Morphology of floral compatibility among some mango cultivars [electronic resource].

Includes reference.

Four mango cultivars namely Hindi Be Sinnara, Pairi, Alphonso and Mabrouka were used to study morphology of pollen compatibility among the four cultivars and relationship of mating system among the four cultivars with fruit set under Assiut environmental conditions during 2005, 2006 and 2007 seasons. Results showed that pollen germination and tube growth take 4 days to reach the stylar base. Selfing of either cultivar induced lower number of pollen tubes at lower number of pollen tubes at outcrossing (open and crossing to other cvs.) and as a result, complete fruit drop occurred when the 4 cultivars were pollinated by hand selfing; hence there is self-incompatibility in all 4 cultivars. Cross pollination between Alphonso and Mabrouka cvs. resulted in alternatively improved fruit retention. On the other hand, Alphonso cv. was a high fertile pollinator to Hindi Be Sinnara cv., which in tum was a high fertile pollinator to Pairi cv. So, this study recommends that these four cultivars should be accordingly cross pollinated to get a heigher yield.
