들깨 수집종의 생육 및 수량관련 형질 비교

This study was conducted to measure the major agronomic characteristics of 85 local varieties of perilla at Chungbuk Agricultural Research and Extension Services in 2001. Perilla accessions examined were classified into three maturity groups, i.e, early, medium, and late maturity group of 19 (23%), 57 (67%), and 9 (10%) accessions, respectively. The early and late maturity groups mainly consisted of collections from middle-northern area and southern area, respectively, while the medium group consisted of accessions from all over the country. Average 1, 000-seed weight (TSW) was 2.7 g. TSW of the collection from Hamyang was the greatest a 3.9 g, while the TSW of Pyungchang collection was the smallest as 1.7 g, and most of collections produced medium and small seeds. Perilla accessions with greate 1, 000-seed weight seemed to be belonged to the late maturity group. Seed coat colors of perilla accessions were dark brown (30%), brown (55%) and gray brown (6%), respectively. Among seed coat colors, brown color consisted of 91%. Stem height, the number of nodes, branches, flower clusters, and capsules per flower cluster, and the length of flower cluster were positively correlated occ, while these characteristics were negatively correlated with the number of capsules per flower cluster and 1, 000-seed weight. These results allowed us to select 5 perilla collections, containing 1 collection with gray white seed color, and 4 collections over 2.5g 1000 seed weight, as parental lines in the breeding program.
