Growth characteristics and cross affinity among collected perilla-related genus and species

Major growth characters and intergenic or inter specific cross affinity of collected perilla-related genus and species germplasms such as Perilla frutescens var. japonica Hara, Perilla frutescens var. acuta Kudo, Perilla frutescens var. crispa Decaisne, Perilla frutescens var. Kudo for viridis Mak, Mosla punctulata Nak, Mosla japonica Max and Mosla dianthera Max were investigated to obtain the basic informations on varietal improvement in Perilla. The flowering date and plant height of perilla germplasms were 10 days later and 38㎝ longer than those of mosla germplasms. The yield and yield related characters such as panicle length, number of pods per panicle and 1000 grain weight of perilla germplasms were more and longer than those of mosla germplasms. Pod setting by intergenic and interspecific hybridization of collected perilla-related germplasms was found out in all crosses, howevar, seed setting was not found out intergenic hybridizations such as crosses between Perilla frutescens var. japonica Hara with Mosla punctulata Nak and Mosla japonica Max. The interspecific F₁ seed between collected perilla-related germplasms revealed the maternal-inherited characteristic in 1000-grain weight and seed coat colour.
