Screening and Identiying Farmers’ Prefered Varieties for Adaptability and Resistance to Cassava Mosaic Disease (CMD) in Sierra Leone
Cassava plays an important role as a food security crop in Sub – Saharan Africa. However, yields of cassava in Sierra Leone are
generally low. Adoption of improved varieties resistant to the Cassava Mosaic Disease (CMD) which is one of the most limiting factors
of production remains low. Therefore cultivation of local varieties infected with the cassava mosaic disease dominates the farming
system in Sierra Leone.
Phyto-Nutrient Diversity in Morinda Citrifolia L. Genotypes of Andaman Islands, India
The Indian mulberry or Noni (Morinda citrifolia L.) is one of the emerging sources of natural antioxidants for herbal and pharmaceutical industry. The genus Morinda has more than 150 species in which M. citrifolia is identified as most important for health and economic point of view. Present study revealed significant (p < 0.05) diversity in 33 genotypes of M. citrifolia from Andaman and Nicobar Islands (India) for phyto-constituents. The promising genotypes viz. FRG-14, JGH-5, TRA-1, TRA-2 and HD-6 were identified for commercial uses. Correlation analysis in M. citrifolia germplasm showed strong correlation between carotenoids and ascorbic acid (r2 =0.973; p<0.05), tannin (r2 =0.598; p<0.05), flavonoids (r2 =0.691; p<0.05) and phenol (r2 =0.598; p<0.05). The genotypes showed wide range for antioxidant capacity which showed positive correlation with carotenoids (r2 =0.335; p<0.05), flavonoids (r2 =0.249; p<0.05) and Cu (r2 =0.953; p<0.05), Mn (r2 =0.953; p<0.05) and Mg (r2 =0.582; p<0.05). The diversity analysis is useful for designing breeding strategies for phyto-nutrient rich genotypes for better recovery in health products.
Programming Scripts for Simple and Complex Paternity Testing based on Open-Source Programming Language from the R Project
Programming scripts were written for the statistical analysis of genetic data from simple cases and complex cases of undetermined paternity. The methods presented here involve algorithms constructed with R, an open-source and increasingly popular programming language used for calculations and statistics; these methods also involve conditional probability analysis, Bayes’ Theorem, and pedigree analysis.
