Abstract: Longgeng-4311 was bred in Rice Research Institute of Heilongjiang Academy of Agricultural Sciences by using Longgeng-48 as the female parent and Kongyu-131 as the male parent. The average yield of this variety was 8 626.8 kg/hm2 in the regional test, which was 8.1% higher than that of the control variety Longgeng-46, and 9 403.8 kg/hm2 in the production test, which was 9.5% higher than that of Longgeng-46. Longgeng-4311 has the characteristics of early maturity, high yield, good quality, strong comprehensive resistance and wide adaptability. It was approved by Heilongjiang Provincial Crop Variety Certification Committee in 2022 and is suitable for planting in the third accumulated temperate zone of Heilongjiang Province.

黑龍江省第三积温带水稻种植面积超过133.3万hm2,占全省水稻面积的30%以上。该区域的水稻主栽品种为龙粳31,品种过于单一化,种植风险大。虽然近年来黑龙江省水稻育种工作取得了一定的成绩,育成了一批新品种[1],但总体来看综合性状优良的品种少,多数品种仍存在着高产与优质、抗病难以有效结合等问题,因此培育高产与优质并重、兼顾广适多抗的水稻品种至关重要。龙粳4311是黑龙江省农业科学院水稻研究所选育的适宜在黑龙江省第三积温带种植的水稻新品种,具有早熟、优质、多抗等优良特性。该品种的选育与推广,缓解了黑龙江省第三积温带水稻生产上高产与优质、抗病难以有效结合的问题,对保障粮食安全、促进农民增产增收具有重要意义[2]。
