Performance of Broccoli Genotypes With Respect to Morphological, Phenological, Head and Yield Traits at Three Localities of Nepal.

Abstract

Broccoli (Brassica oleraceae var. Italica) belongs to the family cruciferae which is mainly used as vegetable at its tender stage. The study was conducted to evaluate the morphological, phenological, head and yield traits of broccoli genotypes at Karma Innovative Research and Development Stations of Kathmandu, Kavre and Kaski district of Nepal from September 2019 to March 2020. The experiment was laid out on Randomized Complete Block Design with four replications at each location. Genotypes, location and interaction between them showed significant variation on almost all parameters. BL-17001, BL-18012 and Centauro genotypes were observed with no lateral heads, which means low yield than other varieties. BL-16003 was observed with maximum yield (1.0 kg/plant at Kathmandu and kavre and 0.9 kg/plant at Kaski) at all locations comparing to other genotypes. Among high-yielding genotypes (BL-16003 and BL-18009) BL-16003 found as early maturing and also had lateral heads so, it can also be used for multi-harvesting. In addition, the height of this genotype was in the lower range with highest number of leaves. Thus, BL-16003 is found as the promising genotype at all localities.
