This work was carried out to evaluate the resistance of potato germplasm against late blight in Korea. Seven races ofPhytophthora infestans were detected from the main potato growing areas. Three races of pathogen were isolated from mono-crop-ping areas a
Low temperature germination is one ofthe major determinants for stable stand establishment in the direct seeding method in temperate regions. Quantitative trait loci (QTLs) controlling low temperature germiability (LTG) and awn were confirmed in BC1F1 usi
A near-isogenic line CR1815, containing three introgressed segments on chromosomes 1, 7 and 9 from 0. rufipogon into the Oryza saliva cultivar Milyang23 background was developed based on MAS (marker aided selection) and backcrossing. The introgressed segm
This study was conducted to investigate the effect on shortening spring barley cultivation into three generations a year under field and unheated (vinyl or glass) greenhouse conditions in Iksan, Korea. Two-rowed spring barley varieties, Jinyangbori and Do
This study was carried out to analyze the mineral contents including calcium in brown rice for the rice plants transformed with CAX1 gene. In the previous study the transgenic rice plants overexpressing the Arabidopsis Ca2+/H- antiporter CAX1 gene were de
This study was carried out for the improvement of germination rate by breaking seed dormancy in barley, In spring and fall planting, Post-harvest treatment of seeds such as air-dried (24 hours) or soaked in the 100 ppm gibberellin for 10 to 30 minutes imp
The experiment was conducted to improve the selection efficiency m the first generation through the analysis of variation pattems of major tuber characteristics when raising hybrid seedling using the different plug cell size. The correlations in related t
This study was carried out to investigate the cultural conditions for optimizing kernel greermess in order to obtain basicinformation for breeding and cultivation of green-kerneled rice varieties. Thirty-days-old seedlings of two green-kerneled varieties,
Agrobacterium-mediated genetic transformation of Brassica juncea cultivars has been extensively performed for the purpose of molecular breeding. B. juncea L. Czern var. Laciniata Makino, a vegetable crop also called kyona, can be transformed using its hyp
Two-spotted spider mite (Tetranychiis urticae K.) can cause severe yield losses in maize (Zea mays L.). Diallel crosses (28 F1) and generation mean analysis were analyzed to determine the type of resistance to mite. In diallel crosses, Mean square for GCA
Quantitative trait loci (QTLs) related to cold tolerance traits in rice were identified using 93 SSR markers and 175 recombinant inbred lines (RILs) derived from the intersubspecific cross between the indica cultivar, "Milyang23" and the japonica cultivar
