홍하철,정국현,원용재,안억근,현웅조,양창인,이상복,김명기,성열규 한국국제농업개발학회 2017 韓國國際農業開發學會誌 Vol.29 No.4
본 연구는 북한에서 개발된 벼 유전자원들을 중부지역에서 재배하여 주요 농업적 특성을 분석하여 북한지역 적응 벼 신품종개발 연구에 유용한 유전자원으로 활용하고자 실시한 결과는 다음과 같다. 1. 수집된 북한 벼 유전자원은 수원과 철원에서 7월 10일부터 8월 10일까지 분포하는 조생 및 준조생 자원이었다. 2. 북한 벼 유전자원들의 출수기는 두 지역 간에 유의한 차가 인정되었으며, 조생자원에서 철원이 수원보다 출수가 빨라지는 경향이었으나, 준조생 자원은 반대로 철원에서 출수가 늦어지는 경향이었다. 3. 간장, 수장, 주당수수, 수당립수 및 등숙률은 두 지역 간에 고도의 유의한 차가 인정되었으며, 간장과 수장은 수원에서 철원보다 더 길었으며, 주당수수 및 수당립수는 수원이 많았고, 등숙률은 수원이 철원보다 높았다. 4. 현미천립중은 지역 간 유의성이 인정되지 않았으나, 지역 x 품종의 교호작용은 고도의 유의차가 인정되었으며, 정현비율과 ha당 백미수량은 지역간 고도의 유의성이 인정되었으며, 정현비율은 철원이 높았고, ha당 백미수량은 수원이 많았다. 5. 북한 벼 유전자원들은 흰잎마름병 K2, K3, K3a 균주에 약한 특성을 보였고, 도열병밭못자리검정에서는 중이상의 저항성을 보였다. This study was carried out in Suwon-central plain, and Cheorwon, mid-northern plain of Korea to evaluate agricultural characteristics including heading date and yield component for NorthKorean rice germplasm. The difference between two regions of the heading dates of germplasm was recognized the significance and early matured group growing in Cheorwon tended to flower earlier thanthat of Suwon while mid-early matured group showed an opposite result. The other agricultural characteristics such as culm length, panicle length, number of panicles per hill, number of grains per panicle,and ripened grain ratio, of the two regions of all traits were highly significant, especially culm length and panicle length in Suwon were longer than those were growing in Cheorwon. Number of panicles per hilland number of grains per panicle in Suwon were more than that were growing in Cheorwon, and ripened grain ratio in Suwon was higher than that of Cheorwon. The another difference between both theregions, of 1000-grain weight was not significant while the effect of interaction between the regions and variety was highly significant. Whereas brown/rough rice ratio and milled rice yield were highly significant;higher in Cheorwon for brown/rough rice ratio and in Suwon of milled rice yield. Additionally, the results concluded that, the North Korean rice germplasm showed susceptible response to bacterial leafblight(BLB) races such as K2. K3, and K3a but more than mid-range resistant response to rice blast.

북한 벼 품종의 평야지와 고랭지간 수량 및 미질 특성 비교
金永斗,盧泰煥,李載吉,梁報甲,李善龍 韓國作物學會 1996 한국작물학회지 Vol.41 No.5
본 연구는 북한에서 육성된 벼 품종을 남부산간 고냉지인 운봉과 남부 평야지인 익산에서 재배한 후 이들에 대한 수량성 및 쌀의 품질 관련 이화학적 특성을 분석하여 육종연구의 기초자료로 활용하고자 실시하였다. 1. 북한 벼 품종의 주당 수수 및 천립중은 지역간 유의성이 없었으나 수당 입수와 등숙율 및 수량은 두 지역간에 유의한 차이가 인정되었고, 수량에 대한 수량 구성요소별 기여도는 익산에서는 등숙율이 가장 컸고 운봉에서는 천립중이 가장 컸다. 2. 단백질, 아밀로스함량, 알칼리붕괴도 및 Mg/K 당량비는 지역보다는 품종간 변이가 컸으며 Mg 및 K함량은 지역, 품종간 및 품종 지역간(V L)교호작용 변이에서 모두 고도의 유의성이 인정되었다. 3. 아밀로그램 특성인 호화 개시온도, 최고점도, 강하점도, 취반점도 및 응집점도는 지역, 품종간 및 V L 교호작용 변이에서 모두 고도의 유의성이 인정되었다. 4. 밥의 텍스쳐 특성인 경도, 응집성 및 탄력성은 지역간에는 유의성이 없었으나 품종 및 V L 교호작용 변이는 뚜렷하였으며 부착성, 점탄성 및 저작성은 지역, 품종간 및 V L교호작용 변이에서 모두 고도의 유의성이 인정되었다. This experiment was carried out to obtain the basic informations on yield performance and physicochemical quality properties of North Korean rices at southern high altitude area, Unbong and southeren plain area, Iksan. North Korean cultivars showed significant difference in number of spikelets per panicle, percentage of ripened grain and yield between two locations, but not significant in number of panicle per hill and l000-grain weight. The highest contribution to grain yield was the percentage of ripened grain and l000-grain weight at Iksan and Unbong, respectively, The protein, amylose content, alkali digestion value and Mg/K ratio showed larger variation in varieties than that in the locations cultivated. Mg and K revealed highly significant variations in locations, varieties and variety ~times location (V~times L) interaction. The amylogram characteristics such as initial pasting temperature, peak, breakdown, setback and consistency viscosities showed highly significant variation in locations, varieties and V~times L interaction. The physical characteristics of cooked rice such as adhesiveness, gumniness and chewiness also showed highly significant variations in locations, varieties and V~times L interaction.

O-Young Jeong,Jeom-Ho Lee,Ha-Cheol Hong,Eung-Gi Jeong,Jin-Soo Paek,Chang-Ihn Yang,Yong-Hee Jeon,Myeong-Ki Kim,Kyu-Seong Lee,Sae-Jun Yang,Young-Tae Lee 韓國作物學會 2008 한국작물학회지 Vol.53 No.1
This experiment was carried out to evaluate the agronomic stability of North Korean rice varieties using the statistical model developed by Grafius, Finlay, and Ever hart. The lowest yearly variation based on coefficients of variation was found in Hannam 29 for number of panicles per hill, in Sijoong 9 for number of grains per panicle, in Pyeongyang 3 for ripened grain ratio, in Sijoong 16 for 1,000 grain weight, and in Yeomju 1 for grain yield. By Grafius's model, Pyeongbook 3, Weonsan 66 in early maturing groups and Seohaechalbyeo in medium maturing groups show stable for 3 years. Weonsan 66 in early maturing groups and Seohaechalbyeo in medium maturing groups were found to be highly stable as analyzed by both Finlay and Wilkinson's model and Everhart & Russell's model. With reference to three models, Weonsan 66 was highly stable for 3 years with showing more yield than Odaebyeo in early maturing groups while Seohaechalbyeo was highly stable for 3 years with showing high yield than Hwaseongbyeo in medium maturing groups above 5~;t~;ha-1 of milled rice respectively.
