, which is essential for the sexual reproduction of C. oleifera and is closely associated with the breeding of this plant. Fig. 1. The tree body, floral organs, and pistil of Camellia oleifera : ( A ) the adult tree body, ( B ) the floral organ, ( C
Jatropha ( Jatropha curcas L.) has been considered a promising species for biofuel production. However, jatropha is still considered undomesticated and breeding and genetic improvement programs are needed. In this context, germplasm collection and
impact on fruit growth, nut size, and kernel size in macadamia. According to Fattahi et al. (2014) , hazelnut nut weight was significantly affected by pollen source, whereas self-pollination reduced its nut and kernel trait values and increased the
% shading, whereas heavier shading reduced yield significantly. In larger shrubs, Hampson et al. (1996) observed greater yield loss from shade in two cultivars of hazelnuts, with losses of 45% in 30% shade and 82% reduction in 92% shade. Overall, our
the intersectional group as a result of the limited parent pool used in breeding. There was large variability in the herbaceous peonies, possibly as a result of the high number of cultivars used in our studies and the different species involved. The

. Moreover, the relationship between green period, calculated using predicted sigmoid curves, and foliar cold tolerance, measured using LT 50 , was studied to provide a theoretical basis for molecular marker-assisted breeding of new cultivars that combine the
herbicide residues from a hazelnut planting into some bean plots. The time of measurement after pods were harvested is important for interpreting these data, and between the residual herbicide and the longer period of evaluation in 2019, the second-year data
demographic equilibrium ( Jump et al., 2009 ). Wild species generally contain more genetic variability than cultivated species ( Klepo et al., 2013 ). This naturally occurring variation in wild species is an underexploited resource for plant breeding as a
