“…Annicchiarico et al (2010) suggested that to predict superior genotype, considerations of heritability must be combined with genetic gains in the tested traits. High heritability coupled with high genetic gains indicated the additive gene effects, whereas high heritability coupled with low genetic gains indicated non-additive gene effects (Atnaf et al 2017;Nehe et al 2019;Sudrajat et al 2018). The yield had high heritability and genetic gains in the mutant population, but the cross-bred population had moderate heritability and low genetic gains.…”

Abstract. Amien S, Maulana H, Ruswandi D, Nurjanah S. 2021. Genetic gain and relationship of yield and yield attributes of mutant and cross-bred stevia (Stevia rebaudiana) genotypes. Biodiversitas 22: 3119-3126. Plant breeding programs involved many traits and genetic parameters in the selection process. The information on genetic parameters on yield and other related traits provided an overview for breeders and farmers in selecting new superior genotypes. The purpose of this study was to estimate genetic parameters including heritability and genetic gains in yield and other traits, to determine the relationship between various traits, and to select superior stevia (Stevia rebaudiana Bertoni) genotypes for each trait. Field experiments were carried out in two planting environments, namely, the highlands and the medium plains employing a randomized completed block design and each genotype was three replicates. The results showed that the yield had high heritability and genetic gains ??in mutant populations, whereas cross-bred populations had moderate heritability and low genetic gains. Stem weight (SW) and number of leaves (NoL) traits were identified as having high heritability and genetic gains in both populations. The GT biplot measurement showed that the yield was identified to have a significant and positive correlation with SW (p<0.05). H4 was correlated with Number of branches (NoB), Yield, SW, and chlorophyll content (Chl) traits in the cross-bred populations. H9 excelled on and was correlated with NoL and plant height (PH). M11 was identified to be highly correlated with NoL, PH, NoB, and Chl traits in the mutant populations, while M15 excelled on and was correlated with yield and SW. The results of this study revealed that there was a potential for improvement in the traits tested of stevia through cross-bred and mutant populations in different environmental conditions. The selected genotypes can be developed in a suitable environment and used for further stevia plant breeding programs.

“…In this study, the diversity of seed germination capacity between provenances was very high, ranging from 53.5% to 82.8%. High variability in germination between populations was also reported in Nothofagus glauca (Moya et al 2017) and Sterculia foetida (Sudrajat et al 2018).…”

“…Germination capacity before and after storage was quite varied between provenances. Diversity of seed germination and storability among provenances were also reported in Swertia chirayita (Pradhan and Badola 2012) and S. foetida (Sudrajat et al 2018). Seed germination after storage for 5 years was significantly negatively correlated with initial seed moisture content (r 2 = -0.933).…”

Abstract. Sudrajat DJ, Rustam E, Widyani N. 2022. Provenance variation in seed storability of jabon (Neolamarckia cadamba) and their response to seed invigoration by priming and gamma irradiation treatments. Biodiversitas 23: 5074-5084. Jabon (Neolamarckia cadamba (Roxb.) Bosser) is a tree species native to Indonesia with a wide growth distribution and high economic potential, but the cultivation of this species is often hampered by low seed viability and vigor, especially for seeds that have undergone storage. This study aims to examine the provenance variation in seed germination and storability of N. cadamba and the effectiveness of invigoration treatments on the stored seed for 5 years. Hydro-priming, osmo-priming, hormone-priming, and gamma irradiation were tested to improve seed germination and seedling growth. The results showed that intra-population variation in seed germination and storability is quite high, ranging from 53.5%-82.8% for germination capacity and rate of germination decline ranging from 0.7%-61.6% after 5 years of storage. Pomalaa provenance had the best seed germination and storability compared to other provenances. The invigoration treatment significantly affected germination and seedling growth of all provenances. Hydro-priming with aquades for 48 hours gave the best germination capacity for Pomalla and Batuhijau provenances. For low initial germination, such as seed from Kapuas, Alas Purwo, and Kampar, the GA3 500 ppm for 48 hours and PEG -1.2 MPa for 24 hours treatments could improve seed viability and vigor. GA3 and gamma irradiation gave the best seedling growth, although other treatments, such as PEG -0.8 MPa for 24 hours, also could increase seedling height and biomass of Kampar provenance. In general, the effectiveness of the invigoration treatment depends on the initial physiological conditions, the invigoration method, and its concentration.

“…Differences in fruit, seed and seed germination characteristics of N. orientalis were also reported by [22] by examining its four natural habitats, i.e., swamps, temporal swamps, dry land, and temporal swamp savanna. Several studies have reported that differences in the morphophysiological characteristics of fruit and seeds from different population or provenance are strongly influenced by genetic factors [18,23,24,25]. Differences in mother tree of N. orientalis also affect the growth of seedlings in nurseries [26].…”

The aim of this study was to identify the morpho-physiological diversity of seeds in several mother trees of N. orientalis at 6-year-old in a seedling seed orchard in Parungpanjang, Bogor and to identify the effectiveness of seed sortation in improving the seed germination. A total of 17 mother trees were collected for their fruit, measured the morphology of the seeds and tested their germination. The results showed that fruit and seed dimensions and weight, germination capacity were strongly influenced by the mother tree. Germination capacity and the highest germination capacity was resulted by family no. 22-BT (90%) and 48-MJ (92%). The highest coefficient of variation was given by seed weight per fruit (83.03), followed by germination capacity (66.66) and fruit weight (65.95). Seed sortation had a significant effect on germination capacity, germination rate, and mean germination time, but had no significant effect on germination value. In general, a sieve size of 300-420 μm gave the best results for increasing germination capacity (59.5%), germination rate (1.67% day-1), and mean germination time (18 days). Other sieve sizes, i.e., 420-600 μm was also able to improve seed germination so that for seed sortation applications 300-600 μm sieve sizes can be used.
