Lateral roots formed on mungbean sprouts should lower their quality. The study was carried out to clarify the effects of aeration periods (AP; 1, 2, 3, and 4 hours) and temperature (AT; 20, 30, and $40^{\circ}C$) after 5 hour seed imbibition into 50 ppm benzyladenopurine (BA) solution on growth and morphological characters of mungbean (cv. Keumseongnogdu, Owoolnogdu and Zhong Lu 1) sprouts. On the 6th day, the mungbean sprouts were sorted by 4 categories on the base of hypocotyl lengths; > 7cm, 4 to 7cm, < 4cm, and non-germination to calculate their composition rates, number of lateral roots, lengths of hypocotyl and root, diameters at middle and upper parts of hypocotyl, fraction fresh and dry weights were measured. AP more affected growth of the cultivars than AT showing little effect on them. In the composition rate of the above 4 categories, cv. Zhong Lu 1 had the highest rate in longer than 7cm but nearly the same rate in AP treatments. Rates of longer than 4cm hypocotyls in cv. Keumseongnogdu, Owoolnogdu were increased with longer AP but their rates of shorter than 4cm showed reverse response to the former. Formation rate and number of lateral roots per sprout were decreased with longer AP, showing more severe decrement when delayed 3 to 4 hour AP. Upper part of hypocotyls and roots were more thickened and shortened in longer AP, respectively. Total fresh weights had no significant difference between AP treatments while hypocotyl fresh weights were increased with longer AP. It was concluded that in mungbean sprout culture aeration from BA treatment to the first watering permitted at least 4 hours.

It shows resistance to mungbean mottle virus, cercospora leaf spot, and powdery mildew in the normal cultivate condition. The average yield of this cultivar shows 1.62 ton/ha, which was 7% more than comparison cultivar.

A new mungbean cultivar Daseon (Vigna radiata (L.) Wilczek) was derived from the cross between KM9003-2B-783 and Keumseong at the Jeollanamdo Agricultural Research ＆ Extension Services (JARES) in 2006. Daseon has erect growth habit, heart leaflet, greenish purple hypocotyl, black and straight pod when matured, and dull green seed surface. A thousand seed weight was 52 g, sprout yield ratio was 630%, and the anthocyanin (delphinidin 3-glucoside) of fresh sprouts contained 1.7 ug/g. The average plant height was 2 cm shorter than the check cultivar (Owool). It is field resistance to mungbean mottle virus, cercospora leaf spot, and powdery mildew. The average yield was 1.76 ton/ha, which was 21% more than check cultivar.

Benzyladenopurine (BA), a synthetic chemical commonly used for bean sprout culture, should be minimized for wellbeing foods or not be applied. The study was done to check the effect of different BA concentrations treated during 5 hour imbibition on growth and morphological characters of mungbean sprouts. The mungbean seeds of 3 cultivars (Keumseongnogdu, Owoolnogdu, and Zhong Lu 1) were imbibed for 5 hours in the solutions with different BA concentrations (0, 25, 50, 75, and 100 ppm) before 3 hour aeration. On the 6th day after culture, the mungbean sprouts were classified by 4 categories on the base of hypocotyl length; > 7cm, 4 to 7cm, < 4cm, and non-germination, and their morphological characters, fresh and dry weights were measured. Regardless of cultivars the composition rate of hypocotyls of longer than 7cm was decreased with increased BA concentration over 50 ppm while the reverse result was true in the rate of shorter than 4cm. In the rate of 4 to 7cm. cv. Owoolnogdu showed the highest rate in its 50 ppm concentration although cv. Keumseongnogdu and Zhong Lu 1 showed similar result to the above two rates. Formation rate and its number of lateral roots were largely changed around 50 ppm concentration but the roots was not formed in over its 75 ppm concentration. Hypocotyl and root lengths of all the cultivars were shortened with increased BA concentration. In the diameter of middle part of hypocotyl, 3 cultivars showed nearly the same responses as the rate of 4 to 7cm hypocotyls. Hypocotyl and total fresh weights per sprout were heavier in BA treated sprouts than in no treated ones but the weights of the former sprouts were not influenced by its different concentrations.

A mungbean cultivar "Munpyeong" (Vigna radiata (L.) Wilczek) was derived as a cross between "Keumseong" and "IT163157" at the Jeollanamdo Agricultural Research and Extension Services (JARES) in 2013. "Munpyeong" has an erect growth habit, heart leaflet, green hypocotyls, black and straight pods when matured, and a dull green seed surface. The stem length of "Munpyeong" was 60 cm, which was 6 cm shorter than that of the control cultivar "Owool." The pod number per plant was 25, which was 3 more than that of the control cultivar. The 1000 seed weight of "Munpyeong" was 45 g, which was 4 g lighter than that of the control cultivar "Owool." Its field resistance to mungbean mottle virus, cercospora leaf spot, and powdery mildew are similar to the control cultivar, whereas its field resistance to lodging was slightly stronger. The hard seed rate of "Munpyeong" was 3.2%, which was similar to that of the control cultivar. The sprout yield ratio was 7.54 times, which was 9% more than that of the control cultivar. The average yield of "Munpyeong" was 1.93 ton/㏊, which was 21% more than that of the control cultivar "Owool" (Cultivar registration number: 5878).

Utilization of synthetic benzyladenine (BA) for bean sprout production should be reduced or minimized because of elevating production cost and not ascertaining action mechanism to human body. The study was done to compare the effects of BA concentrations under different watering methods (overspraying or underwatering) on growth and morphological characteristics of mungbean sprouts. Seeds of cv. Zhong-Lu 1 were soaked for 5 hours in the solutions with different BA concentrations (0, 10, 20, 30, 40, 50 ppm) before 4 hour aeration, and then were cultured for 6 days by both watering systems. Their morphological characters, fresh and dry weights were measured. Regardless of watering methods, lateral roots were sharply dropped over 30 ppm BA concentrations, and hypocotyl, root and total lengths were shortened with increased BA concentrations although ratios of hypocotyl to root lengths and hypocotyl diameters were enlarged with their increment. Total fresh weights were increased up to 20 ppm in overspraying method but up to 30 ppm in underwatering method mainly due to increment of hypocotyl fresh weights. The sprouts were faster grown in overspraying method than in underwatering method because the former showed longer lengths of hypocotyl and root, and total fresh weights.
