Multivariate analysis of morphological characteristics in Iris germanica hybrids

This study aimed to evaluate the genetic difference between 43 F-1 hybrids and 8 parents, seven of Iris germanica and one of I. spuria and to estimate genetic parameters by using 10 descriptors and the morphological variation to determine their potential for genetic improvement. The mean comparisons showed that the Iris hybrids 10 and 11 had higher flower size than other Iris hybrids and the parental, a coveted trait that could be used in breeding programs, with the aim of increase sales. The Iris hybrid 8 showed the most significantly difference in crown diameter, flower branches diameter and flower peduncle diameter. The cluster of largely are could separation hybrids in terms of morphological characteristics. Irises a trait correlation with other traits makes possible indirect measurement. Relatively high heritability values, in broad sense, were found 97% for height plant, fall width and length, flower size and leaf width. These characters may be applied as useful traits in Iris breeding and for selection hybrids.
