Detailed Introduction to Rice Variety Minghui 63
[Basic Information] Minghui 63 was crossed as the female parent with Nannong 3005. Starting from the F2 generation, excellent individual plants were selected, and high-quality grains were selected through brown rice selection. South propagation was used to advance generations year after year, with seasonal selection in Yangzhou, and inoculation identification for resistance. In the F5 generation, paired test crosses were made with Xieqingzao A. In the 1994 main season, recovery ability and heterosis identification were conducted. Among the 121 identification lines selected, line No. 41 performed most outstandingly, with good plant and leaf morphology, coordinated panicle and grain structure, more panicles in the testcross F1, good luxuriance, plump and full grains, high seed-setting rate, and relatively good grain quality. This line was then further

How to Identify and Control Southern Rice Black-Streaked Dwarf Virus
Southern rice black-streaked dwarf virus is a rice viral disease occurring in southern rice-growing areas, with characteristics of strong explosiveness, rapid spread, great difficulty in prevention and control, and heavy damage losses. Rice and corn infected at the seedling stage will basically suffer total crop failure. In 2011, after comprehensive prevention and control, a total of about 8,500 mu of southern rice black-streaked dwarf virus occurred in Lianyuan City, of which the affected area of middle-season rice was 6,500 mu, the affected area of late rice was 1,600 mu, and the affected area of corn and other crops was 400 mu. A total of 25.93 tons of rice was lost, of which
