Abstract: Ten genotypes of bachelor’s button (Gomphrena globosa L.) were evaluated with an aim to identify suitable varieties based on different characters under Northern Karnataka region at Horticulture farm, UAS, Raichur, during the year 2017-18. The results revealed that genotype AGS-10 recorded maximum plant height (132.17 cm), maximum plant spread (121.67 cm), number of leaves plant^Ë—1 (4140.83), leaf area plant^Ë—1 (1200.78 cm²), leaf area index (0.4447), number of primary branches plant^Ë—1 (16.53) and number of secondary branches plant^Ë—1 (106.93) were observed in the genotype AGS-1, whereas, maximum stalk length was recorded in AGS-5 (20.73 cm) genotype. Minimum plant height (40.30 cm), plant spread (44.50 cm), number of leaves plant^Ë—1 (1513.87), leaf area plant^Ë—1 (439.00), leaf area index (0.1625), number of primary branches plant^Ë—1 (10.93), number of secondary branches plant^Ë—1 (49.63), and stalk length (5.33 cm). The genotype ‘AGS-13’ took minimum number of days to flower bud initiation (9.67 days) but it was maximum in AGS-1 (14 days) whereas, days taken for 50 per cent flowering was minimum in AGS-13 (12 days) and maximum in AGS-5 (24 days) and Genotype AGS-1 flowered for a maximum period of 87.67 days and the flowering duration was minimum in genotype AGS-14 (67.67 days). The maximum flower yield (13.75 t/ha) was recorded in AGS-1 and it was lowest in AGS-14 (8.10 t/ha).
