Chlorophyll and protein content variability in Giloy [Tinospora cordifolia (Willd) Miers] under mid-hill conditions of Himachal Pradesh, India

A study of chlorophyll and protein content variability in giloy under mid-hill conditions of Himachal Pradesh was carried out during 2008–2009. Survey was conducted and stem cuttings from base region of giloy were collected from twelve different altitudes of District Kangra (Himachal Pradesh). The pot trial was carried out in the main campus of Himachal Pradesh Krishi Vishvavidyalaya, Palampur by vegetative propagation through stem cuttings of the surveyed collections in the month of May-2008 for first seasonal growth. Significant variation was observed in chlorophyll content but variation was non-significant for protein content. Chlorophyll content of the plant varied from 14.51 (collection-4) to 23.03 (collection-9) ?g/g. Protein content ranging from 9.97 (collection-4) to 14.04 (collection-11) per cent. Conclusively, based on overall performance collection-9, collection-11 and collection-8 emerged to be the best collections.
