1. Variety characteristics Jingdan 841 is disease-resistant, lodging-resistant, hi-fat, waterlogging tolerant, saline-alkali tolerant, high yield potential, high seed yield, good eating quality and green stalks and green leaves at maturity. 2. Yield performance The variety in 1987, 1989 and 1990 to participate in the Beijing municipal test, the output ranked first, second and third, respectively, compared with the reference “Beijing hybrid No. 6 ” increased respectively 13.1%, 31.0 % And 39.2%. In 1989, in the two-acre trial site of Wei Shanzhuang in the suburbs of Beijing, Beijing alone produced 734.5 kg of 841 mu of 841 mu per mu, an increase of 10.7% over that of the “Nongda 60”.
