Title : Variability and crossability study on cultivated and wild species of rice (Oryza sativa L.) Material Type: printed text Authors: SR Gupta, Editor ; Upadhyay, M.P., Editor ; B.K. Joshi, Author ; Bista, S., Author Publisher: Hardinath, Janakpur : National Rice Research Programme Publication Date: 2010 Pagination: 125-131 p. Keywords: crossability morphological traits ; variability wild rice Abstract: Two wild rice species, Oryza nivara and 0. rufipogon, four improved varieties and two landraces were used to study the
morphological variation and crossability between them during 2004/05 and 2005/06 at Khwnaltar. Data on nine quantitative and
fifteen qualitative traits were recorded to characterize and assess the diversity. Variations in legule length (5.8-29mm). heading days
(64-90 days), culm length (46.2-114.4cm) culm number (14.2-59) for wild rice and 1.44-3Il1Ill, 105-132days, 88.6-136.8cm, and 7.2-
15.8 respectively were observed in cultivated rice. The qualitative traits also showed greater variability between wild and cultivated
rice. Out of fourteen crosses between 0. sativa and two wild rice species, the highest crossability (41.86%) was observed in Jumli
marsi and 0 . nivara cross and the lowest crossability (2.56%) in Chainung-242 and 0. rufipogon cross were observed. Variation in
crossability ranged from 2.56-41.86 percent The examined wild and cultivated rice varieties have high variability for morphological
traits, which can be used in crop improvement programme in future.Link for e-copy: http://elibrary.narc.gov.np/?r=1009 Variability and crossability study on cultivated and wild species of rice (Oryza sativa L.)

Title : Variability of Cochliobolus sativus isolates from Nepal Material Type: printed text Authors: Mahto, B.N., Author ; Bhusal R.P, Author ; Pokharel R, Author ; Gurung S, Author ; Adhikari T.B, Author Pagination: 320-330 p. Languages : English (eng) Keywords: Foliar Blight, Isolates, Variability Abstract: Spot blotch, caused by Cochliobolus sativus, is a major disease of wheat (Triticum aestivum L.) in Nepal. A total of 48 monoconidial isolates of C. sativus collected from different locations in Nepal were analyzed for cultural and morphological characteristics. Among them, II isolates (CS 2 (hill), CS 9 (hill,) CS JO (hill), CS 12 (hill), CS 15 (hill), CS 17 (hill), CS 19 (hill), CS 24 (hill), CS 33 (plain), CS 37 (plain), and CS 45 (plain)) varied greatly in colony appearances such as color of the substrate, margin, z.onation, sectoring, and exudation. These 1 1 isolates plus CS 32 (plain) and CS 49 (plain) were selected and evaluated for virulence on eight wheat genotypes (Chirya 1, Chirya-7, Milan/Shanghai?, SW 89-5422, PBW 343, BL 1473, BL 3036, and RR 21) at the seedling stage in a greenhouse............

Title : Conservation and characterization of finger millet (Eleusine Coracana L.) Germplasm in Nepal Material Type: printed text Authors: SR Gupta, Editor ; Upadhyay, M.P., Author Publication Date: 2010 Pagination: 285-291 p. Keywords: Characterization ; finger millet germplasm traits and variability Abstract: Finger millet (Eleusine coracana L.) is the main diet of hill fanners. Nepalese farmers have consumed, maintained and use finger
millet diversity over time and space. Altogether, 879 landraces of finger millet have been conserved in the genetic seed house at
Agriculture Botany Division, Khumalrar. Among them, 196 accessions were characterized for morpho agronomic traits using
IPGRIIIRRI descriptors at Khumaltar, \alitpur during 2004/05 and 2005/06. Measurements on quantitative and qualitative traits
were recorded to estimate the diversity in agro morphological traits. A range of variability was observed among the accessions of
finger millet landraces. Variability for maturity (94-148 days), leaf blade length (9.6-41.8cm) and finger length (2.40-12.60cm was
observed. Three vatieties of finger millet have been released for commercial cultivation using local landraces. The examined
landraces of finger millet have shown high variability for various agro morphological traits which can be used in crop improvement
programme. Conservation, use and management of these valuable resources would create a sustainable basis for finger millet
