Abstract: Genetic diversity among 64 CIMMYT and BARI developed maize inbred lines was conducted at the research farm of Plant Breeding Division, Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur, Bangladesh during Rabi season 2012-13. The genotypes were grouped into six clusters. Cluster III comprised the maximum genotypes (18) which indicated the genetic similarity among them. The minimum genotype (4) was contained in the cluster V. The highest inter-cluster distance was observed between cluster VI and III (9.37) followed by cluster VI and V(8.22) and cluster V and I (7.75) suggesting wider diversity between them and the genotypes in these cluster could be used as donor parents for new maize hybrid development. The highest intra-cluster distance was observed in cluster V (0.846) and the cluster II was had the least intra cluster distance (0.472). The mean values of cluster VI recorded the highest for thousand seed weight (360.80 gm) and yield per hectare (4.72 ton/ha). It appeared that the early maturing genotypes were included in the cluster V (147.75). The positive absolute values of the two vectors revealed that ear height, ear diameter and yield (t/ha) had the greatest contribution to genetic divergence. The negative values for the two vectors for days to 50% tasseling, ear length and thousand seed weight (TSW) indicated the least responsibility of both the primary and secondary differentiations.

Abstract: A study of Tamarindus indica fruits rot was carried out in Maiduguri Monday Market located in The North- Eastern Nigeria. Tamarind indica fruits are showing sign of spoilage and fresh one were collected to ascertain the presence of contaminant and pathogenicity test was carry out to confirm further the fungal pathogen associated with fruits rot. We assessed the effects of temperature on the growth of colony diameter of the isolate. In vitro radial growth of each species of the fungal isolates (Aspergillus niger, Rhizopus stolonifer, Ulocladium chartarum, Penicillium chrysogenum and Penicillium citrinum) was measured at 37°C, 42°C, 47°C, 52°C, and 57°C for three weeks. Optimal growth for all the five-species occurred at 37°C, with slower growth at 47°C and 52°C. At 57°C, values of colony diameter reduced significantly for all the fungal isolates observed, however, there was a close relationship in values of colony diameter obtained for all the fungal species at 57°C. After three weeks, fungal colonies were digitally photomicrographed and colony opacity was assessed.

Abstract: Food insecurity and malnutrition affect much of the world’s population. Wild edible plants are known to make important contributions to the livelihoods of local communities of sub-Saharan Africa countries including Ethiopia. The populations in Ethiopia have a rich knowledge of consumption of wild edible plants and wild edible plants are still an integral part of the society in the country. An Ethnobotanical Survey of Wild Edible Plants Commercialized in Kefira Market, Dire Dawa City, Eastern Ethiopia was conducted with the aim of documenting the wild edible plants used by the community. Ethnobotanical data were collected from 29 informants using semi-structured interviews. A total of 22 wild edible plants belonging to 17 families were documented. Most of the wild edible plants were trees (81.82%), Fruits were the dominant edible parts (68%) followed by seed (18%) consumed by the people. The present paper provides basic information for better conservation, possibly for further exploitation of WEPs, and to preserve the traditional knowledge associated with WEPs for the future generation.
