Public ISBD in Rice research in Nepal : Proceedings of 24th National Summer Crops Research Workshop, Khumaltar, Lalitpur, 30-31 June 2004 / Adhikari, N.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.

Conservation and characterization of finger millet (Eleusine Coracana L.) Germplasm in Nepal / SR Gupta    

Public ISBD in Summer crops research in Nepal: Proceedings of the 25th Summer Crops Workshop held at Kathmandu 21-23 June 2007 / Adhikari, N.P.     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 _. improvement in Nepal.

Public ISBD in Summer crops research in Nepal: Proceedings of the 25th Summer Crops Workshop held at Kathmandu 21-23 June 2007 / Adhikari, N.P.     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.
