摘要: 【目的】 评价引进哈萨克斯坦春小麦品种(系)的抗旱性,为我国新疆春小麦抗旱品种的选育提供参考。【方法】 使用20%的PEG-6000高渗溶液模拟干旱胁迫,采用综合耐旱系数法和灰色关联度分析法分析了参试小麦品种(系)的芽期抗旱性。【结果】 引进春小麦的芽长5.25~87.41 mm、胚芽鞘长5.25~40.18 mm、根长21.67~98.65 mm、芽鲜重0.02~0.43 g、根鲜重0.02~0.64 g、芽干重0.004~0.09 g和根干重0.01~0.16 g,各性状的测量值都有所下降,芽受干旱胁迫的影响比根大。【结论】 抗旱性较好的品种(系)有11个,依次为C1429(Д 12 Зритроспермнм)、C1442(Д 315)、C1446(Д 320)、C1428(Д Бт-10)、C1439(Д 311)、C1441(Д 314)、C1440(Д 313)、C1444(Д 318)、C1423(54427)、C1443(Д 316)和C1431(Д 254 No6, сар.29)。

Abstract: 【Objective】 The purpose of this study is to scientifically evaluate the drought resistance of imported spring wheat varieties(lines) from Kazakhstan, and to provide help for the breeding of drought resistant spring wheat varieties in Xinjiang. 【Method】 The measured values of imported spring wheats' bud length were 5.25-87.41 mm, germ sheath length were 5.25-40.18 mm, root length were 21.67-98.65 mm, bud fresh weight were 0.02-0.43 g, root fresh weight were 0.02-0.64 g, bud dry weight were 0.004-0.09 g,and root dry weight were 0.01-0.16 g.The measured values of each trait decreased under drought stress, and the bud was affected by drought stress more than the root. 【Result】 The measured values of bud length, germ sheath length, root length, bud fresh weight, root fresh weight, bud dry weight and root dry weight of imported spring wheat all decreased under drought stress, and the bud was affected by drought stress more than the root. 【Conclusion】 There were 11 varieties (lines) with better drought resistance: C1429 (Д 12 Зритроспермнм), C1442 (Д 315), C1446 (Д 320), C1428 (Д Бт-10), C1439 (Д 311), C1441 (Д 314), C1440 (Д 313), C1444 (Д 318), C1423 (54427), C1443 (Д 316) and C1431 (Д 254 No6, сар.29).
