摘要
对 1997～ 2 0 0 1年度洛旱 2号的区试及品种比较试验结果进行分析 ,结果表明 :洛旱 2号具有综合抗性好、抗旱、中早熟、适应性广的特点。在产量性状方面 ,分蘖力强 ,成穗率中等 ,成穗数多 ,产量三要素协调 ,高产稳产性好 ,是适宜河南省旱地种植的一个理想品种。通过对洛旱 2号的选育分析认为 :旱地小麦品种性状的改良应注重运用水旱交叉选择 ,在保证其抗旱性的基础上提高其丰产稳产性能。
The experiment in Luoyang No. 2 from 1997 to 2001 indicated that the variety had the character of good integrated resistance, early-middle maturation and wide adaptation, and the yield components: strong tillage ability, middle rate of panicle formation and high number of panicle. High and stable yield of Luohan No.2 could be obtained based on the coordination three yield components. The analysis of breeding procedure of Luohan No.2 indicated that the method of irrigation and upland culture in turn was best method for the selection of upland wheat variety.
