General and specific combinig ability for yield in a diallel cross among 18 maize populations (Zea mays L.).
A study was carried out no diallel crosses among 18 maize populations. An analysis was conducted on ear weight data using Grigging's Method 2, Model I to determine general and specific combinig ability effects. General combining ability (GCA) was found to be significant but specific combinig ability (SCA) was not. Both location x GCA and location x SCA interactions were found to be significant. The results showed that populations CMS 06 and CMS 05 have the highest GCA effects. The cross (CMS 07 x CMS 10) gave the highest SCA effects.
