“…A number of priorities for actionwere identified: (a) simple and low cost strategies to estimate production andplanted areas and the extent of serious pest and disease threats to guide investmentin areas with the greatest impact; (b) mapping of production potential based onsoils, climate and water sources and ease of market access to prioritize investment inintensification; (c) piloting of clean seed systems to contain the spread and impact ofBanana bunchy top virus, and Xanthomonas wilt, to multiply highly productiveclones of preferred cultivars and to conserve plantain diversity; (d) technology forland productivity stabilization and improvement, depending on access toinfrastructure and natural resource quality; (e) improving field access toinformation on new technologies to farmers and their associations, public extensionand non-governmental organizations and rural school teachers; and (f) farmer andvillage marketing organizations to capture greater value from plantain and bananamarkets where clean seed and improved land productivity are piloted.…”

Optimum time for collection of root samples for chromosome observation in yams (Dioscorea spp.) by Babil, P.K., Kikuno, H., Shiwachi, H., Toyohara, H., Fujigaki, J., Fujimaki, H., Asiedu, Robert

“…The objective of the present study was to develop an efficient method of chromosome observation by identifying the optimum time for collecting root samples containing large numbers of metaphase cells. In the present investigation, two breeders’ lines developed at IITA, TDa 98/01183 (D. alata) and TDr 95/18544 (D. rotundata) which were identified as tetraploids (2n = 4x = 40) were used. …”

Morphophysiological diversity of rhizobia nodulating pigeon pea (Cajanus cajan L. Millsp.) growing in Ethiopia by Degefu, T., Woldemeskel, Endalkachew, Adem, M., Fikre, Asnake, Amede, Tilahun, Ojiewo, Christopher Ochieng

“…The dendrogram constructed from cluster analysis of 91 phenotypic traits, grouped them into six clusters and eight un-clustered positions at 80% relative similarity. Cluster I contained 83% of the test isolates that were grouped together with the reference strains Bradyrhizobium japonicum (HAMBI 2314T) and Bradyrhizobium elkanii (LMG 6164), suggesting that pigeon pea is commonly nodulated by bradyrhizobia. …”
