Abstract
Potato onion is the one of the specific species known as a part of biocultural heritage in many countries.
The increasing interest of this germplasm causes the importance of biodiversity and productivity estimation and developing of stable cultivars suitable for the local climatic condition and growth regions.
Nine landraces and three breeding lines of potato onions were investigated out at the Institute of Horticulture, Lithuanian Research Centre for Agriculture and Forestry in 2015-2016. Bulbs of onions were planted in the first decade of May.
The obtained results showed the differences in morphobiological features, productivity and multiplication ratio between samples.
The bulb shape was observed rhomboid, broad oval, globe and the color of outer skin was an intensive yellow, brown and red.
The productivity reached from 0.97 to 1.64 kg m‑2. Bulbs formation distinguished with the highest diversity.
The number of bulbs per cluster differed from 4 to 13 in the different samples.
It was determined that numerous clusters formed smaller sized bulbs.
