Hybridization and assessment of new genotypes of Iris germanica

This study aimed to evaluate 43 promising genotypes and 7 parents of Iris germanica, in terms of genetic divergence between genotypes and to estimate genetic parameters by using a morphological variation to determine their potential for genetic improvement of Iris germanica. ‘PRC10’ and ‘OPRC11’ were shown to be promising genotypes, having the highest flower size compared to other genotypes and parents, hence are suggested for direct commercial cultivation as well as utilization in the breeding programs for generating new genotypes.
The genotype ‘OPRC8’ was the most significantly different in crown diameter, the diameter of floral branches, and flower peduncle diameter.
Relatively high heritability values, in a broad sense, were found with 97% for plant height, floral fall width and length, flower size, and leaf width.
These characters may be applied as useful traits in breeding Iris germanica and for the selection of genotypes.
