Analysis of the High-yield and Stable Yield of Baodamai 25 and Its Yield Components
摘要
Abstract
In order to make Baodamai 25 play a greater yield potential in production, the yield, stability, adaptability and yield components of Baodamai 25 were analyzed based on the data of multi-point test of barley in Baoshan City from 2016 to 2017 and reginal test of forage barley in Yunnan Province from 2017 to 2019.Results showed that the yield, stability and adaptability of Baodamai 25 were better than those of the control varieties.The correlation degrees of main agronomic traits with yield from high to low was as follows: filled grain number per panicle (0.3973), effective panicle ( 0.3560 ), total number of tillers (0.2052), plant height (0.1550), 1000-grain weight (0.0707), basic seedlings (0.0003).The direct effects on yield from high to low were as follows: filled grains per panicle ( 0.4987 ), 1000-grain weight (0.4249), effective panicles (0.3605), plant height (0.2683), total tillers (0.2335), basic seedlings (0.0652).The correlation de-gree with yield from high to low was as follows: grain number per panicle (0.4611), plant height (0.4583), effective panicles (0.4377), 1000-grain weight (0.4180), total tillers ( 0.3866), basic seedlings (0.3642).关键词
