Abstract

We bred a mulberry cultivar named 'Saealchan' through local adaptability test, which is under registration as a new cultivar for fruit production. Local adaptability test had been carried out at four local places (Jeonju, Gongju, Jangseong, and Sangju) for five years from 2013. This variety 'Saealchan' belongs to Morus alba L. selected from seedlings collected from mother mulberry 'Shimheung'. Saealchan was resistant to popcorn disease and high yielding variety in fruit productivity by 194% compared to control cultivar 'Shimheung (Morus alba L.)' for three years. Although fruits of 'Saealchan' was smaller in size and lower in sugar content of mulberry fruits compared to control variety 'Shimheung', it showed strong resistance to sclerotial disease compared to 'Shimheung'.
