A New Short Stem, Lodging Resistance and High Yielding Vegetable Peanut cultivar, “Jopyeong”

A new peanut cultivar “Jopyeong” (Arachis hypogaea ssp. hypogaea L.) was developed at the Yeongnam Agricultural Research Institute, NICS, in Milyang in 2006. It was developed from the cross between the very short stem cultivar “CUP brittle” and the high-yielding cultivar “Daekwang”. “Jopyeong” which is Virginia plant type has 23 branch number per plant with early maturing and ellipse-shaped large kernel. Each pod has two grains with brown testa and 100 seed weight was 87g in the regional yield trials (RYT). This variety also showed more resistant to late leaf spots compared with check one. Especially it has resistance to lodging owing to short stem and erect plant type. In the regional yield trials “Jopyeong” was out-yielded than check variety by 11% with 8.37 ton/ha for fresh pod and by 4% with 3.95 ton/ha for grain.
