Abstract:

Correlation studies with 21 maize hybrids indicated that cob length, number of kernel rows per cob, 100 seed weight, and Harvest index showed significant positive association with grain yield per plant both at phenotypic and genotypic levels. Path analysis studies revealed that biological yield and harvest index exerted maximum positive direct effect followed by cob length, plant height and protein content on grain yield per plant and grain yield per ha.


Keywords: Character association, Path analysis, Yield, Maize.
