A ‘Hayanchal95’, a new waxy corn hybrid, is a single cross hybrid developed by the maize breeding team at the National Institute of Crop Science (NICS), Rural Development Administration(RDA) in 2011. This hybrid was made by crossing between seed parent KW44 and pollen parent KW35. Days to silking of Hayanchal95 was three days earlier than Ilmichal, a check hybrid. Ear length and diameter of Hayanchal95 were 18.3 cm and 4.1 cm, respectively. The ratio of kernel set length to ear length was 90% and lower than Ilmichal. Its quality characteristics like amylopectin content, hardness of kernels, and value of sensory evaluation were not significantly different from Ilmichal except grain length. Resistance to corn borer and lodging tolerance of Hayanchal95 were better than Ilmichal. The number of fresh ears was similar to those of Ilmichal and weight of fresh ears was lower than Ilmichal in regional yield trials (RYT) from 2009 to 2011. Although flowering time of its parent lines was good match during crossing between the seed and pollen parents, seed production was low. It is adaptable to the whole country. Plant variety protection right of ‘Hayanchal95’ was registered in July 2014, and its grant number is 5110.

A single cross hybrid, ‘Godangok’, is a yellow sweet corn developed by the maize breeding team at the National Institute of Crop Science (NICS), Rural Development Administration (RDA) in 2011. This hybrid was produced by crossing between KSE5 and KSE19. KSE5 is a seed parent and KSE19 is a pollen parent of Godangok. Days to silking of Godangok was 3 days later than Danok 3, a check hybrid. Ear length and diameter of Godangok were 17.6 cm and 4.4 cm, respectively. The ratio of kernel set length to ear length was 87.1%. These characteristics of ear were similar to those of the check hybrid. However, the Degree Brix was 24.3 °Bx, higher than the check hybrid, 14.1 °Bx. Lodging tolerance of Godangok was better than the check hybrid. The number and weight of fresh ear of Godangok were similar to those of the check hybrid in regional yield trials (RYT) from 2009 to 2011. Seed production of this hybrid is good due to good match between the seed and pollen parent. It is adaptable to the whole country. Plant variety protection right of ‘Godangok’ was registered in July 2014, and its grant number is 5094.

A new naked oat (Avena sativa L.) cultivar ‘Suyang’ was developed by National Institute of Crop Science, RDA in 2010. It was derived from the cross between ‘Sikyonggwiri’ and ‘Gwiri23’. Subsequent generations were handled in a bulk method and pedigree selection program, and ‘SO96025-B-303-44-2-4’ was selected for agronomic appearance in 2002. The line showed both high yield and good husking rate of seed in the Yield Trial tested at Suwon in 2003 to 2004, being designated as ‘Gwiri56’. The ‘Gwiri56’ was subsequently evaluated for winter hardiness, earliness, and yield in four locations, Gimje, Iksan, Jeongeup and Jinju from 2005 to 2010 and was released as the name of ‘Suyang’. ‘Suyang’ had 11 days earlier heading date and 6 days earlier maturing time than the check cultivar ‘Seonyang’ in field condition. The ‘Suyang’ had 23.7 cm of spike length, 568 spikes per m², 73 grains per spike, 29.2 g of 1,000-grain weight, and 646 g of test weight. ‘Suyang’ showed better winter hardiness than that of the check cultivar ‘Seonyang’, and similar seed quality to the check cultivar in respect to crude protein (11.3%) and β-glucan content (4.7%). However, it showed higher husking rate than that of check cultivar. The grain yield of ‘Suyang’ in the regional yield trial for 4 years was averaged 4.35 MT ha^-1, which was 29% higher than that of the check cultivar ‘Seonyang’. ‘Suyang’ is recommended for fall sowing cropping only in the south area where daily minimum mean temperatures are averaged higher than -4°C in January.
