The parental sources, breeding process, and characteristics of hybrid rice variety Xiliangyoujingsizhan were introduced, and its high yield cultivation and seed production techniques were summarized. This variety is a high quality hybrid rice variety developed from Xi06S as the female parent and Xijingsizhan as the male parent. It is suitable for planting as mid season rice in the middle and lower reaches of the Yangtze River and has excellent field growth, high quality, moderate resistance to rice blast disease, and high yield. The high yield cultivation techniques include timely sowing and soaking with pesticides before sowing; transplant seedlings at around 25 days of age to ensure a basic number of 900 000 to 110 000 plants/hm2; apply sufficient basal fertilizer, apply tillering fertilizer early, and supplement phosphorus and potassium fertilizers according to plant growth in the later stage; after 7 days of transplantation, use pesticides such as butachlor to control weeds in the field; apply 43% tebuconazole and other pesticides to prevent and control diseases and pests such as rice blast disease, sheath blight, and rice planthoppers. High yield seed production techniques include selecting plots with sufficient light, medium to high fertility, and convenient drainage and irrigation for seed production, and paying attention to seed isolation; reasonably arrange the parents’ broadcasting schedule; apply organic fertilizer and deeply plow before sowing, keep the field moist after sowing, and apply fertilizer at appropriate times; timely spray gibberellin “920”, and arrange manual powder milling when the heading rate of the parent plants reaches 50%; according to the actual situation in the field, remove impurities and timely prevent and control diseases and pests in the field; harvesting with a specialized harvester at around 85% maturity of the seeds. This article provides a reference for promoting and planting this variety in relevant regions.
