Abstract Late root bulking is a major factor leading
to rejection and abandoning of improved cassava
genotypes in sub-Saharan Africa. Early bulking (EB)
varieties shorten the growth period from planting to
harvesting, better fit into environments with short
rainy season, and reduce exposure to biotic and abiotic
stresses thereby increasing productivity. This study
was carried out to identify molecular markers linked to
EB in cassava. Nine cassava hybrid populations
(COB-1–COB-9) were developed using six elite
varieties (TMS 30572, TMS 97/2205, TMS 98/0505,
TMS 30555, NR 8212 and NR 8083) from the African
cassava germplasm as parents. The progeny in each of
the nine populations (101–272 genotypes per population)
were evaluated for EB at 7 months after planting
