节水抗病小麦新品种科茂53的品质分析

Quality Analysis of a New Wheat Variety Kemao 53 with Water Saving and Disease Resistance

科茂53是高碑店市科茂种业有限公司选育而成的小麦新品种,2019年6月通过河北省审定(冀审麦2019023号)。为更进一步了解其生产特性,以2016—2018年2个年度河北省冀中北小麦区域试验结果为数据,对科茂53的丰产性、稳产性和抗逆性进行了分析。结果表明,科茂53的丰产性、稳产性好,平均籽粒产量7530.0 kg/hm^(2),较对照增产6.9%;穗数为613.5万/hm^(2),穗粒数为36.0粒,千粒重为41.8 g;穗数、千粒重均与籽粒产量呈正相关,穗粒数与产量呈负相关;穗数对产量的直接作用最大,千粒重次之,穗粒数的作用最小。因此,在生产中通过增加有效穗数来提高千粒重,能够进一步发挥该品种的增产潜力。

A new wheat variety Kemao 53 was approved by the Crop Variety Certification Committee of Hebei Province in June 2019,which was cultivated by Gaobeidian Kemao Seed Co.,Ltd..In order to fully understand the variety characteristics of Kemao 53,we analyzed the fertility,stability and resistance of Kemao 53 based on the data of two years regional wheat test in North-central Hebei in 2016-2018.Results showed that Kemao 53 had good stability and adaptability.The average yield of Kemao 53 regional test was 7530.0 kg/hm^(2),which was 6.9%higher than that of the control.The number of effective panicles was 613.5×10^(4)/hm^(2) with 36.0 grains per panicle and 41.8 g 1000-grain weight.The 1000-grain weight and panicle number were positively correlated with yield,while grains per panicle was negatively correlated with yield.The panicle number was the main factor affecting the yield of Kemao 53,1000-grain weigh had little effects,while grains per panicle showed the least influence.Thus,yield could be enhanced by increasing the panicle number and 1000-grain weight in production.
