Abstract

The general variation pattern in 6 metric traits of 30 mulberry varieties was studied under uniform agroclimatic conditions for four consecutive years. The range of variability encountered in these characters was from 14.98 m to 30.71 m for total primary branch length/plant, 17.76 to 2933 nodes/metre for primary branch length, 1.23 m to 1265 m for total secondary branch length/plant, 34.61 to 96.94 nodes/metre of secondary branch length, 8658 cm² to 20751cm² for leaf index and 1.203 kg to 4.675 kg for leaf yield/plant. The leaf yield had significantly positive correlation with the number of primary branch nodes and leaf Index.

Abstract

The general variation pattern in a number of metrical characters including diosgenin content in tubers of Dioscorca deltoidea Was studied in different populations covering entire Dioscorea growing forest area of the Jammu and Kashmir State. The mean, range, standard error and co-efficient of variation of twenty traits studied, revealed a great magnitude of variation amongst various populations. The underlying causes for such a huge variation are discussed.
