The results of estimation of growth and development parameters, SSR analysis, electron microscopic examination of the surface of pollen and seeds, biochemical composition (ascorbic acid, carotenoids, carotenes, macro- and microelements content in the stem part of plant) of 8 Chinese broccoli, Brassica oleracea var. alboglabra samples grown in the unheated greenhouse of the Central Siberian Botanical Garden SB RAS, Novosibirsk (54°49'33" N, 83°06'34" E) and phytotron of N. I. Vavilov Institute of Plant Genetic Resources (VIR) have been presented. Through the study, the large surface cellularity of B.oleracea var. alboglabra (cv. "Siji Xianggu jie lan’ [“SX’]) seeds was similar with seed coat surface of B.oleraceae var. capitata f. alba cv. "Slava“. A scanning electron microscopic study of Chinese broccoli pollen (cv. “SX") revealed the formation of colpate pollen with ellipsoidal shape with a size of 32.9 ± 0.76 x 17.8 ± 0.42 pm, characterized by foveolate ornamentation with a length-to-diameter ratio - 1.85.The duration of the period from emergence stage to thickening of a stalk and flower-bud formation ofcv. "SX’ continued for 49-54 days. dose correlation was established between the largest diameter of the stem and the length of the leaf petiole (r=0,87, p
