Correlation and path analysis in forage maize (Zea mays L.)

摘要

Correlation and path coefficient analysis was carried out in 59 genotypes (42 hybrids and 17 parents) of forage maize for 10 component characters including green fodder and dry matter yield Except crude protein content and neutral detergent fibre, alJthe component characters had significant and positive correlation with both the types of yield (green and dry). Path coefficient revealed that the characters dry matter yield per plant, number of leaves per plant, days to 50% si Iking and plant height had positive direct effects on green fodder yield. This indicated that these characters were the most important characters to be considered for selection to bring about an improvement in yield. The indirect effect of these characters via other characterswas also positive.
