Varietal response for in vitro shoot development in mulberry (Morus spp.)

Abstract

A study was undertaken in the department of sericulture, with an objective to study the genotypic variations for the regeneration potential and to standardize the culture media for regenerates from nodal explant of different varieties of mulberry. The maximum bud sprouting (72.57%) was noticed in M-5 when MS medium with different concentrations of NAA and BAP. Among the different concentrations and combinations highest auxillary bud sprouting percentage of 71.50 was recorded when MS medium supplemented with 1.5 and 1.0 per cent NAA and BAP respectively in M5. In another combination of IAA and BAP, Significantly maximum response of sporting percentage (77.52%) was recorded in S13 when compared to V1, M5 and Mysore local. On the other hand among the different concentrations and combinations used the highest sprouting percentage of 81.91 was recorded when MS medium is supplemented with different concentrations of 1.5 and 1.0 mg/l IAA and BAP respectively.
