摘　　要：培育耐盐碱水稻是开发利用盐碱地最经济有效的途径之一。湖南杂交水稻研究中心以深08S为母本、GD-7S×广占63S的F2代中的优良单株为父本杂交,后代经三亚和长沙穿梭加代育种,选育出了光温敏核不育系箐196S;以粤农丝苗为母本、象牙香占为父本杂交,后代经系谱选择和分子检测,培育了抗稻瘟病、米质优、综合性状良好的恢复系R3261。随后,三亚市国家耐盐碱水稻技术创新中心和湖南杂交水稻研究中心用不育系箐196S与恢复系R3261配组育成两系杂交水稻新组合箐两优3261。该组合具有株叶形态优良、生育期适中、分蘖能力强、稻米品质好、耐盐、耐高温和抗倒伏等特点,2024年分别通过湖南省和国家农作物品种审定委员会审定,可在湖南省作中稻种植,在华南盐碱地作晚稻种植,推广应用前景广阔。Developing saline-alkali tolerant rice is one of the most economical way to exploit and utilize saline-alkaline land.In this study,a photo-thermo sensitive genic male sterile line Jing 196S was developed by Hunan Hybrid Rice Research Center(HHRRC)with Shen 08S as the female parent and an excellent individual plant in the F2 population from a cross between GD-7S and Guangzhan 63S as the male parent for hybridization,followed by generations of shuttle breeding in Sanya and Changsha.At the same time,a restorer line R3261 with resistance to rice blast,good grain quality and excellent comprehensive traits was developed by HHRRC from the hybridization with Yuenongsimiao as the female parent and Xiangyaxiangzhan as the male parent through pedigree selection and molecular detection.The National Center of Technology Innovation for Saline-alkali Tolerant Rice in Sanya and HHRRC made a cross with the male sterile line Jing 196S and the restorer line R3261 and develop the new two-line hybrid rice combination Jingliangyou 3261.The hybrid combination was characterized by excellent plant type,moderate growth period,strong tillering ability,good grain quality,salt tolerance,high temperature resistance and lodging resistance.It was approved by Hunan Provincial Crop Variety Appraisal Committee and National Crop Variety Appraisal Committee in 2024,respectively.This combination is suitable for planting as mid-season rice in Hunan Province and as late rice in saline-alkali land in South China,demonstrating broad application prospects.
