Analysis on the main characteristics and yield components of‘Zhenmai 11’
摘要
Abstract
The relationship between yield components and yield of ‘Zhenmai 11’was analyzed by the data of wheat regional trials of middle and lower reaches of the Yangtze River in the national winter wheat region in 2010—2012 and the data of wheat production tests of lower reaches of the Yangtze River in the national winter wheat region in 2012—2013.The results showed that the average number of spikes,the average grain number per spike,the average grain weight per spike,the average 1 000-grain weight and the average yield of ‘Zhenmai 11’ were 505.13 ×104 ?hm2 ,39.31,1.56 g,39.78 g and 6 392.89 kg?hm2 respectively.Correlation analysis showed that the spike number,grain number per spike,grain weight per ear and 1 000-grain weight were positively asso-ciated with yield.The correlation degree was as follows:grain number per spike,1 000-grain weight,spike num-ber,grain weight per spike.Path analysis showed that the grain number per spike was the most important to yield (direct path coefficient Py =0.5312),followed by the spike number(direct path coefficient Py =0.4711 ),the grain weight per spike was the least(direct path coefficient Py =0.0944).The high yield cultivation technique of‘Zhenmai 11’should be based on the guarantee of sufficient number of spike and grain weight,taking the grain number per spike as the main target,and giving consideration to the grain weight.关键词
