Studies on Heterosis of F1 from Different Heterotic Combination with Ludahonggu Group's Inbreds as Father Lines in Maize

doi:10.7668/hbnxb.2007.S2.016

Abstract

Abstract: Five inbreds of Maize from different sources and their hybrids were used in the experiment.Through preliminary studies on the heterosis of F₁ with Ludahonggu group as father line,the results were as follows:The heterosis of F₁ from different heterotic combination between Ludahonggu group and Reid group,PA,PB groups were different to some extent,which changed with different characteristics;as father line Ludahonggu group influenced its descendants more than mother line;The application of different hybridism combinations between Ludahonggu group and other groups should be paid much attention when reforming hybrids through using different characters.

Key words: Maize, Heterosis, Germplasms, Hybridism models
