Abstract
The experiment was conducted in the Department of Horticulture, Sam Higginbottom University of Agriculture Technology and Science, Prayagraj, during 2021-2022. The experiment was laid out in Completely Randomized Design (CRD) with 7 hybrids and each hybrid was replicated 3 times. The different hybrids used in the experiment were npy x Golden Crown x Black Hawk, Maung x Red Bracelet, Maung x Black mkmk, Black Hawk, Red Bracelet x Big Flower x Black Hawk, Bb x Black Chadda Petch, Bb(F1) x npy Golden Crown x Black Hawk. The result obtained showed that the hybrid Black Hawk showed significantly better performance in parameters like germination percentage (86 %), seed vigour index (610), seed viability (0.86), germination speed index (1.37), survival percentage (80 %), seedling height, (8.5 cm), no. of leaves per seedlings (12), estimated leaf area (4 sq.cm), stem/caudex diameter (1.56 cm) and taproot length (6.2 cm), which was par with the hybrid npy x Golden Crown x Black Hawk.
