Description Studies on variability, correlation, path coefficients and principal component analysis
were studied on chilli, tomato and potato. The data were collected from AICRP on Vegetable
and AICRP on potato.
Majority of the traits exhibited high PCV and GCV indicating wide range of variation
in respect of the characters studied for all the crops (i.e., chilli, tomato and potato).
Similarly, high heritability coupled with high genetic advance over the mean was registered
for most of the characters in all the crops.
Highly significant and negative correlation were noticed between yield with all the
characters except dry fruit yield per plant in chilli. In case of tomato, the yield had highly
significant and positive correlation with number of primary and secondary branches, number
of locules, number of clusters per plant and total fruit weight per plant at genotypic level.
Germination percentage, plant height, number of stems per plant and number of tuber per
plant were significantly and positively correlated with tuber yield in potato.
Path coefficient analysis revealed that plant height and fruit length were found to be
the most yield predicting factors. In case of tomato and potato, number of clusters per plant,
number of secondary branches and average tuber weight, number of tubers per plant,
respectively were observed.
Principal component analysis for chilli, tomato and potato yield revealed that the first
three principal components (PC) absorbed more than 90 per cent of the variation explained by
explanatory variables.
The highest score coefficient was registered for dry fruit per plot yield (chilli), plant
height (tomato and potato) in the first PC and number of fruits per plant (chilli and tomato),
number of tubers per plant (potato) in the second PC.
The sphericity test was confirmed that all the principal components were differing
with each other for chilli, tomato and potato crops.
