1. The present findings are useful to breeders in selecting the potential parental materials for maize improvement programs in mid altitude agro-ecological zones in Kenya. For grain yield improvement test crosses MUL508 x MUL688(entry 9), POPA x MUL141(entry 19), MUL513 x MUL114 (entry 31) and MUL513 x CN244 (entry 33) can further be evaluated and eventually released to farmers as they indicated promising relationship with yield potential compared to other test crosses. Test crosses MUL508 x MUL516 (entry1), POPA x MUL141 (entry 19) and POPA x MUL688 (entry 26) can further be evaluated for disease resistance. Inbred line MUL 513 can further be evaluated for grain yield improvement with all the other inbred lines which had high grain yields.
2. Inbred lines MUL 508, POP A and MUL513 can be used in improving other genotypes on disease resistant trait.
3. There is also need for further study of the inbred lines used in this study for stability and adaptability in other counties in Kenya.
