Abstract
To study correlation and path analysis for yield and its attributing characters ten forage and silage summer forage crops were evaluated at Sakha Agricultural Research Station in 2020 and 2021 summer seasons. the studied crops were seven summer forage crops (three cuts) and three summer forage crops (only one cut). Highly significant differences were detected among the seven genotypes over the two seasons for plant height, stem diameter, fresh yield, dry yield at the three cuts over two seasons and their total fresh and dry yields. Highly significant differences were found among the three crops for silage fresh, dry yield and its components in the combined analysis. Correlation coefficients were highly significant in positive direction between fresh forage yield cut 1, 2, 3, total fresh yield, dry yield cut 1, 2, 3, total dry yield, plant height cut 1, 2, 3, stem diameter cut 1, 2 and cut 3 implying the effectiveness of these traits in selection for fresh forage yield. In addition, insignificant negative estimates of correlation coefficients observed between fresh forage yield cut 1, 2, 3, total fresh yield, dry yield cut 1,2,3, total dry yield, plant height cut 1,2,3, stem diameter cut 1, 2 and cut 3 and each of fresh leaf stem percent cut 1, 2, 3, LI%, SI and TI% traits, indicating that selection of low LI%, SI and TI% contribute to high estimates of these characters. Highly significant and negative estimates of correlation coefficients observed among fresh leaf stem percent
