Studies on Flowering Characteristics and Floral Morphology of Some Jamun Genotypes (Syzygium cuminii Skeels) under Semi-arid Lateritic Belt of West Bengal, India

Abstract

A study was conducted to find out the variability of flowering behaviour and floral morphology of randomly selected 10 jamun genotypes (Syzygium cuminii Skeels) from 3 diferent districts namely Bankura, Purulia and Paschim Bardhaman under semi-arid lateritic belt of West Bengal during the year 2022. Only a single plant was considered for a single accession which was taken under the study.  The selection was done on random basis. Significant variation has been observed among the genotypes for the flowering behaviour as well as morphological characters of flowers. Month of panicle emergence among the selected genotypes ranged from 1st week of March to last week of March. Time taken for bud development was observed 21 (days from panicle emergence) from three accessions like JA 9 was shortest among 10 jamun accessions studied. Longest time for bud development was observed in JA 4 (38 days). Duration of flowering was highest of 39 days in genotype JA 6 followed by 35 days in JA 10and 34 days in JA 4. The length of panicle was recorded longest from JA 1 (13.08 cm) and shortest in JA 2 (6.73 cm). Highest flower length was measured from JA 2 (26.39 mm) and lowest from JA 8 (8.31). Maximum number of branchlets per panicle was recorded from accessions like JA 1 (15.02) and it was least in JA 8 (7.39). Maximum number of flowers per branchlets was observed from JA 7 (12.07) followed by JA 4 (11.09). Number of stamens per flower varied between 58.04 and 67.07. The flower colour of all accessions was light yellow except JA 3(pale green). On the basis of this significant findings it can be conclude that the genotype JA 1 has most earliest flowering and biggest size flower from JA 2.
