Online Published on 4 January, 2024. Abstract A study was conducted at the Department of Horticulture, Bihar Agricultural University, Sabour, Bhagalpur, to evaluate 26 marigold (Tagetes species) genotypes, including 23 experimental lines and three controls during summer season of 2016. The experiment followed a randomized complete block design with three replications. There were highly significant differences (p<0.05) among genotypes for various growth, flowering, and yield-related traits. Among the genotypes, BRMG 113 exhibited the best performance in terms of number of flowers/plant (394.98), duration of flowering (76.80 days), flower yield (39.98 kg/ plot), and overall yield (53.31 tonnes/ha). The genotype Super Red showed the minimum number of days for appearance of first flower (48.20 days) and 50% flowering (65.73 days). On the other hand, BRMG 113 had maximum flowering duration (76.80 days), number of flowers/plant (394.98), and flower yield (1599.21 g/plant). The genotype MDU 1 recorded significantly highest number of days for appearance of first flower (95.73 days), while Pusa Arpita had shortest flowering duration (29.07 days). The genotype BRMG 113 shows promising characteristics for summer season, particularly in terms of flower yield and duration of flowering. Super Red also exhibited early flowering, which may be desirable in certain contexts. Top Keywords Morphological characters, High temperature, Summer season, Yield. Top |
