Abstract
A dual purpose sorghum hybrid TNSH 482 derived from the cross ICSA 51 x TNS 30, evolved
with an objective to develop high yielding dual purpose hybrid with improved grain and
stover yield besides resistant to shootfly and grain mould was released as TNAU sorghum
hybrid CO 5. It is a medium tall, non-lodging and tan plant type hybrid which matures in 95 - 100
days and remains green even at maturity. The grains are creamy white in colour, borne on
medium cylindrical and semi-loose ear heads. It recorded an average grain yield of 2769 Kg/
ha under rainfed which was 13.16 and 17.03 per cent increase over the checks, COH 4 and MSH
51 respectively while its mean grain yield was 4338 Kg/ha under irrigation which was 17.18
and 13.32 per cent increase over the checks, COH 4 and MSH 51 respectively. The mean stover
yield was 7563 and 10548 Kg/ha under rainfed and irrigated situations respectively. The hybrid
TNSH 482 is resistant to downy mildew and moderately resistant to shoot fly and grain mould
disease.
