백진주'는 1991년 하계에 개화 후 수정된 양질다수성 품종인 일품벼 수정난을 26±1℃ 암조건에서 1 mM의 MNU 용액에 45분간 침지한 후 24시간 동안 수세하였다. 처리한 식물체를 온실에서 등숙시켜 종실을 수확하여 돌연변이 M1세대 697개체를 얻었다. 1992년 하계 온실에서 M2세대 15개체를 선발하여 1992/'93 동계 온실에서 M3 집단을 육성하였다. M4 세대부터는 포장에서 계통 선발법에 의해 주요 병해충 및 미질검정을 병행하여 다양한
Baegjinju' is a new japonica rice cultivar developed from 'Ilpumbyeo' mutation lines as N-methyl-N-nitrosourea (MNU) treatment on fertilized egg cell by the rice breeding team of National Crop Experiment Station, R.D.A in 2001. This variety has about 136 days of growth duration from transplanting to harvesting in central plain area of Korea. It has a good semi-elect plant type and resistance to lodging with strong culm. The number of panicles/hill of 'Baegjinju' is a more than that of 'Hwaseongbyeo', and milled rice of that shows dull and medium short grain. It has very low amylose content (9.1%) and similar gelatinization temperature and good palatability of cooked brown and milled rice compared with 'Hwaseongbyeo'. This rice variety has slow leaf senescence and considerably tolerance to viviparous germination during the ripening stage. 'Baegjinju' is susceptible to leaf blast, bacterial blight, virus diseases and insect pest. The yield performance of this cultivar in milled rice is about 5.18 MT/ha by ordinary season culture in local adaptability test for three years from 1999 to 2001. 'Baegjinju' is highly adaptable to central and southern plain areas of Korea.
