Current Institute Projects:

High Temperature and soil moisture deficit stresses in banana: Mechanism of high temperature tolerance and management of high temperature and soil moisture deficit stresses in banana(PI)
Biochemistry of banana fruit ripening and characterization of high value compounds of fruit and flower (Co-PI)
Functions of resistant starch and designer food development from banana flour (Co-PI)
Development of clump management technology for enhanced productivity in banana (Co-PI)

Current External Projects:

Component - 2: Bio fortification and evaluation of Indian banana with Iron constructs – DBT- QUT
Whole genome and transcriptome study to stress tolerant banana cultivars – DBT –NER
In vitro mass propagation of high value hill area banana – DBT –NER
Characterization of high value phyto-chemicals of anti-diabetic and immune-modulatory properties in NE banana varieties– DBT –NER
Network project on Transgenic in crops – Banana functional genomics (Sigatoka & Drought component) –ICAR- Network Project

Identified drought and salt tolerant banana genotypes and released a banana variety as ‘Kaveri Saba’ as drought and salt tolerant variety.
Physiological traits for drought tolerance has been identified for screening bananas in the field.
Identified critical phenological stages of banana for irrigation to avoid water deficit stress effect.
Technologies for alleviation of drought and salt stress injuries have been developed.
Technique to differentiate dessert and cooking bananas based on amylose content from un-ripened green banana fruit has been developed.
Technology to improve bunch development through post flowering growth regulator application on the bunch has been developed. This technique enhance the fruit filling and development which are desirable for marketing the produce.
Optimised the leaf number in popular bananas (cvs. Robusta, Karpuravalli, Ney Poovan, Saba, Poovan, Nendran at flowering for normal fruit development without affecting fruit quality. Keeping optimum number of leaves promotes light penetration to the lower leaves, reduces water loss through transpiration and reduces spread of leaf spot disease.
