以2010—2012年度国家冬麦区长江中下游组小麦区域试验资料和2012—2013年度国家冬小麦品种生产试验汇总资料,对‘镇麦11号’的产量构成因素及其产量的关系进行分析。结果表明:‘镇麦11号’的平均穗数为505.13万?hm2,平均穗粒数为39.31粒,平均穗粒重为1.56 g,平均千粒重为39.78 g,平均产量为6392.89 kg?hm2。相关分析表明,穗数、穗粒数、穗粒重和千粒重均与产量呈正相关,相关程度依次为:穗粒数>千粒重>穗数>穗粒重。通径分析表明,穗粒数对产量的作用最大(直接通径系数 Py =0.5312),其次是穗数(直接通径系数 Py =0.4711),穗粒重的作用最小(直接通径系数 Py =0.0944)。‘镇麦11号’的高产栽培技术应在保证足够的穗数和穗粒重稳定的基础上,主攻穗粒数,同时兼顾粒重。
以2010—2012年度國傢鼕麥區長江中下遊組小麥區域試驗資料和2012—2013年度國傢鼕小麥品種生產試驗彙總資料,對‘鎮麥11號’的產量構成因素及其產量的關繫進行分析。結果錶明:‘鎮麥11號’的平均穗數為505.13萬?hm2,平均穗粒數為39.31粒,平均穗粒重為1.56 g,平均韆粒重為39.78 g,平均產量為6392.89 kg?hm2。相關分析錶明,穗數、穗粒數、穗粒重和韆粒重均與產量呈正相關,相關程度依次為:穗粒數>韆粒重>穗數>穗粒重。通徑分析錶明,穗粒數對產量的作用最大(直接通徑繫數 Py =0.5312),其次是穗數(直接通徑繫數 Py =0.4711),穗粒重的作用最小(直接通徑繫數 Py =0.0944)。‘鎮麥11號’的高產栽培技術應在保證足夠的穗數和穗粒重穩定的基礎上,主攻穗粒數,同時兼顧粒重。

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.
