Abstract
A diallel test of crosses between sorghum (Sorghum bicolor (L.) Moenchv) arieties havingh igh, intermediate, and low levels of "recovery resistance" (tolerance) to the sorghums hoot fly, Atherlgona varia Meigen, showedt hat the inheritance of this character is complex. Additive gene action contributed most to the variation among entries in percentage of recovered plants, but specific and epistatic effects were also significant. The average heterosis was 11% for the single cross mean over the mean of the parents, andt he correlation betweeny ield andp ercentage recovered plants was very high. Cultivars ’Nama. tare’ and ’Serena’ proved valuable in the short-term breeding work, and populations (including derivatives of these cultivars) are being established for the longer term recurrent selection program. They should be effective in view of the largely additive genetic variance in recovery resistance.
