Observations on Seedlessness, Fruit Development and Cytology of Varieties of Guava

Abstract

The cultivated guava commonly grown for its edible fruits, exists in varied forms and a number of varieties are known in cultivation (Hayes, 1957; Sham Singh et al., 1963). Diploid, triploid and aneuploid forms of Psidium guajava L. have been reported (Atchinson, 1947; Kumar and Ranade, 1952: D'Cruz and Babu Rao, 1962; Majumdar and Singh, 1964), but cytological studies to reveal the relationship between morphological variation, sterility and polyploidy have been meagre. The investigations reported herein were directed towards an examination of these aspects in respect of the local country guavas and commercial varieties.
