Title : Isozyme variations in fine and aromatic rice genotypes Material Type: printed text Authors: H.P Bimb ; Koirala, K.B., Author ; Sah, R.P., Author ; N.K Lal, Author ; B.P Sah, Author Pagination: 145-155 p. Languages : English (eng) Abstract: Rice is the main staple food crop in Nepal. Fine and aromatic rice varieties have
significant commercial value. Allozyine electrophoresis has been a reliable technique in
estimating the genetic variation in crops. We surveyed isozyme variation of 24 fine and ·
aromatic rice_ genotypes collected from Nepal including Jetho budho land race as a
check. Five enzyme system5-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 following 6- phosphoglutanate dehydrogenase and
peroxidase each with 3 phenotypes an_d alcohol dehydrogenase and asparate
aminotransferase each with 2 phenotypes based on the combination of presence and
absence of alleles. T}J,e results indicated diversity within and between population of test
genotypes. Dendrogram did not indicate any clear pattern of divisions 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.Link for e-copy: http://elibrary.narc.gov.np/?r=1096 Isozyme variations in fine and aromatic rice genotypes [printed text] / H.P Bimb ; Koirala, K.B., Author ; Sah, R.P., Author ; N.K Lal, Author ; B.P Sah, Author . - [s.d.] . - 145-155 p.

Title : Isozyme variations in rice varieties for midd-hills of Nepal Material Type: printed text Authors: H.P Bimb ; Koirala, K.B., Author ; Sah, R.P., Author ; N.K Lal, Author Pagination: 136-144 p. Languages : English (eng) Abstract: Rice occupies a significant acreage in Nepalese agriculture and is the main staple food
crop in Nepal. Fine and aromatic rice varieties have significant commercial value.
Allozyme electrophoresis has been a reliable technique in estimating the genetic
variation in crops. We surveyed isozyme variation of 40 aromatic/non-aromatic,
fine/coarse and cold tolerance rice varieties collected from Nepal and abroad including
Chhomrong land race as a check. SL"C enzyme systems were analyzed for allozyme
variability that detected distinct 14 isozyme loci and 33 alleles including null alleles.
The polym01phic enzyme systems: esterase (Est) revealed 12 phenotypes following
peroxidase (Prx) with 11, malate dehydrogenase (Mdh) with 7, alcohol dehydrogenase
rAdh) with 6 and, 6- phosphoglutanate dehydrogenase (Pgd) and acid phosphatase
fAcp) each with 4 phenotypes based on the combination of presence and absence of
alleles. All six enzymes !lystems were polymorphic among test varieties. Dendrogram did
not indicate any clear pattern of divisions of these varieties into definite clusters.
However three groups were detected at 58 % of similarity among 40 accessions. All
.Vepalese varieties except Lumle 2 clustered in a group for cold tolerance including
