许052×白330是我所1976年育成的白粒单交种。其株高250厘米,穗位125厘米,植株健壮,叶色浓绿,直到收获时下部叶片仍保持青绿,生育期130天,穗大、粒大,千粒重400—420克,每穗12—14行,每行40—45粒。具有高抗大小斑病、高产的优点。 1976年秋苗期抗小斑病鉴定,即表现高抗小斑病,1977年苗期及成株期抗病鉴定试验亦表现高度抗病。 1977年在静海县东双塘大队参加品比试验,结果许052×白330亩产813斤,分别比反帝105、中单2号、京白10号增产91％,44％,30％;
Xu 052 × white 330 is my 1976 bred white single breeding. The plant height of 250 cm, spike 125 cm, plant robust, dark green leaves until the lower leaves remain green when harvesting, growth period of 130 days, spike, grain size, grain weight 400-420 grams, 12-14 OK, 40-45 tablets per line. High resistance to size spots, high yield advantages. In the autumn of 1976, the identification of small spot resistance showed that it showed high resistance to small spot disease. In 1977, the disease resistance test at seedling stage and adult stage also showed highly resistance to disease. In 1977, Dongshuitang Battalion of Jinghai County participated in the product ratio test. As a result, the output of Xu 052 × W 330 was 813 kg, an increase of 91%, 44% and 30% respectively over that of the Anti-Imperialist 105, Zhongdan 2 and Jingbai 10;
