Combining ability type of analysis for triallel crosses in maize (Zea mays L.)

Summary

Data on 30 three-way maize (Zea mays L.) hybrids formed from 5 inbred lines were subjected to the combining ability type of analysis. The relative importance of general and specific line effects in maize three-way hybrids was studied by the Ponnuswamy and Das (1973) method. It was also shown that this analysis provides the breeder with the basic information necessary to choosing proper breeding materials and in deciding the order in which they should be combined to get desirable three-way hybrids.
