Evaluation of genetic variability, heritability and genetic advance for seed yield in oilseed camelina [Camelina sativa (L.) Crantz.]

Om Prakash, Ankur Agarwal and Madhu Bala


Camelina, a short gestation biofuel crop, has proved its potential as source of renewable biofuel worldwide. Introduction
of this crop to India is very recent. Twenty genotypes/lines including selective F1 crosses were evaluated in the present
study for genetic variability, heritability and genetic advance. High amount of inherent variability (genotypic coefficient
of variation) was exhibited by seed yield per plant (36.54), number of seeds per pod (21.00) and number of pods
per plant (12.17). Variability observed among the genotypes pointed out that there is large scope for selection of
promising material for the economically important traits such as plant height, number of branches per plant. The
characters studied in the present investigation expressed low to high heritability estimates ranging from 31.12% (number
of branches per plant) to 85.21% (Days to 50% flowering). Genetic advance was recorded high (>20%) for seed yield per
plant (46.57) and number of seeds per pod (28.43) whereas low genetic advance (<20%) was recorded for all other
characters. High heritability coupled with high genetic advance was recorded for number of seed yield per plant, and
number of seeds/pod indicating that these characters seems to be more heritable and can be improved by selection.
