皖北地区高产小麦品种产量形成特性研究

选用烟农19、中麦578、伟隆169、华成1688、安农1589、天益科5号、荃麦725、安农0711、西农99、华展199和中育1211共11个适宜皖北地区种植的小麦品种，研究分析了各小麦品种的产量、群体动态变化、干物质转运积累与分配等特性。结果表明，11个供试小麦品种产量均达到7 000 kg·hm^-2以上，属高产小麦品种；其中伟隆169、荃麦725、西农99和华展199的产量都达到了8 000 kg·hm^-2以上，产量构成协调，穗数及成穗率较高，并且干物质积累量、干物质在籽粒中的分配量以及干物质转运量高于其他品种。相关分析表明，产量与分蘖成穗率呈显著正相关,与穗数呈极显著正相关，伟隆169、荃麦725、西农99和华展199 穗数、分蘖成穗率较高，具有较高产量，适宜皖北地区推广种植。

Study on yield formation characteristics of high-yielding wheat cultivars in Northern Anhui

Eleven wheat varieties suitable for planting in Northern Anhui were selected, including Yannong 19, Zhongmai 578, Weilong 169, Huacheng 1688, Annong 1589, Tianyike No. 5, Quanmai 725, Annong 0711, Xinong 99, Huazhan 199 and Zhongyu 1211, to study and analyze the characteristics of yield, population dynamic change, dry matter transport, accumulation and distribution of each wheat variety. The results showed that: the yields of the 11 tested wheat varieties reached more than 7 000 kg·hm^-2, belonging to high-yielding wheat varieties, and among them, the yields of four wheat varieties, Weilong 169, Quanmai 725, Xinong 99 and Huazhan 199, reached more than 8 000 kg·hm^-2; the yield composition was coordinated, the number of panicles and panicle rate were high, and the dry matter accumulation, dry matter distribution in grains and dry matter transport were higher than those of other varieties. Correlation analysis showed that yield was significantly and positively correlated with the tiller spike rate and highly significant positive correlated with the spike number. The four wheat varieties, Weilong 169, Quanmai 725, Xinong 99 and Huazhan 199, had high panicle number and tiller panicle rate and high yield, indicating which are suitable for popularization and planting in Northern Anhui.
