摘要
[目的]鉴定旱稻新品种的丰产性、适应性、综合抗性。[方法]采取大田随机区组设计，比较15个旱稻品种的生长及产量表现。[结果]参试品种全生育期为115～131 d；株高分布为85．9～109．4 cm；整齐度均较好；绿旱6号落粒性表现为较难；抗倒性以隆旱1号、绿旱3号、旱优88及绿旱6号、国旱47、绿旱1号表现为好或较好；米质普遍较差；参试新品种中，有8个品种较对照增产，增幅较大的是旱优73、旱两优212、红旱8号，分别较对照增加36．09％、18．54％、18．26％。[结论]主要推荐绿旱6号在沿淮周边地区示范种植，亦可以推广旱优73、旱两优212，但要注意后期倒伏。
Abstract
Objective] The aim was to identify high yield, adaptability and comprehensive resistance of new varieties of upland rice.[Method] Using field randomized block design, the growth and yield performance of 15 upland rice varieties were compared.[Result] The whole growth period of tested varieties were 115-131 d; plant height was 85.9-109.4 cm;the uniformity was good;seed holding of Lvhan 6 was difficult;lodging resistance of Longhan 1, Lvhan 3, Hanyou 88 and Lvhan 6, Guohan 47, Lvhan 1 was good or relative good;rice quality was poor;among tested new varieties, yield of 8 varieties was increased compared with CK, the significant increasing was Hanyou 73(36.09%), Hanliangyou 212 (18.54%), Honghan 8 (18.26%).[Conclusion] Lvhan 6 was recommended to be cultivated in the surrounding area;Hanyou 73, Hanliangyou 212 could also be popularized, but we should pay attention to late lodging.
