The performance of advanced sorghum lines under diverse environments

Abstract

The objective of this experiment was to evaluate, under three diverse environments, the performa nce of advanced
sorghum lines selected from uniform yield trials in 1995 and select stable high yielding, cultivars fo r further
evaluation. Released sorghum varieties Sekedo (brown seeded type) was included as a check variety. The trial was
conducted for two seasons in 1996 and 1997. Observations were made on yield, plant height, days to 50% flowering
and disease responses. Yields between four selected entries at Serere T.V.C, Bukedea T.V.C and Ngetta T.V.C and
aca·oss locations were not significavtly different from the checlc variety sekedo.AN 1/6/l/ produced the highest at
SAARI and across locations during 1996-1997 cropping season, however yields were generally lower in Bukedea
due to late planting, drought and severe sorghum midge attacks. AN l/6/11,3EX 88/1, LDRM 11/1/1 and 4MX/8 were
selected based on earliness, yield potential, for further evaluation and they yielded 9-25% over the check variety
Sekedo. The paper discusses the perfor·mance of only four selected advanced sorghum lines under diverse environments
over a period of two cropping seasons 1996 and 1997.
