14个小麦新品种（系）的同异分析

为进一步优化小麦品种结构，提高小麦产量和品质，确保粮食和食品安全，采用品种同异比较（理想值法）分析方法，对14个小麦新品种（系）的15个性状进行了综合分析，从中筛选适宜宝鸡生态条件下种植的小麦新品种（系）。结果表明，‘西农167’综合同一度最大(0.9622)，说明该品种在14个参试品种（系）中综合性状表现最好，15个性状中有96.22%的性状达到了育种目标要求，其次是‘漯6073’(0.9104)，产量较高，抗倒伏和综合抗病性强；再次是‘新麦0401’(0.9021)、‘长河25’(0.8954)，均表现为抗倒、抗病，产量三因素协调；对照‘周麦18’(0.8713)，试验中产量中等，但该品种在当地多年表现综合性状较好，高产、稳产，因此，仍不失为一个优良品种。因此，在14个参试品种（系）中，‘西农167’、‘漯6073’、‘新麦0401’、‘长河25’、‘周麦18’等5个品种（系）综合性状表现优异，适宜在宝鸡市川塬灌区生态条件下示范种植。

Similarity-difference Analysis for 14 Wheat Varieties (or Lines)

Abstract: In order to identify and screen new breeds of wheat suitable for planting in the ecological conditions of Baoji, this study proceeded to compare (the idea value approach) the similarities and differences between different varieties of wheat growing there. A comprehensive analysis was made for 15 traits of 14 varieties (families) of the winter wheat varieties grown in the national test site for fine wheat varieties in the southern Yellow River-Huaihe River region in Baoji from 2011 to 2012. The results show that the Xinong 167, Luo6073, Xinmai 0401, Changhe 25 and Zhoumai 18 are new wheat varieties to be suitable for planting and demonstrating under the ecological conditions of plain-highland irrigation area of Baoji.
