Nikolay Panayotov Agricultural University of Plovdiv, 12 “Mendeleev” Str., Plovdiv, Bulgaria Abstract The main goal of the present study was to establish the morphological behaviors and productivity of different genotypes of cape gooseberry (Physalis peruviana L). The experiments with six genotype of cape gooseberry with different origin were carried out. Plants were grown by the conventional technology for Bulgaria with sowing in the middle of March and transplanting in the middle of May on scheme 70 x 50 cm. In phase of full botanical maturity the morphological characteristic was done. The height and weight of central stem; number and weight of branches; number and weight of leaves; number and weight of fruits of one plant were investigated. The productivity was determinated. The correlations between the investigated parameters were calculated. With the biggest height and weight of stem were the plants with origin from Turkey. The number of branches was the highest in Obrzaec 3 with origin from the USA. The highest productivity was recorded form variety Plovdiv, while the lowest one from genotype 11-2012 that originate from Germany. Key words: vegetative, fruit, productivity, morphology, correlation INTRODUCTION The genus physalis covers approximately 100 annual and perennial species used for their fruit. The most widespread is Physalis peruviana L., followed by Physalis pruinosa L., Physalis ixocarpa Brat. and Physalis pubescens L. (Moriconi et.al. 1990, M. Crawford, 2004). In order to identify the different species and determine their taxonomic identities are investigated numerous morphological and anatomical characteristics of separate organs. Main trend primarily of all of these studies is to reveal significant differences for systematic differentiation. Li and Tores (1997) reported that some of the anatomical characteristics of stem allow themselves to be used to distinguish between some of the species and varieties of Physalis angulata, Physalis lagascae, Physalis peruviana and Physalis pubescens, arguing and they emphasised that only in Physalis peruviana L. in the stem was observed the presence of spongy zone. In other studies, the same authors Li and Torres (1997a) revealed the possibility of finding the belonging to the genus Physalis, as well as to separate variety by the number of vascular vessels in the central part of the petiole, the type of stomata and trichomes and density of the pappus. Garcia (1997) indicates that individual species and varieties differ also by vasiculars on the top and bottom side of the leaves, the length of the pappus on the underside of leaves and length and stomata index and the thickness of mesophilic tissue. Haytova and Babricov (2006) and Haytova and Gergova (2011) established strong genotypic response studied a wide range of varieties in various vegetable crops. Specific morphology-anatomical features of the fruit between different species and varieties according to Dyki et al. (1997) are the type of waxy cells on the surface, the presence or absence of hairs, the type of epidermal cells, and pericarp, available-vascular vessels. Zhang and Wen (1996) in this direction included also the surface of the seed coat. Comparatively good productivity of plants even on poor soils, its easy growing, low requirements for water and fertilizer make cape goosebery as attractive crop (McCain, 1993). Christov (2010) pointed out that the perspectives for the production and marketing of cape gooseberry increased in recent decades. According to him varieties as a product of purposefully breeding are very few and widely
