Summary, etc. Fifteen maize (Zea mays L.) hybrids and one open pollinated variety, Kgalagadi Early Pearl (KEP), were evaluated for two seasons at three locations in 1993/94 and 1994/95. The study was undertaken to provide information on yield stability and performance of hybrids in Botswana environments. Genotype x environment (GCS) interactions were analyzed using the additive main effects and multiplicative interaction (AMMI) with principal components analysis (IPCA 1). They were significant (p<0.01) for days to 50 % silking, days to 50 % anthesis, anthesis silking interval (ASI) and plant height, but not for grain yield. Hybrids PHB 3427, PHB 3435, CRN 3839, CRN 4141 and CRN 4523 were significantly, higher in yield (p<0.01) than KEP. Number of days to 50% silking (r = -0.785) and days to 50% anthesis (r=-0.776) were negatively correlated with grain yield. Plant height was highly and positively correlated with yield (r=0.783). Hybrids with short ASI seemed to perform better compared to those with longer ASI. Environment was found to play a major role in determining the grain yield across seasons and sites but hybrids were consistent across seasons and locations.
