Path coefficient analysis of the first order and second order component of fodder yield in oats (Avena sativa L.)

Abstract

Thirty two varieties of oats were analysed for correlation coefficient between 14 characters which enabled the path coefficient analysis of the first order and second order components of dry matter yield in fodder oats (Avena saliva L). The analysis revealed that number of tillers, leaf area and number of leaves had major roles in the accumilation of dry matter yield through the first order components, namely, green weight of stem and green weight of leaves. The results indicated that by the improvement of these characters, the dry matter yield also could be increased.
