EVALUATION OF TETRAPLOIDS FOR TRIPLOID BREEDING IN MULBERRY

Published on

Thirty tetraploid mulberry genotypes were evaluated to select desirable donors for
breeding purpose. Morphological, anatomical and leaf yield characteristics were studied
for two years. Subsequent ranking analysis on the basis of leaf yield, leaf thickness,
spongy layer thickness, cystolith and stomatal frequencies, leaf moisture and moisture
retention capacities of harvested leaves revealed that tetraploids T36, T21, T13, T19
and T4 were superior for most of the traits. These genotypes can be used for directional
breeding programmes to evolve high yielding triploids.
