7803-52. Lint fraction and micronaire of the two lines were similar to DES 422 but fiber length was 5% shorter. Fiber strength (T,) of Miscot 7803-52 was equal to DES 422 and 5% greater than Miscot 7803-51. Both lines are resistant to all known U.S. races of Xanthomonas campestris pv malvacearum (Smith) Dye, the causal agent of bacterial blight. Resistance of Miscot 780352 to fusarium wilt, caused by Fusarium oxysporum f. sp. vasinfectum (Atk.) Synd. and Hans., was equal to the resistant 'McNair 235', in the Regional Cotton Fusarium Wilt Test at Tallassee, AL. In tobacco budworm, Heliothls virescens F., resistance tests conducted at the USDA-ARS Crop Science Laboratory, Mississippi State, MS, both lines were more resistant than 'Stoneville 213'. In tests from 1985 to 1987, lint yields of Miscot 7803-51 were 27% higher than Stoneville 213 in larvae infested plots and 18% higher in larvae controlled plots. Concurrently, yields of Miscot 780352 were 36% higher than Stoneville 213 in infested plots and 21% higher in controlled plots. Seed (25 g) of Miscot 7803-51 and Miscot 7803-52 may be obtained from the Department of Agronomy, P.O. Box 5248, Mississippi State, MS 39762.
