Airborne particulate matter (PM) become a serious threat to climate, environment, and public health. To reduce PM concentration in the air, phytoremediation could be alternative and cost-efficient strategy. PM could absorbed into plants through foliar organ by 4 steps, absorption to leaf surface, translocation into leaf cell, dispersion into entire plant, and accumulation into specific plant organs. Thus, the phytoremediation by plant could be achieved through the first step, absorption to leaf surface, and this could be mediated by various factors, such as leaf surface characteristic, relative humidity, PM concentration in the air, etc. Soybean [Glycine max (L.) Merr] serve as one of the most valuable crop in the word and grow in around 127 million hectares worldwide. When typical varieties, which absorb PM more efficiently, are grown, phytoremediation could be achieved by the crop plant and contribute to reduce PM concentration in the air. In this study, temporal change of PM concentration by various soybean varieties in glass test chamber to investigate the PM absorption efficiency differences. Total 10 soybean varieties were test and their absorption rate. There are slight differences among soybean varieties, and this could be caused by the difference of leaf surface morphology. This result could provide the fundamental information for future soybean breeding program for phytoremediation as well as other crop plants.

Hyowon 2’, a new medium-late maturing glutinous rice variety with short clum and lodging tolerance was developed by the rice breeding team of Pusan National University in 2013. This cultivar was derived from a cross between Junam’ as a short clum source and ‘Donna’ with a good glutinous properties. During selected by the pedigree breeding method, until F8 generation. As a result, a promising line, JS22-3-24-1-6-2-1-1-1, was advanced and designated as the name of ‘SP 105’ in 2012. This variety headed on Aug. 22 is 9 days later than ‘Dongjinchal’ in middle plane. The Culm length and panicle length of this variety was 65.6 cm and 22.5 cm, respectively. This variety has about 14.4 tillers per hill and 113 spikelet numbers per panicle. The ratio of ripened grain is about 93.0% and 1000-grain weight was 18.4 g in brown rice. This variety has higher α-tocotrienol content compared to that of ‘Hwasunchal’. The yield performance of brown rice was 4.81 MT/ha in local adaptability test.

‘Hyowon 4’, a new medium maturing glutinous rice variety was developed by the rice breeding team of Pusan National University in 2013. This cultivar was derived from a cross between ‘Boseokchal’ and ‘Donna’ with good glutinous property. During F3~F8 generation, breeding lines were selected by a pedigree breeding method. As a result, the promising line (JS23-4-39-14-5-1-1-1) with good glutinous property was advanced and designated as the name of ‘SP 106’ in 2012. This variety headed on Aug. 15, which is 2 days later than ‘Dongjinchal’ in middle plane. The culm length and panicle length of this variety was 82.4 cm and 21.1 cm, respectively. This variety has about 13.9 tillers per a hill and 100 spikelets per a panicle. The ratio of ripened grain is about 92.0% and 1000-grain weight was 20.9 g in brown rice. The yield performance was 5.03 MT/ha in local adaptability test.
