Abstract
Although the need for increased production of summer fodder is so keenly felt in Egypt, the plant breeders did not focused much of their attention to improv fodder teosinte as silage exchange for maize. In this study, an attempt was made in order to partition the genetic variance to its components for fodder traits through the evaluation of different generations (P1, P2, F1, F2, BC1, BC2) of the promising maize-teosinte crosses under two locations (El-Serw and Sids). The results indicated the presence of significant differences among crosses for all studied traits. Also, the results revealed the presence of significance of populations within crosses and each cross. The cross SC10 × Rayana ( R) was the highest among studied crosses for number of leaves (NL/P) (69.79), number of tillers (NT/P) (6.25), 5 th leaf area (5th LA) (643.56 cm2 ) green fodder yield per plant (GFY/p) (3740.0 g) and dry fodder yield per plant (DFY/p) (1191.13 g). While the cross SC 122 × R was the highest for crude protein (CP) (16.52 %), digestible protein (DP) (11.78 %) and total digestible nutrients (TDN) (67.25 %). The F2 generation of the three crosses in the two locations and their combined were less than corresponding values of F1 hybrids for all studied traits. This finding reflected the presence of non-additive genetic variance plays the major role in the inheritance of these traits. The results also revealed that, the backcross mean of most of studied crosses tended toward the respective recurrent parent, suggesting the role of additive and dominance gene action effects. Most of studied traits were significantly influenced by one or more type of epistatic effects, which included additive x additive ( aa ), additive x dominance ( ad) and dominance x dominance (dd ) gene action as appeared in the three studied crosses. In general, green fodder yield per plant (GFY/p) was positively with all other traits. Therefore, it wauld be concluded that the production of maize-teosinte hybrids is needed to be used as silage exchange for maize.
