Abstract
INTRODUCTION: The Lima bean (Phaseolus lunatus) is distributed worldwide, and characterized by greater tolerance to drought, excess moisture, as well as high temperatures (VIEIRA, 1992). In Brazil, it presents a limited region of cultivation, being mainly emphasized in the northeast region of Brazil, being directly connected to the feeding of the familiar farmers. The objective of this work was to evaluate the genotypes of Lima bean from the subtropical region of Brazil.
MATERIAL AND METHODS: In the agricultural year of 2015-2016 genotypes of lima bean, which were characterized according to: DEF, day number to emergence up to 50% of plants in flowering plot, number of harvests; plant habit: semi-erect (SE) and prostrate (P); kind plant: 3- semi-erect and branched and 4-prostrate and branched; growth habit: semi-determined (SD) and Undetermined (U), postage and flower color: white (W) and yellow (Y). The experiment was conducted at the Experimental field of the Terras Baixas Station, Embrapa Clima Temperado, in the municipality of Capão do Leão, RS, at 31º48'15''S latitude and 52º24'42"W longitude. The climate classified as Cfa according to Köppen and Geiger, presenting a temperature of 18.0ºC and a rainfall of 1.378 mm. Sowing was carried out on 01/13/2016, occurring the emergence in 50% of the seedlings on 01/21/2016 The experiment consisted of two lines of each genotype, spaced 0.65 m between rows and 0.20 m between plants, with a density of 5 plants per linear meter.The experiment consisted of two lines of each genotype, spaced 0.65 m between rows and 0.20 m between plants, with a density of 5 plants per linear meter.
