旱稻新品种比较试验

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。

A Comparison Test on New Varieties of Upland Rice

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.
