Variation in morphological descriptors among different populations of Grewia optiva Drummond (Beul) in Himachal Pradesh

Abstract

Fifteen Populations of superior plus trees (20-30cm diameter) of Grewia optiva Drummond (Beul) have been selected for study in three districts viz; Kangra, Hamirpur, and Mandi of Himachal Pradesh. To study the variation in morphological descriptors among different populations, all the qualitative, quantitative and pseudo qualitative characteristics were recorded. On the basis of overall scoring index of useful desired traits, the population site (Bharnoi-MN5) has proved the superior population. Whereas the population site; (Balt-MN4), and (Old Kangra-KR3) were statistically at par and both populations are ranked at number 2. Hence, these populations are significantly proved the best sources, on the basis of natural phenotypically observations and scoring index on each individual traits for selection and screening of superior individuals within the populations, so as to get improved genetic gain and establishment of gene bank of superior families and best genotypes of the families.
