This experiment was carried out to obtain information on flowering pattern of Psidium, so that suitable species or varieties can be used in future breeding programme for their hybridization work to plan and develop crosses. The results revealed that cultivar Allahabad Safeda was earliest to bloom (24^th April) followed by Arka Amulya, Black guava, Hissar Surkha, Lalit and Snow White (25^th April), whereas L-49 (Sardar) was last to flower (10^th May). Flowering duration among guava genotypes differed significantly and it ranged between 39 to 52 days. The maximum flowering duration was observed in Lalit and Shweta (52 days) followed by Hisar Surkha (51 days), Sasni collection (51 days) and Arka Amulya (50 days), while, the shortest flowering duration was recorded in Hafsi Red (39 days). Thus, from the above findings it was noticed that the variation between the genotypes may be attributed to the differences in the genetic makeup of these genotypes. Observation and knowledge of such traits can guide a programme of genetic improvement, especially those pursuing derivation of varieties through hybridization programme. Also trees can possibly be exploited by cultural manipulation to flower and fruit when desired.
