“…Recurrence of secondary associations speaks of remote genetic homology of the various bivalents and constitutes strong evidence in favour of the derived nature of the chromosome complement (Kuwada 1910, Frost 1925, Crane and Darlington 1927, Darlington 1928, Buxton and Newton 1928, Lawrance 1931, Moffett 1931a, b, Dermen 1936. Thus, whatever be the true nature of the multiple associations formed during PMC meiosis of cultivated apples, there is sufficient reason to treat x=17 as a secondary base number derived from one or more of the three smaller numbers, represented in related tribes of the family.…”

“…The usefulness of pairing behaviour in unravelling the origin of polyploids is rather too well known (MOFFETT, 1931 ;ROSCOE, 1934) . In `Hazratbali-II' all metaphase plates scored possessed trivalents .…”

Received INDEX WORDSMalus pumila, apple, Hazratbali, polyploidy, intervarietal, intravarietal . SUMMARY A triploid cytotype of cv . Hazratbali (Malus pumila MILL .), was found growing in orchards of diploid trees . Morphological comparisons between the two cytotypes reveal that the triploid is more vigorous, and bears more attractive fruit . The meiotic behaviour of the two cytotypes has been described . The impact of polyploidy on quality characteristics of apple at the intravarietal level is analysed . The possible mode of origin of the triploid cytotype is discussed .

“…Not surprisingly, this publication had little impact in North America. Instead, data on pollen infertility (Standish, 1916) and polyploidy (Longley, 1924;Moffett, 1931) were obtained; gametophytic apomixis was only inferred from its occurrence in other taxa, and the patterns of variation documented in two studies by H.W. Rickett (1936Rickett ( , 1937compare fig.…”

This paper updates earlier reviews of polyploidy and reproductive biology in the Rosaceae, and does so with a focus on hybridization in relation to polyploidy and (facultative) gametophytic apomixis. Taking data mainly from tribe Maleae, it also seeks to point out evidence for a potential role for fertilization of infrequent unreduced gametes in diploid-diploid crosses in producing autopolyploids. Apomixis may originate in these autopolyploids, and spread as they cross with diploids and other polyploids.
