Determination of genetic variability for physiological traits related to drought tolerance in African rice (Oryza glaberrima)
Relative water content, water potential and transpiration of Africa rice (Oryza glaberrima) were investigated in a controlled condition under phytotron. Two Oryza sativa cultivars, IR55423-01 (a drought tolerant genotype) and IR64 (drought sensitive genotype) and 8 O. glaberrima accessions were grown under droughted and watered conditions. The fraction of transpirable soil water (FTSW) was...

Selection of yam seeds from open pollination for adoption in yam (Dioscorea rotundata Poir) production zones in Nigeria
Yam improvement through hybridization has suffered a lot of challenges over the years. Poor or non flowering of candidate parents, lack of synchrony in flowering of male and female genotypes, flowering intensity that varies with season and location, pests and diseases and other factors have serious obstacles limiting progress in yam hybrid production. This paper discussed the origin, germination and...
