Title : Effect of floret position and 2, 4-d application in maize mediated polyhaploid embryo production in wheat Material Type: printed text Authors: R.K. Niraula, Author ; B.P Sah, Author Pagination: 224-231 p. Languages : English (eng) Keywords: Dihaploid, Embryo, Seed Set, Spikelet Culture, Tiller Injection, Wheat x Maize Crosses Abstract: In order to increase the efficiency of embryo yield for wheat haploid production through wheat x maize crosses, effect of floret positions and various methods of 2, 4-D application were investigated. Wheat genotype 'WK P04' was used as female while maize cultivar 'Khumal Yellow' as pollen parent. The experiments consist of 3 floret positions: upper, middle and lower portion of spike and various methods of 2, 4-D application: spikelet culture, tiller injection, detached-tiller, spray, cup-filling, and dipping. Except spikelet culture and control each treatment was provided with I 00 ppm 2, 4-D. Effect of floret positions and 2, 4-D treatments on the recovery of embryos were significant. The middle portion of spike was superior for all the tested parameters. Higher embryo forming efficiency (20.74 percent) was obtained using spikelet culture method due to the availability of favorable cultural conditions.....................

Title : Effect of integrated practices on foliar blight management in wheat Material Type: printed text Authors: Mahto, B.N., Author ; B.P Sah, Author Pagination: 309-313 p. Languages : English (eng) Abstract: Foliar blight (HLB) was found significantly less, by applying two irrigation as compared two one irrigation. High seed rate @ of 150 kg/ha against 120 kg/ha had not measurable effect of HLB (AUDPC)Area Under Disease Progress Curve at flag leaf and whole plant. Foliar blight development and irrigation were observed negatively correlated either on whole plant and flage leaf Thousand grain weight (TGW) and grain yield (kg/ha) were also found to be highly negatively correlated with A UDPC on flag leaf as well as on whole plant.

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 : Level of resistance in selected wheat genotypes against helminthosporium leaf blight Material Type: printed text Authors: Mahto, B.N., Author ; B.P Sah, Author ; H.P Bimb, Author Pagination: 315-323 p. Languages : English (eng) Abstract: Tested wheat genotypes were found resistant at Bhairhawa condition. The ratio of unsprayed/sprayed appear useful to detect yield loss associated with foliar blight (HLB) and could help identify to/ranee as well as resistance. Grain yield loss was found from 3.1 to 23.8 percent. A UDPC was observed low in resistant genotypes and was used to measure the effects of HLB. Yield and other yield components were negatively correlated with AUDPC. However ,TGW was positively correlated in 1992.
