“…Berry flavor varies from acidic to sweet and sour. This variability is apparent in the eight races recognized by Peña Lomelí et al (2008) and as well as in other landraces, and wild and weedy varieties recognized locally by traditional farmers.…”

Physalis is an American plant genus that includes species of economic importance for their edible fruit. Consumption of this fruit is a historic tradition in Mexico. Physalis philadelphica is one of the most abundant species, which can grow under wild, weedy or cultivated conditions. It presents high morphological variability in terms of vegetative and reproductive traits; however, no study has been made of its genetic diversity or the impact of human activity on its diversity and differentiation patterns. We determined genetic parameters in nine populations representing a management gradient, including three wild, three weedy and three cultivated populations, using 88 inter-simple sequence repeat markers. The diversity of the total gene pool was high (Ht = 0.292, HT B = 0.319) and did not decrease with the intensity degree of management. Reproductive system, life form and the wide distribution determined the genetic variation of the taxon. AMOVA revealed high variation within the total gene pool (44.3 %) and among populations (46.7 %). This was influenced by pollinator behavior, dispersal form, geographic discontinuity of the studied populations and human selection. Variation among population management categories was lower (9 %), indicating that this variable has little effect, most likely due to the broad gene pool of the taxon. However, analysis of genetic distance and Bayesian assignment distinguished two groups: cultivated and wild, with weedy populations interspersed between. This result suggests that selection for agricultural and morphological attributes of P. philadelphica contributes to this differentiation. Future studies could address the evolutionary dynamics of the wild-weedy-domesticated complex.

“…and P. philadelphica Lam. ), also known as "tomate verde" (green tomato) and "tomate de cáscara" (husk tomato), is a vegetable crop studied in a diversity center in Mexico, and it is widely used in the food sector (Peña-Lomelí et al, 2004;Delgado-Alvarado et al, 2018). Its fruit can be green, yellowgreen, or purple, depending on the cultivated variety (Barroso et al, 2018), and are used to make salads, soups, stews, and sauces (Santiaguillo Hernández & Blas Yáñez, 2009;Barroso et al, 2017).…”

“…However, differences between their flowers and fruit have led many authors to describe these species as distinct (Lagos B. et al, 2005;Zamora-Tavares et al, 2015;Martínez et al, 2017). The flowers of P. ixocarpa are hermaphrodite; however the species is considered cross-pollinated because it shows a selfincompatibility system (Peña-Lomelí et al, 2008); besides, only 40% of its flowers are pollinated, and 30% of the pollinated flowers produce mature fruit (Peña-Lomelí et al, 2004;Santiaguillo Hernández et al, 2012). Likewise, P. philadelphica shows hermaphrodite flowers and is self-incompatible (Zamora-Tavares et al, 2015).…”

“…This is a key point to develop new cultivars better adopted by the production systems. However, there are few morphological and physicochemical characterization studies of P. ixocarpa and P. philadelphica in the literature (Peña-Lomelí et al, 2004;Singh et al, 2013;Naumova et al, 2019), and there are no such studies for the Brazilian conditions.…”

The objective of this work was to estimate the genetic parameters and genetic divergence of two species of Physalis based on fruit traits, as well as the correlations between these traits. The experiment was carried out in a randomized complete block, with three treatments (P. philadelphica and the green and purple varieties of P. ixocarpa), and six replicates. The following traits were evaluated: average fruit mass (AFM), soluble solids (SS), longitudinal fruit diameter (LFD), transversal fruit diameter (TFD), total fruit mass (TFM), number of fruit per plant (NF), reducing sugars (RS), and total sugars (TS). Genetic divergence was estimated by Tocher’s and the UPGMA methods. There was genetic divergence between the Physalis species, with a higher contribution of AFM, LFD, and TFD, mainly by Tocher’s method. A positive correlation was observed between AFM x LFD, AFM x TFD, and LFD x TFD, and a negative correlations between LFD x TFM, TFD x TFM, and NF x RS. The species were discriminated by total sugars. The AFM, LFD, TFD, and TS traits show significant genetic variation and high values of heritability; therefore, they are suitable targets for the genetic breeding of the evaluated Physalis species.

“…Observing the plants in the experimental eld, it was observed that smaller size plants showed more rami cations and consequently more fruiting branches. According toSantiaguillo et al (1998) andPeña-Lomelí et al (2008), the number of branches is an important yield compound in Physalis. This way, PH shows perspectives to be used in indirect selection for yield traits.Total soluble solids were positive correlated with SD (0.355), FPP (0.426), WFP (0.397), LFL (0.199) and TFL (0.249), indicating that plants which have good yield traits tend to have also more soluble solids in the fruits, a good scenery for the genetic improvement of the species.…”

Physalis angulata L. is an American species with edible fruits that stands out for having high nutritional and pharmaceutical value. The species is found in almost the entire Brazilian territory but the consumption of its fruits is not widespread. Genetic improvement is one of the main factors that can make P. angulata a crop in Brazil. The aim of this work was to evaluate the existence of heterosis and heterobeltiosis for morphoagronomic descriptors, to estimate correlations, and to select the best hybrids in P. angulata in a full diallel with five accession. Twenty plant, fruit and seed descriptors were evaluated, and plant height and total soluble solids showed significant genetic variation. Positive heterobeltiosis for total soluble solids was observed in hybrids Pi x G53, Can x Pi and Can x LG, while negative heterobeltiosis for plant height was observed in G53 x LG, Pi x Laj e Can x Laj hybrids. Heterosis was also observed for both descriptors. Using selection indexes, Can x G53, Can x LG, Pi x G53, Can x Pi and G53 x Pi were selected as the best hybrids, expressing smaller plant height and higher total soluble solids.
