Genetic Varieties of the Obtained Hybrids From the Potato (Solanum tuberosum L.) Tuber Intersections in the Spring Using the Factor and Cluster Analysis

A completely randomized block design test with three replications was executed in Ardabil for 2 years to examine the genetic varieties of the obtained hybrids from the Solanum tuberosum tuber intersections in the spring using the factor and cluster analysis.

LK5 genotype obtained by the intersection of cultivar Kaiser♀ × Lusta♂ with a mean of 54.45 ton/ha had the maximum and genotype LS12 obtained by the intersection of cultivar Savalan ♀× Lusta♂ with a mean of 28.16 ton/ha had the minimum tuber yield. The first component justified 36.2, 19.29, and 13.87% of all data changes. The by-plot diagram of Savalan cultivar introduced genotypes of LK11, LK9, LK7, LK4, and LK2 (obtained by the intersection of Kaiser ♀ × Lusta ♂) and genotypes LS7, LS5, and LS2 (obtained by the intersection of Savalan ♀ × Lusta ♂) as the most desired cultivars, respectively. In addition, the first, second, and third factors were called an effective factor on the properties of the tuber, an effective factor on plant height, and an effective factor on yield, respectively. According to the obtained results from the detection function, 38 hybrids with 4 parents (no. 13, 27, 41, and 42) were put in 4 groups. The first cluster includes genotypes LK2, LK1, LS2, LS6, LK12, LK11, LK9, LK7, LK6, LK4, LK3, and Hermes. This cluster has the second rank between groups based on tuber yield. The second cluster including genotype LK5 caused by the intersection of Kaiser♀ × Lusta♂ had the first rank based on tuber yield, and a superior hybrid of this cluster in hybridization can be used to increase tuber yield.
