        This study was conducted at the National Institute of Animal Science (NIAS) from 2010 to 2017 to develop a late-maturing variety with high productivity for cultivation in the southern region of South Korea. The new variety of Italian ryegrass, ‘IR901’, was a late-maturing variety, and its heading date was 22 May, 17 days later than that of the control variety ‘Kowinearly’. ‘IR901’ had a flag leaf width of 11.2 mm, flag leaf length of 31.8 cm, and plant length of 103 cm on its heading date. The combined average dry matter yield of ‘IR901’ in all three adaptability evaluation regions (Cheonan, Pyeongchang and Haenam) was 7,747 kg/ha, which was similar to that of the ‘Kowinearly’ variety (7,734 kg/ ha). However, the average dry matter yield over three years in Cheonan and Pyeongchang was 82% and 96%, respectively, compared to that of the control, which was most likely because of the poor cold tolerance of ‘IR901’. By contrast, in Haenam, in the southern region, the average dry matter yield of ‘IR901’ was 19% higher than that of the ‘Kowinearly’ variety. The proportions of crude protein (CP), total digestible nutrients (TDN), acid detergent fiber (ADF), and neutral detergent fiber (NDF) in ‘IR901’ were 8.6%, 59.7%, 36.9%, and 54.8%, respectively; the proportions were 0.2% lower, the same, the same, and 2.5% lower than those in the ‘Kowinearly’ variety. The determined in vitro dry matter digestibility (IVDMD) of ‘IR901’ was 72.2% higher than that of ‘Kowinearly’ (67.2). In general, of the two varieties, the forage quality of ‘IR901’ was marginally superior to that of ‘Kowinearly’.

        Most eukaryotic organisms, including plants, display specialized cellular and behavioral rhythms with a period of approximately 24 hours. The circadian clock generates this rhythm to convey daily or seasonal basis of temporal information, coordinating the proper phasing of many important cellular processes. Temperature compensation (TC) is one of the defining features of the clock mechanism. Under this function, the speed of the clock or period remains relatively constant over physiologically relevant temperatures, unlike the biochemical reactions. Thus, TC allows organisms to sustain their life ordinarily in various thermal environments by providing an accurate measure of the passage of time regardless of surrounding temperatures. Previously, Edward and his colleagues performed a quantitative trait loci (QTL) study to find TC related natural variations in the recombinant inbred line (RIL) population from two Arabidopsis ecotypes, which are adapted to different thermal environments; one parent is Cvi accession (Cvi) which originates from the warm climate, Cape Verde Island, and the other is Ler accession (Ler) from Northern Europe. For the two most significant QTLs, the core clock components in Arabidopsis clock, GIGANTEA (GI) and ZEITLUPE (ZTL) are proposed as strong candidates. Moreover, the amino acid substitution leading to GICvi and ZTLCvi (Ler to Cvi) are suggested to be the causal factors for the TC QTLs respectively. However, precise molecular mechanisms of these natural variations on TC are still not understood well. Here, we elucidate the molecular impact of the natural variation shaping GICvi and ZTLCvi on TC function. GICvi and ZTLCvi post-translationally regulate ZTL stability in antagonistic way, resulting in the opposite period/clock effects mediated by ZTL protein abundance. However, if both GICvi and ZTLCvi are present, they mutually balance their own effect on ZTL, which in turn supports TC capacity of Cvi especially at high temperatures. Considering the amino acid residues in GI and ZTL, where the natural variations arise, are highly conserved across many important crop species including rice, corn, cabbage and etc., this research will give valuable insights into the TC related thermal adaptive processes in Arabidopsis as well as those important crop plants.

        A clone bank that contained highly productive and superior genotypes of R. coreanus Miq. was assembled in 1998. The clone bank was composed of a collection of 227 clones from 15 regions in Korea. From the clone bank, 198 clones that regularly completed flowering and fruiting were used as official materials for superior tree breeding. To evaluate the flowering and fruiting, the length of the fruiting lateral (LF), the number of flowers per fruiting lateral (NFL) and the number of fruit per fruiting lateral (NFFL) were investigated. Fruits were harvested when they fully ripen and the fruit length (FL), fruit width (FW), the weight of fruit (WF) and soluble solids were measured. In 2001, 17 of the original 227 clones were identified as being the most superior, and these selected genotypes were tested for regional adaptability in four different regions in 2002. Finally, these advanced selections including "Jung-Keum 5" were evaluated for flowering, fruiting and fruit production characteristics from 2002 to 2005. The new cultivar, "Jung-Keum 5" has black fruit color and larger fruit size than the contrast clone that was shown mean value for the most characteristics. Selection effect of the new cultivar were shown 148.8% (NFL), 151.2% (NFFL), 125.2% (WF) and 160.4% (yield/individual; YI) superior in comparison with the contrast clone, respectively.
