'검구슬'은 국립식량과학원 남부작물부에서 2011년도에 육성한 검정색 종피의 팥 품종으로 1998년에 '칠보팥'을 모본으로 하고 SA8412-3-1-4-3-3-2-3을 부본으로 인공교배하여 계통육종법으로 선발한 계통으로 계통명은 '밀양 10호'이다. '검구슬'은 중간신육형으로 잎은 원형으로 크고 줄기는 녹색이며 협은 황갈색이다. '검구슬'의 성숙기는 9월 28일로 '충주팥'에 비해 2일 빠르고 개화기는 1일 빠르다. 경장은 56 cm로서 '충주팥'보다 짧고 개체당 협당립수는 비슷하다. 100립중은 12.2 g으로 충주팥보다 작은 중대립종이며, ha당 평균수량은 2.01 MT/ha으로 충주팥과 비슷하였다. 검구슬은 내도복성이 충주팥에 비해 매우 강하며 내병성은 비슷하고 수확종자의 항산화 성분함량이 높은 것으로 나타났다.

Adzuki beans have gained popularity in recent years due to their health benefits. Breeding of Adzuki beans is less favorable than with other legumes due to low genetic diversity. This study aimed to evaluate the genetic diversity of 252 adzuki bean germplasms from China, Japan, and Korea using 18 agro-morphological parameters and comparing their performance to three prominent Korean cultivars: Geomguseul, Arari, and Chungjupat. Leaf shape, pod color, and seed coat color were among the qualitative traits that showed wide variations. The quantitative variables also showed wide variations among adzuki bean germplasms. Although there was no significant difference (p < 0.05), the average rate of germination declined in the order of Korean (91.44%) > Chinese (91.31%) > Japanese (87.47%) adzuki beans. Chinese adzuki beans needed fewer days to flower (DF, 58.22 days) and days to mature (DM, 107.13 days), which varied significantly compared to the Korean and Japanese adzuki beans (p < 0.05). The average number of pods per plant (PPP) and one-hundred seeds weight (HSW) were higher in Japanese adzuki beans compared to the Korean and Chinese adzuki beans although the variation of each was not significant. Almost 29.76% of the accessions had early-blooming flowers, 3.97% were premature, 21.43% produced more PPP, and 3.97% yielded more SPP compared to control cultivars. Results of hierarchical cluster and principal component analyses revealed three clusters with significant variation in all quantitative variables except for RG (p < 0.05). The key factors in multivariate analyses were DF, DM, and HSW. Our study investigated the genetic diversity of adzuki bean accessions and identified ten early maturing and ten high PPP-yielding accessions. Our findings would help farmers and breeders to select the top-performing accessions that can provide them with various options.
