Abstract

Oat (Avena sativa L.) is an important winter forage crop suitable for green fodder. Oat has also progressively contributed as a source for human consumption because of its nutritional attributes. Correlation coefficient and path analysis were done to determine the interrelationships and effects among the seventeen yield and quality traits. This will assist in selecting meritorious traits and formulating strategies to accomplish maximum yield potential along with genetic gain for quality attributes. The study was conducted on sixty two oat genotypes in an augmented design during Rabi 2019-20 at Research Farm Area of Forage Section, Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar. The analysis was done using R studio software 4.0.3. Positive and significant correlation of green fodder yield was recorded with dry matter yield, seed yield, test weight, peduncle length, number of leaves per plant, tillers per plant and plant height. Tillers per plant,
