Abstract:
Ten genotypes of garlic (Allium sativum L.) were evaluated to study the evaluation of
genotypes at Sher-e-Bangla Agricultural University farm, Dhaka during November 2017
to March 2018. In this experiment ten garlic genotypes were used as experimental
materials. The experiment was laid out in Randomized Complete Block Design (RBCD)
with three replications. Mean performance, variability, genotypic and phenotypic
correlation coefficient and path analysis on different yield contributing characters and
yield of garlic genotypes were estimated. The highest bulb yield/plant in gram (13.57)
was recorded in the genotype of BARI Rosun-3, whereas the lowest bulb yield/plant in
gram (9.007) from the genotype BARI Rosun-2. Phenotypic coefficient of variation was
higher than the genotypic coefficient of variation for all the yield contributing traits.
High heritability coupled with high genetic advance in percent mean was observed for
bulb diameter. High heritability coupled with moderate genetic advance observes in
plant height, root length, total no. of leaves, bulb length, and yield per plant. In
correlation study, yield per plant positively and significantly correlated with root length
(0.388* & 0.367*) and bulb diameter (0.474** & 0.467**) at both genotypic and
phenotypic levels respectively. Path coefficient analysis revealed that positive direct
effects on yield per plant were obtained by root length (0.168), leaf breath (0.131), bulb
length (0.189) and bulb diameter (0.244).
