“…In this experiment, the correlation between the growth traits was always strong and positive, similar to other plants [36][37][38]. These results may provide a rationale for indirect selection for growth traits.…”

Broussonetia papyrifera (L.) L’Hér. ex Vent, a perennial deciduous tree, is used in feed, medicine, papermaking, environmental protection, and ecological restoration. This paper ttook 33 provenances from the natural distribution as the research objects, observes their growth and nutritional traits, and analyzes the laws of geographical variation. The repeatability was 0.80–0.88 and 0.48–0.91, respectively. The correlation was significant (the correlation coefficient was 0.764). The variation is greatly affected by the latitudinal direction. Through clustering, the 33 provenances were clustered into 4 groups and most provenances with relatively close geographical origins were clustered together, showing differences between different geographical regions. Using leaf biomass (0.4662 g) and crude protein content (14.39%) as the selection index, the Sichuan Mianyang (SCMY), Chongqing Kaizhou (CQKZ), Shanghai (SH), and Fujian Nanping (FJNP) provenances were selected as fast-growing, high-yield, and high-quality paper mulberry provenances. This study provides the basis for the selection of excellent paper mulberry trees.

“…According to Pimentel-Gomes and Garcia (2002), values of CV e ranging from 10 to 20 % in field experiments with high competition can be classified as low to moderate and above 20 % as relatively high (which includes all traits in the present study except stem straightness). However, this classification does not take into account different genetic and environmental factors, and it is common in field-level tree provenance and progeny tests to have CV e levels higher than 20 % (Kubota et al, 2015;Lima et al, 2015;Martins et al, 2018).…”

Genetic control of silvicultural traits in Balfourodendron riedelianum (ENGL.) ENGL.

et al. 2019

The Atlantic Forest has very high levels of biodiversity and is considered one of the most important and threatened biomes in the world. Balfourodendron riedelianum is one of the forest’s characteristic tree species that is currently under considered endangered due to timber extraction and forest fragmentation. With the goal of generating information that may contribute to the genetic conservation of B. riedelianum, genetic parameters are estimated for quantitative traits important for silviculture in a provenance and progeny test located in the Experimental Station of Luiz Antônio, São Paulo State, Brazil. The test was established in 1986 and consists of three provenances, from which open-pollinated seeds from 19 seed trees were collected. The following traits were evaluated at 32 years of age: diameter at breast height (DBH), total height (H), stem height (SH), stem straightness (SS), and forking (FOR). The estimates were carried out using the REML/BLUP method. Significant genetic variation among progenies was detected for all traits (except SH) and between provenances for DBH. The coefficient of individual genetic variation (CVgi) ranged from 2.5 to 9.5 %. The mean heritability among progeny ( $h_f^2$ ) was substantial for DBH (0.44) and FOR (0.36), enabling the selection of families with the highest DBH and lowest FOR for population improvement. Genotypic and phenotypic correlations among traits were also found. We conclude that there is genetic variability in the population that can be exploited in future breeding programs and for the genetic conservation of the species.

“…For PBAU, the mean H was 11.13 m, DBH 14.33 cm and MCD 4.44 m. The mean development of PSEL was similar, with a mean H of 11.0 m, DBH of 14.19 cm and MCD of 4.18 m. According to Martins et al (2018), the mean H was 11.93 m and DBH was 14.50 cm when this population was 31 years old. Therefore, the development of M. urundeuva populations was similar to that observed in the literature for long-lived tree species, characterized by a slower growth than that of exotic commercial species.…”

“…Among the economically relevant traits for breeding of tree species for wood production are growth (height), diameter at breast height (DBH), stem form and adaptation (survival). Estimates of genetic parameters for these traits in M. urundeuva indicate genetic variation among and within provenances, which can be used for genetic conservation and breeding purposes (Freitas et al 2007, Tung et al 2011, Moraes et al 2012, Pupin et al 2017, Martins et al 2018).…”
