| Abstract:
Molecular maps of mango have been constructed. A population of 31 plants from a cross between cultivars ‘Alphonso’ and ‘Palmer’ were generated at the Pakchong Horticultural Research Station as a part of mango breeding program. One hundred and ninety-seven RFLP markers derived from the Pst I genomic library of a cultivar ‘Nang Klang Wan’ together with 650 loci of AFLP markers segregating for each parental loci were used to construct linkage maps corresponding to pseudo-testcross scheme. All of the calculation were performed using the Mapmaker linkage analysis program. Three hundred and sixty-five loci segregating for Alphonso loci were grouped into 63 groups with the average of 3.3 markers per group covering 1437.7 cM (average 10. 4 cM interval). Three hundred and sixty-nine markers corresponding to Palmer loci were grouped into 59 groups with the average of 4.2 markers per group (average 7 cM interval). | |
