The tissue culture protocol standardized was used for mass multiplication of
high yielding disease free (YLD resistant) arecanut palms. Inflorescence
explants from disease free palms of age 40 years in farmers’ gardens from hot
spot areas in Sullia regions of Karnataka were sampled. Large number of plants
was obtained in vitro. Direct somatic embryos from inflorescence rachilla was
also obtained, which is a first report. The incidence of YLD had devastated the
arecanut growing tracts and only by replanting with resistant planting material
the gardens could be rejuvenated. In this context the developed tissue culture
protocol has immense field application. The successful development of arecanut
tissue culture protocol has opened up new hope in resistance breeding as even
with limited number of resistant genotypes, large number of planting material
could be produced and distributed among farmers. Besides, large number of newly
released dwarf-hybrids can also be produced and distributed among farmers. |
