본 연구는 농촌진흥청 국립원예특작과학원 채소과에서 육성 중인 고추 34계통과 세계채소센터 육성 계통과 자원 12점 등 총 46점의 고추를 공시하여, 종자의 발아율, 수량 및 상품과율, 그리고 화분발아율을 조사하여 내서성이 강한 고추 자원을 선발하기 위하여 수행되었다. 1. 종자발아율 비교에서 여름종자는 가을종자 대비 상대적인 피해율은 4.3~100% 범위였고, H42(1.6%), H16(5.0%), H14(6.3%), H02(12.4%), H44(13.7%), H12(15.9%), H03 (17.6%), H17(23.4%) 순으로 대조 계통인 H37(26.2%)에 비해 피해율이 낮았다. 2. 고추 과실의 수량은 34.4~446.5g, 총 과실수는 2.0~134.3 개를 나타냈다. 상품과 비율에 있어서 75% 이상은 H22(95.0%), H16(89.1%), H37(88.4%), H40(86.4%), H6 (86.0), H27(83.7%), H04(83.6%), H03(82.6%), H08(81.1%), H44(81.4%), H02(80.0%), H45(79.1%), H17(78.7%), H19 (77.7%), H34(77.0%), H15(76.9%), H42(76.3%) 순으로 나타 났다. 3. 고온 처리에 의한 화분발아율의 피해율은 H06(59.5%), H14(74.4%), H44(85.3%), H03(90.2%)가 대조구인 H37 (94.7%)과 나머지 다른 고추에 비해 상대적으로 낮았다. 이상의 결과, 가을종자 대비 여름종자 종자발아율의 피해율, 수량 및 상품과율, 그리고 고온 처리에 의한 화분발아율 등을 고려하여, H03, H04, H06, H14, H17, H22, H44, H45 계 통을 내서성이 높은 자원으로 선발하였다.

This study was conducted to select heat tolerant pepper accessions in tropical regions. Fruit yield and pollen germination rate between heat stress and normal condition as well as germination rate between seeds harvested in summer and fall were compared using 46 pepper accessions including 34 from Rural Development Administration and 12 from World Vegetable Center. For seed germination rate, the relative injury rate of summer seed ranged between 4.3 to 100%. Among accessions, H42 (1.6%), H16 (5.0%), H14 (6.3%), H02 (12.4%), H44 (13.7%), H12 (15.9%), H03 (17.6%) and H17 (23.4%) showed lower injury rate in seed germination than H37 (26.2%) which is known for its heat tolerance. Fruit yield and number per plant were in the range of between 34.4 to 446.5g and 2.0 to 134.3 fruits, respectively. The marketable fruit ratio ranged between 41.0 to 95.0% and accessions producing marketable fruits more than 75% were H22 (95.0%), H16 (89.1%), H37 (88.4%), H40 (86.4%), H6 (86.0), H27 (83.7%), H04 (83.6%), H03 (82.6%), H08 (81.1%), H44 (81.4%), H02 (80.0%), H45 (79.1%), H17 (78.7%), H19 (77.7%), H34 (77.0%), H15 (76.9%), and H42 (76.3%). The relative injury rate of pollen germination in heat stress condition was low in H06 (59.5%), H14 (74.4%), H44 (85.3%) and H03 (90.2%) compared to a control, H37 (94.9%). Based on the results of seed germination, marketable fruit yield and pollen germination, H03, H04, H06, H14, H17, H22, H44, H45 were selected for heat tolerance in tropical climate.
