万优66是以籼型三系不育系万8A为母本,优质抗稻瘟病恢复系万恢66为父本配组育成的中迟熟三系杂交水稻品种。本文总结了该品种在福建武夷山地区引种的特征特性及高产栽培技术。2022—2024年,该品种在武夷山市进行多点展示和示范试验,表现出生育期适宜、分蘖力强、穗结构匀称的特性;产量在8 349.4~9 596.0 kg/hm2;抗稻瘟病、抗倒伏性好;整精米率高、米质外观好、适口性好。其高产栽培技术包括选择适宜播期(4月下旬至5月上旬),根据不同移栽方式调整播量;通过药剂浸种、多效唑化控、“送嫁肥+送嫁药”施用等处理培育壮秧;合理密植,构建高效群体;推行“重基肥、早追肥、补穗粒肥”的施肥策略,并结合“浅水、晒田、干湿交替”的水分管理模式,促进植株分蘖成穗与抗倒伏;施用16%甲维·茚虫威150 g/hm2等药剂防治二化螟等病虫害;稻穗90%成熟时抢晴天收获。本文为该品种在相关地区的推广种植提供参考。

Wanyou 66 was a mid-late maturing three-line hybrid rice variety using the indica-type three-line sterile line Wan 8A as the female parent and the high quality, blast-resistant restorer line Wanhui 66 as the male parent. The characteristics and high yield cultivation techniques of this variety were introduced in the Wuyishan region of Fujian Province. From 2022 to 2024, multi-location demonstration and trial experiments of this variety were conducted in Wuyishan City. It was characterized by a suitable growth period, strong tillering ability, and uniform panicle structure in field cultivation. The yield ranged from 8 349.4 to 9 596.0 kg/hm². The variety exhibited resistance to rice blast and good lodging resistance, as well as a high head rice rate, good grain appearance, and desirable palatability. Its high yield cultivation techniques included selecting an appropriate sowing date (late April to early May) and adjusting the seeding rate according to different transplanting methods; cultivating strong seedlings through treatments such as chemical seed soaking, paclobutrazol application, and “farewell fertilizer and farewell pesticide” before transplanting; achieving reasonable planting density to establish an efficient population; implementing a fertilization strategy of “heavy base fertilizer, early topdressing, and supplemental panicle and grain fertilizer” combined with a water management model of “shallow water, sun-drying, and alternating wet and dry conditions” to promote tillering, panicle formation, and lodging resistance; applying pesticides such as 16% emamectin benzoate·indoxacarb at 150 g/hm² to control pests like the rice stem borer; and harvesting under sunny conditions when 90% of the panicles were mature. This study provides a reference for the promotion and cultivation of this variety in relevant regions.
