“…Seed weight has been found to be positively correlated with cell size of different tissues (White and Gonzalez, 1990). Quantitative inheritance patterns of seed weight were reported by several investigators (Coyne, 1968;Motto et al, 1978;Nienhuis and Singh, 1988;Sax, 1923;Vallejos and Chase, 1991;Yarnell, 1965). Quantitative inheritance patterns of some determinants of bean seed shape such as seed length, seed width, and seed height were reported by Vallejos and Chase (1991).…”

Our objective was to identify quantitative trait loci (QTL) for seed weight, length, and height segregating in a recombinant inbred line population derived from the common bean (Phaseolus vulgaris L.) cross `PC-50' × XAN-159. The parents and progeny were grown in two separate greenhouse experiments in Nebraska, and in field plots in the Dominican Republic and Wisconsin. Data analysis was done for individual environments separately and on the mean over all environments. A simple linear regression analysis of all data indicated that most QTL appeared to be detected in the mean environment. Based on these results, composite interval mapping (CIM) analysis was applied to the means over environments. For seed weight, strong evidence was indicated for five QTL on common bean linkage groups (LGs) 3, 4, 6, 7, and 8. Multiple regression analysis (MRA) indicated that these QTL explained 44% of the phenotypic variation for the trait. Weaker evidence was found for three additional candidate QTL on bean LGs 4, 5, and 8. All eight markers associated with these QTL were significant in a MRA where the full model explained 63% of the variation among seed weight means. For seed length, CIM results indicated strong evidence for three QTL on LG 8 and one on LG 2. Three additional putative QTL were detected on LGs 3, 4, and 11. The markers associated with the three seed length QTL on LG 8, and the QTL on LGs 2 and 11 were significant in a MRA with the full model explaining 48% of the variation among seed length means. For seed height, three QTL on LGs 4, 6, and 11 explained 36% of the phenotypic variation for trait means. Four of the seven QTL for seed length and two of three QTL for seed height also appeared to correspond to QTL for seed weight. Four QTL for common bacterial blight resistance [Xanthomonas campestris pv. phaseoli (Smith Dye)] and for smaller seed size were associated on LGs 6, 7, and 8. The implications of these findings for breeders is discussed.

“…Interspecific relationships within the genus have been investigated using morphological characters (Trouard-Riolle, 1914, 1920Sinskaia, 1931 ;Werth, 1937), cytological examination (Yarnell, 1956;Harberd, 1972), and analysis of meiotic chromosome associations in artificial interspecific hybrids (Panetsos & Baker, 1967;Harberd & McArthur, 1972). All the taxa of the genus which have been examined so far are at least 40"L seed and pollen cross-fertile (Harberd & Kay, 1975;Kay, pers.…”

Genetic divergence in four species of the genus Raphanus: Implications for the ancestry of the domestic radish R. sativus

Four species of radish of the genus Raphanus were examined by electrophoresis ofwater soluble proteins. This technique was used to provide information about the degree of genetic differentiation of the species over a range of gene loci coding for various enzymes. These results give genetic distance estimates showing all four radish species to be closely related. From this data a simple dendrogram is constructed to show the possible interrelationships and evolutionary divergence of these species. The domestic radish Ruphanus sutivuc shows the greatest genetic similarity when compared with an Italian population of R. lundra.

“…The cytological relationships of the crop forms of the genus Brassica were elucidated in the 1930's and more recent work has not necessitated much change in interpretation (see Yarnell, 1956, for a review of the group). By contrast the wild species have received very little attention; and this situation needs rectifying both for its academic interest and because forward-looking plant breeders, turning to wild materials in order to expand their genetic resources, will need guidance from experimental taxonomy in the handling of those materials.…”

Chromosome numbers of flowering plants (Bolkhovskikh et al, 1969 Extensive genetical studies of hybrids between forms of this species have been reported (Malinowski, 1929;Magruder, 1937;Yarnell, 1956) Nearly all of the species in this closely related group-the "sea cabbages"have at some time been regarded as subspecies of B. oleracea. Several of them however have characteristics quite unlike typical B. oleracea, e.g.…”

A contribution to the cyto-taxonomy of Brassica (Cruciferae) and its allies

Material of 85 species of Brassica and genera closely related to it was examined cytologically, and the chroiftosome counts are reported. These confirm records published by other workers for 42 species, two contradict earlier records, and 41 counts are believed to be new. Different species with the same chromosome number have been cross‐pollinated, and those found to be interfertile have been grouped into cytodemes. For the most part species found to be interfertile have long been regarded as closely akin, but three cases of interfertile intergeneric hybrids are reported. Altogether the material has been classified into 45 cytodemes: 35 diploids with chromosome numbers ranging from n= 7 to n= 13, and 10 derived tetraploids. This enumeration is possibly not exhaustive of the world's genomes closely related to the crop Brassicas and a list is appended of the wild species which need examination before the enumeration might be considered to be complete.
