APPLICATION OF DNA MARKERS FOR THE DETECTION OF AMYLOSE CONTENT IN SRI LANKAN RICE (ORYZA SATIVA L.) VARIETIES

Kottearachchi, N.S.; Peiris, R.K.; Rebeira, S. (Asian J Agri Biol, 2014)

Grain quality improvement of rice is considered as prioritized research area in rice breeding programs in Sri Lanka. Amylose Content (AC) is a key determinant of end quality of rice. Amylose Content is controlled by ...
Comparative Analysis of Salinity Responsive Candidate Gene Expression in Selected Sri Lankan Rice Varieties

Gimhani, D.R.; Vergara, G.; Gregorio, G.B.; Kottearachchi, N.S. (2015)

Studying of expression dynamics of salt responsive candidate genes under different genetic background of rice is important to develop resilient salt tolerant rice varieties. The present study was focused to assess ...
In silico analysis of the fragrance gene (badh2) in Asian rice (Oryza sativa L.) germplasm and validation of allele specific markers

Withana, W.V.E.; Kularathna, R.M.R.E; Kottearachchi, N.S.; Kekulandara, D.S; Weerasena3, J.; Steele, K.A. (Plant Genetic Resources: Characterization and Utilization, 2020-01-08)

Badh2 of rice is considered to be the major gene responsible for the fragrance in rice. The wild type badh2 allele encodes betaine aldehyde dehydrogenase 2 (BADH2) enzyme while the mutated version of badh2 gene encodes ...
In silico molecular and morphological analysis of rice blast resistant gene Pi-ta in Sri Lankan rice germplasm

Terensan, S; Fernando, H.N.S.; Silva, J.N.; Perera, S.A.C.N; Kottearachchi, N.S.; Weerasena, O.V.D.S (Journal of Genetic Engineering and Biotechnology, 2021)

Pi-ta is a major blast resistant gene, introgressed from indica rice varieties. In this study, diversity of the Pi-ta gene of 47 Sri Lankan rice accessions was studied by bioinformatics, and the results were validated ...
Single nucleotide polymorphisms in GBBSI and SSa genes in relation to starch physicochemical properties in selected rice (Oryza sativa L.) varieties

Alweera, D; Kottearachchi, N.S.; Gimhani, D. R.; Senarathna, K (WORLD JOURNAL OF BIOLOGY AND BIOTECHNOLOGY, 2020-05-09)

Starch quality is one of the most important agronomic traits in rice (Oryza sativa L). In this study, we identified single nucleotide polymorphisms (SNPs) in the Waxy and Alk genes of eight rice varieties and their ...
SNP‑based discovery of salinity‑tolerant QTLs in a bi‑parental population of rice (Oryza sativa)

Gimhani, D. R; Gregorio, G.B.; Kottearachchi, N.S.; Samarasinghe, W. L. G. (© Springer, 2016)

Breeding for salt tolerance is the most promising approach to enhance the productivity of saline prone areas. However, polygenic inheritance of salt tolerance in rice acts as a bottleneck in conventional breeding for ...
Utilization of SNP-based Highly Saturated Molecular Map of a RIL Population for the Detection of QTLs and Mining of Candidate Genes for Salinity Tolerance in Rice

Abhayawickrama, B.P.; Gimhani, D.R.; Kottearachchi, N.S.; Herath, V. (The Journal of Agricultural Sciences - Sri Lanka, 2020)

Purpose : Previously, QTL hotspots were identified for salt tolerance from a RIL population of At354 x Bg352, under a temperature-controlled environment at the International Rice Research Institute, Philippine. However, ...
