Floral Biology and Breeding system of Tea [Camellia sinensis L.]: Implication on the Tea Breeding Programme (original) (raw)

Comprehensive knowledge in reproductive traits is a prerequisite in utilizing the existing germplasm effectively for crop improvement. A representative sample of germplasm accessions were used to study floral morphology, pollen biology and stigma receptivity in tea. The results revealed a wide qualitative and quantitative variability in floral morphology, including flower size, number and arrangement of corolla, characteristics of the pistil, pollen viability and germination and stigma receptivity. Four main categories were identified based on size of the flower. On the basis of anther dehiscence, accessions were categorized as early maturing, immediate or as late maturing. Significant differences were noted in percentage germination of pollen and pollen viability among the accessions. Presence of non-viable pollen was found to be characteristics to certain accessions. Stigma was receptive even in the stage of mature un-open flower buds. The present study being the first comprehensi...
