The segregating frequency distribution of stay-green score and days to ear leaf senescence(DELS) from silking generally had a simple bi-modal pattern irrespective of planting dates and the pattern of stay-green score shifted to higher level with later stages. The Hi39/KS75 had the longest DELS and it showed highest stay-green characteristics at 67 days after silking(DAS). The KS75 was considered a useful material in breeding of stay-green lines. The distribution patterns of F₂ progenies of Ga209/Hi39 and Ga209/KS75 had highly characterized as related to stay-green at 37 DAS, but that of characteristics shifted to lower levels at 52 DAS, and maintained up to 83 DAS. In the progenies of the three crosses, F₂ from Hi39/KS75 showed high from early days after silking in stay-green score, DELS and number of fresh leaf. It was possible to obtain higher stay-green lines than those of parents in the cross of Hi39/KS75.

High heterosis was expressed in the days from silking to ear leaf senescence(DELS) of F₁ and even in that of F₂ population with Hi39/KS75. In the number of fresh leaf, fresh leaf area and chlorophyll content, highly positive heterosis was observed in F₁ but negative heterosis in F₂ population except Hi39/KS75. Inbreeding depression in the number of fresh leaf, fresh leaf area and chlorophyll content appeared remarkably with the progress of growth especially from 37 to 52 days after silking(DAS) in April 23 planting, but Hi39/KS75 had low inbreeding depression in DELS compared to other two F₂ populations. Among the characters related to stay-green, the number of fresh leaf showed the highest heritability in the crosses with three inbreds Ga209, Hi39 and KS75. The other characters except the days to maturity also exhibited relatively high heritability. Hi39/KS75 showed very high heritability irrespective of planting dates. The stay-green score was found to be significantly correlated with the number of fresh leaf, fresh leaf area and chlorophyll content at the DAS 52. A multiple regression analysis with F₂ population revealed that the number of fresh leaf was much accountable for the variation in DELS and stay-green score, but less accountable in later growing stage.

Esterase 同位酵素, 蛋白質 및 形態的 特性에 의한 고구마 品種 分類
Deog Su Kim(金德洙),Sung Kun Oh(吳聖根),Moon Sup Chin(陣文燮),Jeom Ho Ryu(柳點鎬) 한국육종학회 1996 한국육종학회지 Vol.28 No.2
This study was conducted to utilize effectively similar varieties of sweet potato at the National Crops Experiment Station of Korea in 1994. Those were classified by esterase isozymes, proteins and some morphological characteristics. The results were as follows. The esterase isozymes in the leaves were similar in Kanto 95-1 and Kanto 95-2, Beniastma, Beniaka, Beniazuma and Benikomachi, Kintoki and Kintoki-2, Hongmi and Hongmi-2, High Starch and Hi-Starch. The esterase isozymes in the tuberous roots were similar in Beniastma and Beniaka, shiroshistma and Shiroshastma. The protein banding patterns in the tuberous roots were similar in Kanto and Kanto 95-1, Beniastma, Beniaka, Beniazuma and Benikomachi, Simon and Simon-2, High Starch and Hi-Starch. The morphological characteristics in the field were similar in Kanto 95 and Kanto 95-1, Beniastma, Beniaka, Beniazuma and Benikomachi, Simon and Simon-2, High Starch and Hi-Starch. Beniastma and Beniaka were appeared as the similar varieties because those had the same esterase isozymes in the leaves, tuberous roots and protein banding pattern in the tuberous roots, and some morphological characteristics in the field.

미국 중국 인도 ICRISAT에서 도입된 수수 유전자원의 생육특성과 종실수량성을 비교분석한 주요결과는 다음과 같다. 1. 미국과 중국에서 1987∼1988년 도입, 1989년 5월 18일 파종 시험한 전 공시계통의 평균 출수기는 7월 31일이었고 개화기는 8월 7일이었으며 가장 빠른 계통은 7월 30일, 가장 늦은 계통은 8월 17일이었다. 간장은 전체평균 121㎝이었고 최저 73㎝, 최고 272㎝ 공시계통간 차이가 매우 컸다. 이삭당 종실수량은 전체평균 49g이었고 10a당 5.5t/㏊ 이었으며 최고 79g(8t/㏊이상)이었다. 특히 세포질 응성불임계통 8050A는 백색종피 계통으로 1대잡종의 종자친으로 유망하였다. 2. 1992년 6월 15일 파종 시험한 8806-1과 FS25E는 한 이삭의 종실수량이 100g 이상으로 유망시되었고 FS-5는 80g 수준이었으며 50g 이상되는 계통도 13계통이나 되어 1대잡종의 화분친으로 유망하였다. 3. 1993년 미국에서 도입, 6월 9일 파종 시험한 세포질 응성불임계통과 임성회복계통들은 단간 내 도복성 계통으로 1대잡종 육성의 교배친으로 유망하였다. 특히 응성불임계통 AT×ARG-1은 종자친으로 이용하고 RT×430과 RT×2536은 화분친으로 이용할 가치가 높았다. 4. 1992년 6월 15일 파종 시험한 ICRISAT의 ICSR 89002, ICSR 89045, PYE-Ⅱ83, ICSR 162는 임성회복계통으로 한 이삭당 종실수량이 75∼81g으로 유망하였으며 1993년 6월 9일 파종한 ICSR 89059, ICSR 89071. PYE-Ⅱ3은 백색종피종이고 한 이삭의 종실수량이 60∼88g으로 화분친으로 유망시되었다. 5. ICRISAT의 1대잡종중에서 PHT-I 1037, PHT-Ⅱ3014, PHT-Ⅱ 3051, DPAHT 1003, DPAHT 1009, DPAHT 1018은 한 이삭당 종실수량이 100∼117g으로 11∼13t/㏊의 종실을 생산할 수 있었다. Grain sorghum hybrids have been known to be resistant to and tolerant of drought and black streaked dwarf virus, and outyield maize in some environments. A study was conducted to investigate and select elite parental lines and hybrids of grain sorghum introduced from the United States of America, China and ICRISAT in India. Elite cytoplasmic male sterile and restorer lines for grain sorghum hybrids were evaluated and selected to develop and release high-yielding superior cultivars and hybrids adapted to Korean environmental conditions. The restorer lines that were found to be promising were 8806-1, FS25E, FS5, RTx430, RTx2536, ICSR 89002, ICSR 89045 and PYE-II83. 8050A and AT×ARG-1 were found to be the best cytoplasmic genetic male sterile lines that adapted well to Korean environmental conditions. The hybrids, PHT-I 1037, PHT-II3014, PHT-II3051, DPAHT 1003, DPAHT 1009, DPAHT 1018 performed well in Suwon Korea.
