On the use of advanced generation hybrides as parents of double cross seed corn, a few investigators found that double crosses between F_1, F_2 or F_3 generations of single crosses produced essentially similar yields. The authbrs have inve-stigated this problem from the standpoint of seed production. The materials used in the experiment were single crosses, B 8XA 151, WF9 XM 14 and these parent inbred lines. In 1951, seeds of four inbred lines, two F_1 hybrids, two F_2 hybrids and four back-crosses were harvested.In 1952, these seeds were planted on field with three replications. Each replicati6n contained four groups and each group consisted. of inbred lines, F_1 hybrids, F_2 hybrids and back-crosses, respectively. Groups were arranged at random in replications.The results obtained as follows :-
