Morphological variability and character assessment in mulberry hybrid (Kajli x Viswa)

R. Ravi Kumara, H. L. Ramesh

Abstract :

Breeding of mulberry is a herculean task and mixing and fixing of characters is still more complicated due to its heterozygous and cross pollinated nature. Crossing between the varieties is a routine process and evolving a new variety which surpasses and possess favorable traits superior to parents is of paramount importance. Kajli – a female parent crossed with male counterpart Viswa and the resultant First Generation Hyids showed considerably important variations in characters and was found FH–1>FH–2>FH– 3>FH–4. Growth and propagation parameters were encountered showing morphological improvement over the kajli and with varied modification in sex expression in different seasons in hyids. Surprise observation was presence of lobed and unlobed leaves in alternate nodes in FH–4 hyids. Kajli which completely possess lobed leaves, diploid in nature and viswa–a diploid with unlobed leaves
