Effects of fruiting temperature on main agronomic traits of Lentinula edodes populations of different ages
Using the F1 hybrid population of Lentinula edodes L135 and 931 as experimental materials,the effects of fruiting temperature(12 ℃,17 ℃,22 ℃,27 ℃)on the agronomic traits of strain populations of different ages were studied.The results showed that under different fruiting temperatures,the L.edodes age was significantly negatively correlated with the number of primordia,the number of fruiting bodies,and the yield per package,while it was significantly positively correlated with the weight of single mushroom.Moreover,as the fruiting temperature increased,the correlation coefficient between strain age and budding days gradually decreased.The fruiting temperature and strain age could jointly affect the 4 agronomic traits of L.edodes population,including budding days,mushroom picking cycle,yield per package,and single mushroom weight.Increasing fruiting temperature would reduce the effect of strain age.The number of primordia and the number of fruiting bodies were more susceptible to the influence of strain age.The long strain age population was more susceptible to the influence of fruiting temperature than the short train age population.The single mushroom weight,the environmental variance of the single mushroom weight and the number of fruiting bodies could be used as representative screening indicators for the breeding of high temperature varieties of L.edodes.The environmental variance was used as a phenotype to further verify that the single mushroom weight trait was greatly affected by the fruiting temperature.
