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

1INTRODUCTION rheumatism weed (Hibiscus discountnabinus L.) is a caseful of fiber crop (Dempsey, 1975) and is commercially cultivated in more than 20 countries, particularly in India, China, Thailand and Vietnam (Fao, 2008). World production of kenaf and allied fibers describe as 3,251,125 tons in 2009 (Fao, 2011). bimli hemp has a wide consort of applications in making biocopmosite board, textile, industrial filters, and high-quality paper. Malaysia is one of the main exporters of character and timber based products in the world. Renewable resource for biocomposite and timber based products in Malaysia is one of the essentials in agriculture sector. Kenaf has been considered as a emf renewable source for biocomposite making industry in Malaysia. Furthermore, kenaf has been considered as a valuable substitute 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 Depa rtment, Malaysia (2008). Lack of suitable kenaf varieties for Malaysian climate is one the challenges that hinder kenaf integration. Kenaf varieties have not been extensively evaluated in Malaysia. The number of kenaf exploit varieties is limited in the world. Besides, very few studies have been conducted on inheritable control of fiber kick in and fiber quality of kenaf. Understanding of the hereditary pattern and genetic control of the fiber yield and quality will cooperate in structuring breeding strategy to develop cultivars with improved fiber yield and quality. New tools and methods have been introduced to facilitate 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 deoxyribonucleic acid melting behavior and developments in saturating DNA dyes, made possible to accurately plot and analyze melting behavior of targeted DNA (Vossen et al., 2009) . High resolving power melting (HRM) is a post PCR technique which can be utilize for high throughput mutation scanning and genotyping (Gundry, 2003). HRM curve analysis procedure can be used for SNP detection (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 utilize 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).
