Abstract | Seeded variety of zoysiagrass has not been bred yet in Korea. Development of seeded zoysiagrass cultivar will be very important for the growth of turfgrass industry internationally as well as domestically. This research was conducted to investigate seed yield and germinability of 102 collected native zoysiagrass ecotypes in South Korea. Two hundred and seventy seven ecotypes were collected from various locations including coastal and mountain areas, while 102 morphologically distinct and seed producing ecotypes were selected and planted in $1m{\times}1m$ maintenance plots. Seed yield ranged from 0.1 to $32.2g\;m^{-2}$. Highest yielding line was a medium leaf type zoysiagrass of Z6011 with $32.2g\;m^{-2}$. Most collected lines showed seed germination rates of below 50%. However, Z2095 showed highest germination rate of 78%. Considering germination rate and seed yield, collected lines of Z6011, Z 6015, Z1075, ZN1008, and Z1084, which were mostly medium leaf type and Z. japonica types, showed reasonably high potential to be used as breeding lines for high yield seed varieties of zoysiagrass. 국내에 종자형 품종 개발은 아직 전무한 상태이다. 한국잔디의 종자형 품종 개발은 국내외 잔디산업 발전을 위해서도 매우 중요한 일이다. 한국잔디 자생지인 국내 동,서, 남해안과 내륙지방에서 277 생태형을 수집 하였고, 이중에서 종자를 맺는 102개 수집계통에 대한 종자 수확량과 발아율을 조사하고자 본 연구를 수행하였다. 종자 수확량은 $0.1{\sim}32.2g\;m^{-2}$의 범위를 보였다. 수확량이 가장 많은 계통은 중엽형인 Z6011로 $32.2g\;m^{-2}$로 나타났다. 수집계통의 발아율은 대부분이 50%이하로 낮게 조사되었다. 발아율이 가장 높은 계통은 78%를 보인 Z2095로 조사되었다. 종자수확량이 높으면서, 발아율이 높은 계통으로는 Z6011, Z6015, Z1075, ZN1008, Z1084 등을 선발하였으며, 대부분 중엽형계통과 Z. japonica 계통이었다. 상기 선발 계통들은 향후 다수확 종자형 품종육성을 위한 유용한 유전자원으로 활용될 수 있을 것으로 생각된다. |
