摘 要:对108份"西农"系列、"宛麦"系列小麦新品系在南阳地区的抗性、产量性状进行分析,探究适应南阳气候的小麦特征,为小麦新品种选育提供参考.结果表明:冬性品系容易遭受冬季冻害,春性品系容易遭受春季冻害;大部分品系对条锈病和叶锈病表现出较好的抗性,白粉病很少发生,全部品系均遭受赤霉病病害.对筛选出的16个抗性好、产量高的品系作进一步分析,发现冬前蘖与基本苗呈极显著正相关,穗粒数与春季蘖和穗数呈极显著负相关,穗数与冬前蘖呈显著正相关.在满足综合抗病性好的基础上,冬前发育稳健且春发能力强的品系能够增强抗寒性、增加穗数、协调穗粒数,容易获得高产.In order to provide a reference for new variety breeding,the characteristics of wheat which could adapt to Nanyang climate were explored in this study.108 new wheat strains containing Xinong series and Wanmai series were analyzed between resistance and yield.The results showed that winter varieties were easy to suffer from the winter cold,while spring varieties were easy to suffer from the spring cold.Most of the strains showed good resistance for stripe rust and leaf rust,powdery mildew was rare,all strains were suffered from gibberellic disease.16 strains were screened which containing good resistance and high yield.Winter tillers and number of seedling had significantly positive correlation,the relations of grains per spike to spring tillers and to spike number were significant negative correlation,spike number and winter tillers was significant positive correlation.Development steady before winter and growing fast in spring could enhance hardiness and spike number,besides it could coordinate the grains per spike,finally it was easy to obtain a high yield.
