Two split-hull mutants were induced a) by the treatment of chemical mutagen, N-methyl-N-nitrosourea (MNU), in the fertilized egg cells of Hwasunchal and b) in the progeny crossed between Stay-green and Indica-like mutant lines. This study was carried out

A new pink gerbera (Gerbera hybrida Hort.) cultivar ‘Pink Angel’ was developed from a cross between ‘Tamara’ and ‘Nevada’ followed by seedling and line selections at the Flower Breeding Research Institute, Gyeongnam Agricultural Research and Extension Ser

A new red gerbera (Gerbera hybrida Hort.) cultivar ‘Honeymoon’ was developed from a cross between ‘Beauty’ and ‘Sardana’ at the Flower Breeding Research Institute, Gyeongnam Agricultural Research and Extension Services (ARES) in 1998. Characteristic trial

In order to measure an antifreezing tolerance, antifreeze proteins accumulated upon cold acclimation in apoplast were analyzed. As Dongborilho were cold-acclimated for 3 to 74 days there was an abrupt increase in apoplastic proteins up to 30 days and then decrease to the similar levels. Among the known antifreeze proteins, CLP produced in E. coli. and TLP purified from apoplast were used to generate antisera that allow to measure and localize the proteins in leaves of barley. The CLP of 27.7 kDa and TLPs of 6, 26, 27, 30, and 31 kDa were increased in their amounts in apoplast as cold treatment being longer. There was a correlation among the amounts of those proteins accumulated in apoplast and freezing tolerance as shown in field and ion leakage tests for five cultivars. The deposit of CLP was localized in the marginal area and the area adjacent to leaf vescular bundle cells in an increasing manner according to duration of cold acclimation but no variation was observed in terms of it's distribution. Based on the close correlation between levels of antifreeze proteins and degrees of freezing tolerance, the immunological methods was to develop to estimate a freezing tolerance in barley

This study was carried out to understand the genetic pattern of self-sterility, using a self-fertile variety Cheongyangnative 1 and nine self-sterile cultivars in cultivated boxthorn (Lycium chinense Mill., 2n=24). The inheritance of self-fertility (SF)wa

Regional Adaptability Test (RAT) was conducted to select promising breeding lines of rice for cultivation in specif ic regions. Analysis of genotype (G) and genotype by environment (G×E) interaction observed in RAT was carried out to test their adaptabili
