Graded visually on a scale of 1 (no fuzz) to 8 (very dense fuzz), seed-coat grades in E790, F962, and H314 were 5.2, 5.6, and 5.4, respectively, compared with 4.0 for BPA75. Micronaire units were 4.9,5.5, and 5.7 in E790, F962, and H314, respectively, compared with 4.4 in BPA75. These germplasms have leaf and stem pubescence similar to BPA75. Such high pubescence is associated with resistance to jassid (Empoasca spp.) (3). Breeder seed will be maintained by the National Fibre Research Centre, KARI, Kibos, Kenya. Small quantities of seed (25 g) of these lines are available for distribution upon written request to the corresponding author.
