영문 초록

The rice cultivar ‘Baekokhyang,’ a high-quality late maturing aromatic rice developed by Chungcheongnam-do Agricultural Research and Extension Services, was developed to cope with rising temperatures due to global warming and the market demand for various rice cultivars. ‘Baekokhyang’ was derived from a cross between ‘Ungwang,’ a multi-disease-resistant early-maturing rice cultivar as the maternal parent, and ‘Okhyangheugchal,’ an aromatic black rice as the paternal parent. Subsequently, a pedigree breeding method was used and yield trials were conducted from 2017 to 2018, followed by local adaptability tests from 2018 to 2019. ‘Baekokhyang’ is a late-maturing rice cultivar with the heading date of August 25th, demonstrating a slower maturation tendency compared to other medium-maturing cultivars, and this trait enables it to be ripened at an appropriate temperature after the heading date. ‘Baekokhyang’ exhibited tolerance to lodging, indicating high cultivation stability and more grains per panicle than ‘Samgwang. ’ Yield of milled rice was approximately 6.42 MT/ha under normal fertilizer levels in the local adaptability tests, which was 0.38 MT/ha higher than that of ‘Samgwang’. Additionally, the weight of 1,000 brown grains was 26 g which was 4.4 g heavier than that of ‘Samgwang’. The width/length ratio was 1.97, indicating the characteristic of long grains.The new rice cultivar ‘Baekokhyang’ is expected to enhance the competitiveness of rice production in Chungnam Province by diversifying the rice market which is currently dominated by non-glutinous and short-grain rice (Registration No. 8608).
