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.
