Combining abilities of the new Bc maize inbred lines
Seven new maize inbred lines were selected from the Bc Institute maize breeding program through tests with the line tester Mo17 (Bc11-7, Bc63473-13, Bc65073-4, Bc65741-28, Bc69110, Bc69111 and Bc720964). Combining ability of these lines was was estimated from hybrid combinations with three testers (Bc1511, Bc84 and Pa91) tested in field trial in Rugvica in 2010. Lines Bc11-7, Bc63473-13 and Bc65073-4 along with testers Bc1511 and Pa91 had positive effects for grain yield. The hybrid combination Bc720964 x Bc1511 had the highest grain yield 12, 39 t/ha with the SCA effect of 0, 715. Negative effect for grain yield was observed for tester B84, parent of low yielding hybrids except for the combination with line Bc11-7 whose SCA was highest (1, 177). This indicates that tester B84 was related to all investigated lines, excluding Bc11-7. Economically, the most valuable hybrid combinations were crosses with tester Bc 1511, one with the highest GCA effect (1, 140) for grain yield. Furthermore, an interesting combination is Bc11-7 x Bc1511 with the lowest grain moisture (27, 30 %) and the grain yield 11, 61 t/ha. However, the true value of the investigated combinations should be checked at more appropriate environment for FAO 600.
