For this reason, only OPVs have been recommended to Burundian farmers until today. With the current agricultural development and the need for intensification of the maize crop, the national programme has started a hybrid testing project taking into consideration the major stresses such as low N, stem borers and drought. During the 2000/2001 growing season, a trial composed of East and Central Africa drought and low N hybrids was carried out under medium stressed conditions at Moso research station; with the aim of evaluating the grain yield potential of good top crosses, three-way cross and double cross hybrids. Five commercial hybrids widely grown in East Africa together with the local1y recommended variety served as checks. The results indicated that the best hybrids were: LPSC3-36-2-2-1-1-B-B X CML 258/CML202, LPSC3-36-2-1-1-3-B-B- X CML258/CML206, P.72 reformed-s2-#-s2-##-1-1-2- 2-B XCML258/CML202, LA POSTA SEQC3-HI-2-2-2-1-1-#-#-B-B X CML254/CML202,LA POSTA SEQC3-H297-2-1-1-1- 2-#-#-B-B X SPL254-1-2-3-2-2-B/CML202.
