Genetic Analysis of F 2 Population Derived from the Cross Between Perilla Frutescens var. Frutescens and var. Crispa

In this study, genetic analysis was conducted on the inheritance of qualitative traits, such as leaf color, flower color, seed size, and seed hardness, in the F2 population derived from the cross between var.frutescens and var.crispa.As determined by the separation pattern of each trait in the F2 population, F2 plants with a green color were more common than those with a purple color on the leaf surface, whereas F2 plants with a purple color were more common than those with a green color on the reverse side of the leaf.For flower color, more F2 plants were observed to have a white color.For seed size, more F2 plants were observed to have a seed size of above 2 mm, and for seed hardness, more F2 plants were observed to have characteristics of seed hardness.Our examination of the genetic separation ratios with respect to Mendel's law of genetics revealed that three traits, leaf color (surface and reverse side) and flower color, did not follow the separation ratio of 1:2:1, and the seed size did not follow the segregation ratio of 3:1, but seed hardness was found to follow the separation ratio of 3:1.The results of this study are expected to provide basic information to help understand the genetic segregation of leaf and seed characteristics in the F2 population derived from the cross between var.frutescens and var.crispa, and also to provide useful information for breeding studies to assist the development of varieties of Perilla crop.
