Abstract

IN the course of investigations on species relationships within the genus Avena, a number of pentaploid hybrids derived from the cross Avena abyssinica Hochst. (2n = 28) × A. sativa L. (Black Mesdag) (2n = 42) were successfully treated with colchicine using the capping technique1. Thirty-six seeds were obtained from the doubled sectors of the treated pentaploid. Chromosome pairing was examined in four pentaploid hybrids and five decaploid plants. Twenty cells per plant were analysed and a short account of chromosome pairing at M1 in both pentaploid and decaploid forms is given in Tables 1 and 2.
