Abstract
A dual purpose sorghum culture TNS 598 (hybrid derivative of the cross APK 1 x TNS 291)
developed with an objective of combining high grain and fodder yield was released as TNAU
sorghum CO 30. It is a tall growing non-lodging tan plant type variety, matures in 100 - 105 days
and remains green even at maturity. The grains are creamy white in colour, borne on medium
cylindrical semi-compact ear heads. It recorded an average grain yield of 2805 Kg/ha under
rain-fed with 20.7 per cent and 19.3 per cent increase over CO(S) 28 and APK 1 respectively
while its mean grain yield was 3364 Kg/ha under irrigation which is 19.2 per cent and 23.7 per
cent increase over CO(S) 28 and APK 1 respectively. The mean stover yield was 6988 Kg/ha and
9292 Kg/ha under rain fed and irrigated situation respectively. The culture TNS 598 is resistant
to downy mildew and moderately resistant to shoot fly, stem borer and grain mould disease.
