Farmers’ participatory selection for early bulking cassava genotypes in semi-arid Eastern Kenya

  Cassava is an important food security crop in semi-arid, Eastern Kenya, but production is constrained by planting late bulking landraces. Therefore, farmer participatory variety selection was initiated with the aim of identifying early bulking varieties with preferred root qualities. Four popular local varieties were crossed with six early-bulking varieties selected from IITA germplasm in a North...

Genetic diversity analysis in different varieties of black gram using RAPD markers

  The molecular marker is a useful tool for assessing genetic variation and resolving cultivars identities. The objective of the present study was to investigate the genetic diversity and relationships among 8 black gram (Vigna mungo) varieties from diverse geographic locations of U.P. and Andhra Pradesh, (India) using random amplified polymorphic deoxyribonucleic acid (RAPD) markers. Forty decamer -...
