Abstract

Abstract: This study was carried out to analyze the combining ability of inbred lines from maize landraces in order to provide the theoretical basis for assessing potential value of inbred lines.The materials included 11 testers, which used commonly in Southwest regions, 17 newly inbreds obtained from maize landraces, and 187(17×11) combinations which were crossed with 17 new maize inbred lines and the 11 testers by NC Ⅱ mating design.The combining ability of 17 inbred lines from landraces was analyzed based on the date for the experiment.The genetic parameters were done basing on combining ability.The results showed that P1-1, P1-16 and P1-14 with the better comprehensive characters can be directly used in maize breeding program.The SCA of P2-4×P1-10 was high in most traits, they brought out strong heterosis.GCA variance was bigger than SCA variance in plant height, ear height, rows per ear etc four characters, yet SCA variance of ear length, sterile length and 100-kernel weight etc five characters was bigger than GCA variance.So these characters were selected would be based on their heritability.For example, plant height, ear height, rows per ear etc can be selected in early stage, ear length, sterile length and 100-kernel weight etc ought to be selected in lately stage.We should pay attention to GCA, SCA when cross elite hybrid combinations.

Key words: Maize, Landraces, Inbred lines, Combining ability, Heterosis, Genetic parameters
