Abstract:
An experiment was carried out at the Research Field of Sher-e-Bangla Agricultural
University, Dhaka, Bangladesh with 10 wheat varieties, sown in RCBD with 3
replications during November 2018 to March 2019. The purpose of this field
experiment was to select the best varieties crossing for further research program.
Analysis of variance showed significant differences among the varieties for all the
traits. Days to maturity (0.84), plant height at maturity, (cm) (1.96), peduncle length
(cm) (2.37), number of spikelet per spike (5.65), number of grains per spike (1.05)
and grain yield per plant (g) (3.68) showed minimum difference between genotypic
and phenotypic variance. Biomass/plot (g) showed high heritability (65.54) coupled
with high genetic advance (370.17) and very high genetic advance (28.11) in
percentage of mean. Correlation revealed that grain yield per plant had positive
genotypic and phenotypic association with days to maturity (G = 0.996 and P =
0.832), number of productive tillers per plant (G = 0.444 and P = 0.336) and spike
length (cm) (G = 0.761 and P = 0.111). Path analysis revealed that days to maturity
(0.859), number of productive tillers per plant (0.078) and number of grains per spike
(0.217) had positive direct effect on grain yield.
