Abstract

Abstract: The paper studied on interspecific cross between Ogura CMS Brassica campestris ssp. pekinensis and B. oleracea var. acephala. The results showed that there was serious segregation between the two parents, which could not give birth to new seeds normally. Repetitious pollination on a single stigma at bud stage overcomed interspecific obstacles effectively. Pollen tubes grew well basically. Supplement of 6-BA and NAA after pollination failed to get hybrids. Number of chromosome of F₁ was 2n = 19.

Key words: Chinese cabbage, Kale, Interspecific cross, Compatip ility, Chromosome
