dc.description.abstractAnnona belongs to the family Annonaceae, which comprises about 120 genera with 2000 species.Annonaceous fruits are characterized by a serious problem of fruit set and assisted pollination is commonly practiced for improving the set. Four species of annona;- Annona squamosa L,A. atemoya Hort,A. cherimola Mill and A. reticulata L. were used to study the metaxenic effect. Results showed that maximum fruit set was recorded when A. squamosa L. (81.73 %), A. cherimola Mill (82.86 %) were crossed with the pollen of A. reticulata L. and A. atemoya Hort. (97.54 %) A. reticulata L. (69.66 %) were crossed withA. squamosa L. In another study, four hybrids were evaluated for fruit yield, quality and selffruitfulness.Results showed that Arka Sahan (54.85 kg/tree)performed well with assisted pollination, whereas the Hybrid 19/26 (48.64 kg/tree)and Hybrid 16/14 (48.99 kg/tree)wererated as very goodfollowed by Hybrid 16/10 (21.66 kg/tree) rated as good under natural pollination. Chromosome number, floral biology and hybridity confirmation of hybrids and their parents were studied and the results showed that the somatic chromosomes were 7 (2n=14) in all interspecific hybrids including Arka Sahan and their respective parents.Pollen viability, pollen fertility, pollen germination were found relatively maximum in the parents than in their hybrids. Thestigma receptivity was found maximum on the day of anthesis in the early morning.ISSR UBC- 826 primer clearly confirmed the hybridity of different annona hybrids.en_US
