큰느타리(새송이)버섯 "애린이5" 품종육성

Breeding of Pleurotus eryngii, "Aeryni 5"

고품질이면서 수확량이 많은 한국고유 새송이버섯 품종을 육종하기 위하여 육종모본 $24{\times}46$과 KNR2539를 단교배하여 생육소요일수(14.6일)과 수량(85.9g/850cc), 품질(7.2)을 기준으로 $6{\times}13$계통을 선발하였다. 선발된 계통을 애린이5라고 명명하고 대량재배로 큰느타리2호와 생육특성을 비교하였다. 병당수량은 애린이5가 82.2g으로 대조품종 67.0 g의 122.7% 수준이었다. 품질의 경우 애린이5는 7.7, 큰느타리2호는 6.3으로 나타났으며 수량과 품질은 통계적으로 유의성을 보였다. 갓의 명도에 있어서 애린이 5는 61.7로 대조품종의 58.3보다 높아서 밝은 색을 띄었다. 유성에 있어서는 URP2프라이머에서 큰느타리2호와 부모친 KNR2539와 다형성을 보였다.

To breed a new Korean Pleurotus eryngii cultivar with high quality and yield, single crosses between $24{\times}46$ and KNR2539 were performed, and a new cultivar, $6{\times}13$, was selected based on the days to harvest (14.6 days), quality (7.2), and yield (85.9 g/850 cc bottle). The strain was named Aeryni 5 and cultivated on a large scale at the mushroom farms to compare with Keuneutari 2ho. The yield of Aeryni 5 (82.2 g) was 122.7% of Keuneutari 2ho, and the quality of the new cultivar was 7.7 while reference cultivar was 6.3. The yield and quality of the two cultivars were statistically different. The lightness of the pileus of Aeryni 5 (61.7) was greater than that of Keuneutari 2ho by 3.4 points; thus, the pileus of Aeryni 5 looked brighter. PCR with URP2 was used to discriminate between Aeryni 5 and Kenneutari 2ho.
