Development of interspecific hybrid progenies of mango and their characterization

Abstract

A total 26 interspecific mango hybrids population were obtained from the crosses involving Alphonso, Amrapali and NR34 as a female parents and Mangifera odorata Griff, as male parent. Morphological traits revealed that all the interspecific hybrids as well as parent trees were found to be erect and also spreading habit with circular, semicircular and oblong crown shape. The results of cytological studies showed that interspecific hybrids were also possessed the same somatic chromosome number 2n = 40 as that of mango. Most of the interspecific hybrids showed the intermediate to dense foliage density. Out of 11 SSR markers, three primers showed high polymorphism and confirmed the hybridity based on the allelic range variation among the four parental mangoes.
