“…Seventy percent of the pods are located at the top of the main stem in fasciated soybean (Wongyai et al, 1984). The soybean fasciation trait is controlled by a single recessive gene (White, 1945;Albertsen et al, 1983;Wongyai et al, 1984;Leffel, et al, 1993;Tang and Skorupska, 1997). In both normal and fasciated subtypes of determinate-type soybeans, the fl owering duration is shorter than that in the indeterminate type (Yoshida et al, 1983;Foley et al, 1986;Saitoh et al, 1998).…”

“…A good fit for 3 : 1 ratio was observed for normal and fasciated plant in all the five crosses (Table 3) ciation was also reported to be recessive and monogenically controlled in pea (Scheibe 1954), pigeonpea (Bhatnagar et al 1967, Sinha et al 1976, chickpea (Knights 1993), soybean (Albertsen et al 1983) and lintil (Tyagi and Gupta 1991). However, Lamprecent (1952) suggested that two genes control stem fasciation in pea.…”

“…Such agronomically inferior yields have been reported in the spontaneous fasciated mutants of chickpea (Knights 1993), pigeonpea (Bhatnagar et al 1967, Sinha et al 1976) and mungbean (Singh 1981) and in induced fasciated mutants of chickpea (Gaur and Gour 1999) and all these mutants were also late in maturity. The number of seeds per fruit and seed size both in the fasciated mutant and the corresponding normal plant of soybean was found to be more or less similar, although the mutant flowered late (Albertsen et al 1983). Neverthless, agronomically superior yields were reported in fasciated mutants of pea (Gottschalk 1977, Gottschalk andWolff 1977) and lentil (Tyagi and Gupta 1991) possibly due to increase in the number of branches, flowers and pods per plant, higher biological yield, higher harvest index and higher seed yield per plant.…”

Cytogenetics of a Spontaneous Fasciated Stem Mutant of Chili Pepper (Capsicum annuum L.)

Summary A spontaneous fasciated mutant exhibiting broad-strap like stem with weak tall, irregular leaf arrangement, fewer branches, larger leaves and flowers which appear like a whorled "chrysanthemum" was isolated in a local cultivar of Capsicum annuum L. The mutant had delayed maturity. In general, an increase in the number, size and shape of the floral organs, except the size of the anthers was discernible in the mutant compared to those in the sibs. The mutant did display irregular meiotic behaviour of varying degrees, while meiosis was normal and regular in the sibs of the same population. The seed set was low. The fasciation was found to be governed by a single recessive gene. The fasciation has been transferred to different genetic back grounds. This is the first report on fasciated stem mutation in members of the chili pepper.

“…In the present study, biomass partitioning has been examined in a fasciated stem soybean, Shakujo, in which the architecture is modified to shift the spatial locations of the sources and sinks, although this genotype has not been intensively studied in terms of biomass and grain production (Albertsen et al, 1983). It seems that the peculiar architecture of the genotype precludes mutual shading under constraints of population density stress and is congenial for easy flow of assimilates to sink from the source, in comparison with common cultivars of Japan.…”

This study addresses the hypothesis that stagnation of soybean yield on the farm can be improved by selection of a physiological trait favoring carbon assimilate partitioning to terminally placed pods versus genotypes having axillary pods at close plant spacing.13 C was fed to source-sink units comprising a leaf, axillary/terminal pods, and petioles at upper and lower positions of the stem axis in two soybean cultivars, namely Shakujo and Enrei, at different densities of populations. The cultivars differ significantly in architecture, Shakujo bearing a few hundreds of pods in close succession to one another in a terminally placed raceme, in contrast to Enrei having axillary racemes. Pod yield per plant was higher in Enrei than in Shakujo at low density, but Shakujo out-yielded Enrei at close spacing. Population density decreased yield per plant and altered the pattern of assimilate partitioning significantly within the plants for both varieties. At high density more assimilates moved to the upper parts at the cost of the lower parts. The terminally placed pods of Shakujo were advantaged to receive assimilates under density stress. No benefit was accrued to pod filling of Enrei, however, under this condition.
