Abstract:
The present research work was conducted to study the multivariate analysis of
chilli during the period from November 2015 to April 2016 in rabi season in the
experimental field of Sher-e-Bangla Agricultural University, Sher-e-Bangla
Nagar, Dhaka. In this experiment fifteen chilli genotypes were used as
experimental materials. The experiment was laid out in randomized complete
block design with three replications. Mean performance, variability, correlation
matrix, path analysis and genetic diversity analysis on different yield and yield
attributes of chilli genotypes was estimated and significant variation was observed
for different chilli genotypes. The highest days to 1st flowering (75.33) was found
in the genotype G10 (SRC10) and the lowest days (58.33) was found from the
genotype of G2 (Bogra Zhal Morich). The maximum number of fruits/plant
(55.22) was found in the genotype G7 (SRC07), while the minimum number of
fruits/plant (20.67) was recorded from the genotype of G15 (Dark Green Papper).
The highest yield/plant (178.73 g) was observed in the genotype G2 (Bogra Zhal
Morich), while the lowest yield/plant (32.70 g) was found from the genotype G6
(SRC04). Phenotypic coefficient of variation was higher than the genotypic
coefficient of variation for all the yield contributing traits and yield. In correlation
study, highly significant positive association was recorded for fruit weight per plot
of chilli genotypes with number of branches per plant, fruit length, single fruit
weight and fruit weight per plant. Path analysis revealed that number of branches
per plant, days to 50% fruiting, single fruit weight and fruit weight per plant had
positive direct effect on fruit weight per plot. Diversity analysis revealed that
cluster I had the maximum (8) chilli genotypes followed by cluster III and II
which had 4 genotypes and 3 genotypes respectively. Inter cluster distance was
maximum (11.862) between clusters I and II. Considering group distance and
other agronomic performance Bogra Zhal Morich, Bora Special Morich, SRC06,
SRC07, SR09 and SRC10 genotypes may be suggested for future hybridization
program.
