In PMCs of hybrids from crosses between S. nigrum X S. nodiflorum the following meiotic irregularities were observed: (1) low frequencies of trivalents and quadrivalents, (2) high frequencies of univalents and (3) bridges with or without fragments. These hybrids were highly sterile and did not set seed.
