A Waxy Black Giant Embryo Earley Maturing Rice Variety ‘Nunkeunheugchal’

Abstract

The local adaptability test of Milyang263 was carried out at four locations from 2010 to 2012 and it was named as Nunkeunheugchal. This variety is a early maturity cultivar. It has 65 cm in culm length and 72 spikelets per panicle, and 1,000 grain-weight of brown rice is 17.8 g which is less than that of Josaengheugchal. This variety is resistant to leaf blast, but susceptible to bacterial blight, neck blast, virus disease and insect pest. The yield potential of Nunkeunheugchal was about 3.54 MT/ha as brown rice at ordinary fertilizer level in local adaptability test for three years. Nunkeunheugchal possesses benefits to rice consumers because of high amounts of GABA, anthocyanin, calcium and iron. This variety would be adaptable to the paddy field of middle and southern plain region of Korea.

Effect of GABA Extract of Black Sticky Rice with Giant Embryo on Alcohol‐Related Indices After Acute Alcohol Intake in Social Drinkers

“…Meanwhile, black sticky rice with giant embryo (BSRGE; “Nunkeunheugchal”), which is known to contain higher level of GABA, was developed by the rice breeding team of National Institute of Crop Science of Rural Development Administration in 2012. Embryonal weight of “Nunkeunheugchal” is 1.46 mg, and it is 3 times heavier than general rice “Josaengheugchal.” Therefore, GABA content known to contain mainly in embryo is 34 mg/100 g, and it is 7 times more than “Josaengheugchal.” GABA content of germinated brown rice of “Nunkeunheugchal” is 88 mg/100 g, and it is 1.7 times more than “Josaengheugchal” (Table ; Park et al., ). An animal testing with BSRGE indicated a change of alcohol intake.…”

The Effect of Oral Administration of Black Sticky Rice with Giant Embryo on Brain GABA Concentrations

“…The embryonal weight of “Nunkeunheugchal” is 1.46 mg. It is 3 times heavier than the general rice “Josaengheugchal.” The embryo contains a GABA concentration of 34 mg/100 g, which is 7 times higher than in “Josaengheugchal.” The GABA content of the germinated rice in “Nunkeunheugchal” is 88 mg/100 g, which is 1.7 times higher than that of “Josaengheugchal” [10] (Table 1). Investigations suggest an association between alcohol intake, alcohol-related indices and effects of BSRGE.…”
