Development of rapd-based scar marker related to fruit cracking in jackfruit (Artocarpus heterophyllus lam.)

A survey was conducted in the orchards of Department of Horticulture of UAS, GKVK, Bangalore and State Forest Department Farm, Tamaka at Kolar district, Karnataka, India. Study employed morphological and molecular markers for differentiating cracking and non-cracking types. The RAPD analysis identified OPC-07 as the polymorphic primer showing band size of 810 bp as the polymorphic marker. The sequence data of fruit cracking character were analysed for its identity using BLASTX search for its homology with the sequence of a gene already recorded in the database of the NCBI, Bethesda, USA. The nucleotide sequence data reported here have been deposited in Gene Bank (NCBI).
