Study of Genetics Essay -- Biology, Genomics Era, Kenaf

1INTRODUCTIONKenaf (Hibiscus cannabinus L.) is a type of graphic symbol crop (Dempsey, 1975) and is commercially cultivated in more than 20 countries, particularly in India, China, Thailand and Vietnam (Fao, 2008). cosmos production of kenaf and allied fibers account as 3,251,125 scores in 2009 (Fao, 2011). Kenaf has a wide range of applications in make biocopmosite board, textile, industrial filters, and high-quality paper. Malaysia is one of the main exporters of timber and timber based products in the world. renewable resource for biocomposite and timber based products in Malaysia is one of the essentials in cultivation sector. Kenaf has been considered as a potential renewable source for biocomposite making industry in Malaysia. Furthermore, kenaf has been considered as a valuable ease for tobacco plantation in Malaysia. Kenaf production is increased from 1,163 tons in 2005 to 4,185 tons in 2007 as reported by economic Planning Unit, Prime Ministers Department, Malaysia (2 008). Lack of suitable kenaf varieties for Malaysian mode is one the challenges that hinder kenaf integration. Kenaf varieties have not been extensively evaluated in Malaysia. The number of kenaf commercialized varieties is limited in the world. Besides, real few studies have been conducted on genetic control of fiber afford and fiber quality of kenaf. Understanding of the inheritance and genetic control of the fiber yield and quality will help in structuring breeding outline to develop cultivars with improved fiber yield and quality. New tools and methods have been introduced to promote quantitative genetic studies, particularly in the study of complex traits. In genomics era, plant breeders benefited from new technologies and advances i... ...echnology to detect DNA break up behavior and developments in saturating DNA dyes, made possible to accurately plot and analyze melting behavior of targeted DNA (Vossen et al., 2009). High resolution melting (HRM) is a take PCR techni que which can be used for high throughput mutation scan and genotyping (Gundry, 2003). HRM curve analysis procedure can be used for SNP spying (Becsgh et al., 2010 De Koeyer et al., 2010 Lehmensiek et al., 2008 Miyamoto et al. Rouleau et al., 2009 Studer et al., 2009a Ujino-Ihara et al., 2010 Wittwer et al., 2003 Wittwer, 2009). Applicability of HRM curve analysis for genotyping of plants using SNP markers recently have been reported by many researcher (De Koeyer et al., 2010 Ganopoulos et al., 2010 Hofinger et al., 2009 Lehmensiek et al., 2008 Picard and Bosco, 2008 Studer et al., 2009b Ujino-Ihara et al., 2010).
