Morphological characterization of <em>Lasia spinosa</em> (L.) Thw.: Screening of indigenous crop genetic resources for future food and nutritional security

Agricultural plant genetic resources (APGRs) are one of the pivotal sources for developing high yielding, stress tolerance varieties to sustain food and nutritional security of the world. Nepal has established National Agriculture Genetic Resource Centre (NAGRC), alias Genebank under the Nepal Agricultural Research Council (NARC) in Khumaltar premise in 2010 AD (2066 BS). NAGRC has been doing collection, identification, characterization, and regeneration of APGRs since its establishment. There are more than 11000 collections of APGRs in the Genebank. These accessions include cereals, pseudo cereals, pulses, oilseeds and vegetable of orthodox seed whereas crops having recalcitrant seed are conserved in the field Genebank, on-farm genebank and tissue bank. To analyze characters of new accessions, standard passport data are recorded and entered to accessions giving geographical locations and coordinates. The APGRs have been collected, cleaned, processed, preserved and regenerated and characterized according to the standard procedures and norms used by scientists across the world. Types of Genebank and options for effective management of APGRs in Nepal have explained in brief. This paper tries to explain the importance and management of APGRs with respect to sustain food and nutritional security of Nepal in coming days ahead.Agronomy Journal of Nepal (Agron JN) vol. 4, 2016, Page: 75-91

Mahalanobis Distances

Sustainability in livestock farming requires monitoring of autochthonous breeds which are well adapted to the local environment. The morphometric measurements seem to be the first approach which can provide useful information on the suitability of animal genetic resources for selection. In this work, thirteen morphometric variables were used for the phenotypic characterization of 130 adult autochthones cattle randomly selected from 30 local farms in Guelma. There were cases from four commonly accepted and traditional ecotypes: Guelmois, Cheurfa, Sétifien and Fawn. The results showed several and significant positive correlations between the different variables. Correlations were analyzed using Varimax orthogonal rotation PCA and three factors were extracted, which explain more than 75% of the total variation in the four ecotypes. Stepwise discriminant analysis showed that 6 of the 13 variables had discriminatory power to define the phenotypic profile of the ecotypes. Canonical discriminant analysis indicated that the Sétifien ecotype is separate from the other three ecotypes. Mahalanobis distances were significant between the different ecotypes except for the distance between the Guelmois and Fawn ecotypes. The cross-validation procedure assigned 91.42% of the Sétifien animals to their genetic group, while the percentages of animals assigned to the Cheurfa, Guelmois and Fawn ecotypes were 80.00%, 65.71% and 53.33% respectively. The multivariate approach has proven to be effective in differentiating the four ecotypes, with clear morphological differences from the Sétifien ecotype that may benefit from a genetic improvement program for more sustainable genetic resources preservation.

Food And Nutritional Security

Abstract With the global decline in capture fisheries, aquaculture remains alternative in bridging the gap and meeting the demand for fisheries products. Currently, aquaculture contributes approximately 50% of world total fishery production, hence becoming an important intervention in promoting food and nutritional security, and employment creation. Western Kenya is suitable for aquaculture production due to favorable climate and good soil as well as high demand for fish. The present survey purposed to assess the Socio-demographic characteristics of fish farmers, fish feed and seed producers in 9 Counties within Western Kenya. The information obtained included socio economic dynamics and challenges to fish farming. Fish farming mainly occur in rural areas in Western Kenya where the most dominant system is earthen ponds, measuring 300 m2. Aquaculture in the region is male dominated and majority of players practice individual enterprises. The majority of the hatcheries are authenticated and the lack of credit facility was mentioned as the most important challenge. However, for feed producers lack of adequate raw materials was the most important bottle neck. From this study, both environmental and social factors in the region must be synergized to achieve aquaculture sustainability. There is need for empowerment of farmers through capacity building and availability of credit facilities whereas hatcheries and feed producers must be empowered with adequate skills and infrastructure in order to adhere to good standards.
