Abstract
The research was carried out in Babil Governorate / the project area, which is 42 km from the
center of Babil Governorate. The cultivation was carried out in 4/2/2020 and the harvest was
done on 9/5/2020. For the purpose of studying the performance evaluation of three potato
genotypes (HERMOSA, SIFRA and ALVERSTONE) under the influence of bio-fertilizers
(Mycorrhizal fungi (MY) and Azotobacter (AZ)) and organic (ITALPOLLINA chickens) at
eight levels (0, I, MY, AZ, MY* I, AZ*I, MY+AZ and (MY+AZ)*I) using a randomized
complete block design (RCBD) with three replications, and a total of (72) experimental units
divided into eight environments to perform genetic calculations. The results are as follows:
1- High values of genetic variance compared to environmental variance for all traits. The
characteristic of the leaf area of the plant (cm2. Plant-1) gave the highest genetic, environmental
and phenotypic variance for the two seasons and for all eight environments.
2- The values of the genetic variation coefficients (G.C.V.) and phenotypic (P.C.V.) range from
medium to high for most traits for all eight environments, due to the higher values of genetic
and phenotypic deviation for these traits than the average trait, except for some traits where
they were low. This is because the variance is small for these characteristics, which led to the
lack of deviation, and therefore the coefficient of variation was of a low value.
3- High percentage of heritability in the broad sense (H2BS%) for all traits and all
environments. The high values of heritability in the broad sense of the above traits are attributed
to the high values of genetic variance compared to environmental variance, and this indicates
that genetic structures transfer their good traits from one generation to another at very high
rates with little impact on the environment.
