus to obtain greater heterosis, in the kenaf breeding program genotypes from different clusters (Fig. 4) with high genetic variability proven by the RAPD markers could be used for effective hybridization program, which has been proposed by many researchers (Punitha and Ganesamurthy, 2010;Latif et al, 2011;Rafii et al, 2012).…”

Assessment of genetic variation in different kenaf (Hibiscus cannabinus) genotypes using morpho-agronomic traits and RAPD markers. AbstractTwenty five kenaf (Hibiscus canabinus L.) genotypes originated in different parts of the world were studied in Malaysian tropical environment to assess genetic variation using morpho-agronomic traits and random amplified polymorphic DNA (RAPD) markers. A total of 13 morpho-agronomic traits was selected for study and found that the genotypes varied significantly (p<0.01) in these traits. The major production traits such as stick weight (SW) and fiber weights (FW) were found highly correlated with other traits. Agglomerative hierarchical cluster analysis and principal component analysis (PCA) of the morpho-agronomic traits yielded four major cluster groups of the studied genotypes. The low fiber and stick yield producing early maturing genotypes were in cluster I, middle fiber weight, plant height and matured genotypes were in cluster II, and III and high fiber and stick weight producing late flowering genotypes were in cluster IV PCA of the phenotypic data using covariance matrix revealed that first three components accounted for 97.20% of total variation of the genotypes. The assessment of genetic diversity using RAPD marker revealed high genetic polymorphisms of the makers (7.2) with Jaccard's similarity coefficient of variation from 0.000 to 0.952. These findings of phenotypic and genetic variations in morphoagronomic traits and polymorphism level at DNA expressed the usefulness of these genotypes as parent materials for future improvement in kenaf breeding programs.

“…Various markers such as SSRs, RFLP and ISSR have been used to detect QTLs for blast resistance in different population and environments [49]. The 23 blast resistance loci within the QTL regions found are Pi30(t), Pi7(t), Pi34, [50].…”

“…Marker-assisted selection is a promising and efficient way to select the desirable characters indirectly in a breeding program by using different markers such as SSR, ISSR, RFLP, RAPD [49]. The selection of genes of interest depends upon the location of the marker and distance lying within gene and marker.…”

Rice blast caused by Magnaporthe oryzae is one of the most devastating diseases of rice around the world and crop losses due to blast are considerably high. Many blast resistant rice varieties have been developed by classical plant breeding and adopted by farmers in various rice-growing countries. However, the variability in the pathogenicity of the blast fungus according to environment made blast disease a major concern for farmers, which remains a threat to the rice industry. With the utilization of molecular techniques, plant breeders have improved rice production systems and minimized yield losses. In this article, we have summarized the current advanced molecular techniques used for controlling blast disease. With the advent of new technologies like marker-assisted selection, molecular mapping, map-based cloning, marker-assisted backcrossing and allele mining, breeders have identified more than 100 Pi loci and 350 QTL in rice genome responsible for blast disease. These Pi genes and QTLs can be introgressed into a blast-susceptible cultivar through marker-assisted backcross breeding. These molecular techniques provide timesaving, environment friendly and labour-cost-saving ways to control blast disease. The knowledge of host-plant interactions in the frame of blast disease will lead to develop resistant varieties in the future.
