Description Trichomed, segregating and trichomeless F3 and F4 lines from four trichomed X trichomeless crosses and their parents were studied in the field in Patancheru. Compared with trichomeless lines, trichomed lines had significantly lower percentages of plants with Atherigona soccata eggs 18 days after emergence and of deadhearts at both 18 and 23 or more days after emergence. The ratio of the difference between the means of trichomed and trichomeless lines for the percentage of deadhearts to the corresponding difference between the parents ranged from 0.16 to 0.92 and exceeded 0.32 in seven of nine comparisons, indicating that trichomes were a major factor in resistance. Means of parents and progenies were regressed on four possible genetic models and results indicated that, besides trichomes, at least two loci that interact with each other were involved in resistance.
