| Popis: | This study aimed to characterize and select silk blossom genotypes (Calotropis procera) with forage potential. Between April and July 2014, we cultivated 89 genotypes in plastic tubes arranged in a randomized block design with three replications; each experimental plot was composed of 8 plants. The following characteristics were evaluated: plant height (PH), stem diameter (SD), number of leaves (NL), total leaf area (TLA), leaf fresh mass (LFM), stem fresh mass (SFM), root fresh mass (RFM), leaf dry mass (LDM), stem dry mass (SDM), and root dry mass (RDM). Significant differences (p < 0.05) among genotypes were observed for all characteristics, except for NL at 45 and 60 days after sowing (DAS) and for RFM at 60 DAS. Broad-sense heritability estimates and genotype means had medium and high values for most characteristics. Genetic variability among C. procera genotypes was observed. High gain selection was found for the characteristics TLA, PH, SFM, LFM, SDM, and LDM as the genotypes 79, 65, 48, 12, 51, 35, 63, 25, 1, and 46 are suitable for future breeding works to improve forage production. Objetivou-se caracterizar e selecionar genótipos de flor-de-seda (Calotropis procera) com potencial para forragicultura. Para tanto, 89 genótipos foram cultivados em tubetes organizados em blocos ao acaso com três repetições, no período entre abril e julho de 2014, sendo a parcela experimental composta por 8 plantas. Foram avaliadas as características: altura da planta (AP), diâmetro caulinar (DC), número de folhas (NF), área foliar total (AFT), massa verde das folhas (MVF), massa verde do caule (MVC), massa verde da raiz (MVR), massa seca das folhas (MSF), massa seca do caule (MSC) e massa seca da raiz (MSR). Houve diferença significativa (p |
