Title :	Isozyme Variations in Fine and Aromatic Rice Genotypes
Material Type:	printed text
Authors:	Bimb, Hari P., Author ; Sah, Ram P., Author ; Navin L. Karn, Author
Publication Date:	2004
Article on page:	59-64 p
Languages :	English (eng)
Keywords:	Fine  and  aromatic  rice,  genetic  diversity,  isozyme
Abstract:	Allozyme electrophoresis has been a reliable technique in estimating the genetic variation in crops. We surveyed isozyme variation of 24 aromatic and fine rice varieties collected from Nepal including Jetho budho landrace. Five enzyme systems were analyzed for allozyme variability that detected distinct 10 isozyme loci and 15 alleles including null alleles. The polymorphic enzyme systems, esterase revealed 8 phenotypes, 6- phosphoglutanate dehydrogenase and peroxidase each with 3 phenotypes and alcohol dehydrogenase and aspartate aminotransferase each with 2 phenotypes based on the combination of presence and absence of alleles. Dendrogram did not indicate any clear pattern of these populations into definite clusters. However 3 groups were detected at 84% of dissimilarity among 24 populations. Nepalese varieties Rato Basmati, Pahenle and Jetho Budho grouped in a separate cluster in the dendrogram.
