Abstract
Three characters, peduncle inclination, peduncle smoothness and peduncle curvature were studied in an intervarietal cross in sorghum, SB 1066XIS 1515. Trihybrid ratio of 15: 49 was postulated for the first two characters. A ratio of 3: 61 was fitted for the third character. The factors I-Er and I-Wy showed genetic association with a recombination value of 25–84 map units, which were placed in the second linkage group. It is concluded that the characters—peduncle smoothness and peduncle curvature ave governed by three different pairs of genes and no environmental factors are involved.
