At Mwele site, the maize materials were also compared for yield performance under no and with Striga infestation during the short rainy season. From early open pollinated materials, maize entry 98 Syn WEC supported the lowest Striga numbers. On yield performance, maize entries EV.DT 97STR C1 and TMV-I produced the highest grain yield under Striga infestation. There were significant percentage yield loss differences among the maize entries tested and TMV-1 had the lowest yield loss. From late/intermediate open pollinated maize cultivars combined from both short and long season results low Striga counts were recorded from maize entries TZ 96 STR Syn.-W, IWF STR CO and Z. diplo. BC4C2 and the highest grain yield was obtained from entry 9022-13 (Res. Hyb.). At Melela site, a hot sport for S. asiatica and S. forbesii, late/intermediate maize entry TZ96 STR Syn-W supported the lowest S. forbesii numbers but the highest grain yield was produced by maize entry STR EV.IWF.Collection: CIMMYT Publications Collection
