2014
Manigandan, S | Vijayakumar, R.M.
Soursop is an important crop is seen only in neglected conditions in the farm boundaries and uncared lands. To exploit the potential of the trees with this objective, a survey was undertaken in several villages for the naturally occurring soursoptrees, which are of seedling origin. A total number of 22 trees were studied which had shown considerable phenotypic variation in morphological and phenological traits. A structured questionnaire supplemented by oral interviews and IPGRI guidelines was used. Among the 22 accessions, notable variations were observed in tree shape, trunk colour, trunk ramification, colour of young branches, leaf blade shape, pulp colour and taste. Generally, soursop genotypes showed good adaptation to the specific soil and climate conditions of these regions and great variability was found among them. There is a growing awareness particularly about the anti cancer properties of this plant among the people and the consumption of this fruit and leaves by the cancer-affected patients is on the increase. So, it has become necessary to document the trees available in Tamil Nadu and variations them to exploit the potential of the trees.
