Morphological characterization of district seeded rice landraces of foothills and river basin in far western development region / HK Prasai

Title : Morphological characterization of district seeded rice landraces of foothills and river basin in far western development region Material Type: printed text Authors: HK Prasai ; Subarna Sharma, Author ; Ujjwal Kumar Singh Kushwaha, Author ; Bishnu Joshi, Author Pagination: 188-191 p. Languages : English (eng) Keywords: Landraces ; Characterization Direct seeded rice Agro-environment Abstract: Numbers of rice landraces are grown by the farmers to fulfill their food requirement, socio econo
mic needs as well as cultural preferences through utilization exist ing heterogeneity in
so il , topograp hy and irrigation facility especially in far western Nepal. An experiment was
conducted during rainy season of 20 12 at Regional Agriculture Research Station, Bhagetada,
Doti as an attempt to characterize some of the direct seeded r ice landraces of foothi lls and
river basin agro-environment. The study was further intended in varietal improvement of the
local landraces for increasing productivity through effective selection techniques. For this
purpose, twelve indigenous lines of direct seeded rice were co llected from foothills and river
bas in areas of Doti and Dadeldhura districts. Cultivars were then evaluated in RCBD design
with three replications. Recommended dose of fertilizer and management practices were
appl ied. Morphologic al, Phenological and Yield attributing data were recorded and were
subjected to analysis through app lication ofMSTAT-C software. Cultivars were found nonsignificant
in traits such as; days to 75% flowering, days to 75% maturity, sp ike length, ti llers
per sq. m and unfilled grain per panicle. In contrast, s ignificant difference was exhibited
among these landraces in traits such as plant height, filled grain per panicle, Gra in Yield Kg
per hectare and I 000 grain weight. Cultivar Dal Badale and Naugire were signi ficantly taller
but Jhimma and Shyam jiro were found most dwarf. Latamandau Local showed significantly
higher average filed gra ins per pan icle but Shyam jiro and Dal Badalehave lower average
filled grain per panicle. Rate Dhan recorded significantly highest grain yield followed by
Anj ana; whereas cultivar Ghaiya local had lowest grain yield. Maximum I 000 grain weight
was recorded for Rate Dhan and Latamandau Local but Sunaulo exhibited the least test
weight.Link for e-copy: http://elibrary.narc.gov.np/?r=889 Morphological characterization of district seeded rice landraces of foothills and river basin in far western development region [printed text] / HK Prasai ; Subarna Sharma, Author ; Ujjwal Kumar Singh Kushwaha, Author ; Bishnu Joshi, Author . - [s.d.] . - 188-191 p.

Title : Characterization and utilization of rice germplasms in Nepal Material Type: printed text Authors: SR Gupta ; HB KC, Author ; Upadhyay, M.P., Author Pagination: 402-407 p. Languages : English (eng) Keywords: Genetic variation ; oryza rice landraces traits Abstract: Rice (Oryza sativa LJ is the main cereal grain and an important staple food crop ofNepal. It
is grown in a wide range of agro ecological regions where landraces and improved varieties
coexist. High level of diversity in the form of landraces and their wild relatives indicates the
richness . in the genetic variation. A total of 13 7 accessio.zs of rice landraces were
characterized for ·morpho agronomic traits using IPGRIJIRRJ descriptors at Khumaltar
during 200212003. Eight quantitative and six qualitative traits were recorded to assess the
diversity in agro morphological traits among these landraces. A range of variability was
observed among the accessions of rice landraces. Altogether 3107, 1728 and 2030
accessions of Nepalese rice germplasms are conserved in the gene bank of ABD, Khumatar,
IRRI and NIAR, respectively. Six varieties of rice were developed and released for
commercial cultivation using local landraces. The examined /andraces of rice have high
variability for agro morphological traits, which can be used in crop improvement
programme. Characterization, conservation and utilization of such valuable resources would
provide a sustainable basis for rice improvement in future.Link for e-copy: http://elibrary.narc.gov.np/?r=1129 Characterization and utilization of rice germplasms in Nepal [printed text] / SR Gupta ; HB KC, Author ; Upadhyay, M.P., Author . - [s.d.] . - 402-407 p.
