Growth adaptability analysis of new varieties of color-leafed birch at a young age
【Objective】 The growth performance and stability of new varieties of color-leafed birch were studied under different multi-environment site conditions to provide a scientific basis for selecting excellent new varieties with good adaptability. 【Method】 Six strains of color-leafed birch new varieties and controls were tested at six different sites. A randomized complete block design was used in this study. Each site had 5 blocks, and each plot had 5-15 plants with a 2 m×3 m plant spacing. Tree height, ground diameter, and preservation rate were measured at an early age, and multi-site joint combined variance and stability analyses were conducted using the DPS statistical analysis software. 【Result】 (1) The differences in tree height and ground diameter growth between varieties and locations, and the interaction between varieties by location, were significant (P < 0.01). Therefore, conducting a selection and stability analysis of new birch varieties was important. (2) Among the new birch varieties, the strains RG12 and RG11 showed better growth performance. RG12 had the highest tree height and ground diameter growth at the following four testing sites: Maoershan, Baolongdian, Mengjiagang, and Hegang. RG12 increased by 22.2%, 38.3%, 18.0%, 9.8% and 72.2%, 43.2%, 21.5%, and 19.1% over the population mean, respectively. RG11 had the highest tree height and ground diameter growth at the Xiaobeihu site and increased by 23.3% and 21.5% over local controls, respectively. The tree height growth of Purple 2 in the ‘Zixia’ series performed well in the Cuohai site, with an increase of 9.8% compared to the arerage of the local pilot group. The other color-leafed birch varieties exhibited medium or poor growth performance. (3) Among the six new strains, the conservation rate of the new varieties of the “Zixia” series was 90.1% and was higher than average, while for the new varieties of the “Zhaoxia” series it was 78.7% and was lower than average. (4) Based on the growth and stability parameters of tree height and ground diameter, RG11 was the best variety. 【Conclusion】 The growth traits of color-leafed birch varieties differed significantly, which indicated that variety had a significant effect, as well as location and the variety-location interaction. According to the analysis of trees at a young age, our preliminary results showed that RG11 had rapid growth and stability, and could be promoted at all six testing site regions.
