“…Many wild relatives of legume including wild soybean and perennial wild soybean have vine stems. In common bean, vine growth habit (VGH) has three forms viz., Type I (determinate bush), Type II (indeterminate upright), and Type III (indeterminate vine) 6 , indicating the importance of both stem termination type and twining degree for VGH.…”

Vine growth habit (VGH) is a beneficial phenotype in many wild plants, and is considered an important domesticated-related trait in soybean. However, its genetic basis remains largely unclear. Hence, in the present study we used an integrated strategy combining linkage mapping and population genome diversity analyses to reveal the genetics of VGH in soybean. In this regard, two recombinant inbred line (RIL) populations derived by crossing a common wild soybean genotype (PI342618B) with two cultivated lines viz ., NN 86-4 and NN 493-1 were used to map quantitative trait loci (QTL) for VGH. Here, we identified seven and five QTLs at flowering stage (R1) and maturity stage (R8), respectively, and among them qVGH-18-1 , qVGH-18-2 , qVGH-19-3 , qVGH-19-4 were identified as major loci ( R 2 > 10% and detection time ≥2). However, qVGH-18-2 was considered as a main QTL for VGH being consistently identified in both RIL populations as well as all growth stages and cropping years. Out of all the annotated genes within qVGH-18-2 , Glyma18g06870 was identified as the candidate gene and named as VGH1 , which was a gibberellin oxidase (GAox) belongs to 2-oxoglutarate-dependent dioxygenase (2- ODD). Interestingly, there was one member of 2-ODD/GAox in qVGH-18-1 and qVGH-19-4 named as VGH2 and VGH3 , respectively. Moreover, from sequencing data analysis VGH1 and three other GAox genes were found significantly divergent between vine and erect soybean with F ST value larger than 0.25. Hence, GAox was assumed to play a major role in governing inheritance of VGH in soybean. Therefore, elucidating the genetic mechanism of GAox is very useful for exploring VGH and other stem traits, as well as genetic improvement of plant type in soybean.

“…Yield responses of beans from three morphologically-different, non-climbing types, grown at three spacings, have been described (Kueneman et al, 1978) for two trials at Palmira, Colombia, in 1973 and1974. This paper describes the morphological characteristics and growth rates of these beans as they varied over habit of growth and spacing, and as they related to yield.…”

Growth characteristics of dry bean genotypes of determinate (Type I), indeterminate small vine (Type II), and indeterminate large vine (Type III) types were evaluated over three spacings and two growing seasons. Important observations include: (i) Type I did not give increased yields in response to planting rows closer together in Trial II because there was a large decrease in harvest index, which did not occur for Types II and III; (2) accumulation of reproductive nodes prior to anthesis is important for high yields, as are biological yield, harvest index and leaf area; and (3) within-habit spacing combinations, factors such as flowering duration, branch-, leaf-and raceme-numbers, and stem length could not be used to predict yield.Yield responses of beans from three morphologically-different, non-climbing types, grown at three spacings, have been described for two trials at Palmira, Colombia, in 1973 and 1974. This paper describes the morphological characteristics and growth rates of these beans as they varied over habit of growth and spacing, and as they related to yield. MATERIALS AND METHODSBean varieties with Types I, II and III growth habits (determinate, indeterminate small vine and indeterminate large vine, respectively) were grown at three spacings (50 x 5, 50 x 10 and 75 x 10 cm) in three randomized complete blocks. Betweenrow spacings (50 and 75 cm) were whole-plots and combinations of growth habits (Types I, II and III) and within-row spacings (5 and 10 cm) made up the subplots of a split-plot treatment design. Each Type was represented by seven to nine genotypes in Trial I and five in Trial II. Genotypes were nested within growth habits and are listed in Table 5. All genotypes of the same habit and spacing were planted next to each other in single rows 6 m long in Trial I and in three-row 6 m long plots in Trial II.Seed and biological yields were determined by harvesting plants from two central metres of each single-row plot in Trial I and from the middle row of three-row plots in Trial II. Observations on growth analysis variables prior to final harvest, i.e. at anthesis and 20 days later, were taken from each of five consecutive plants from every experimental unit (each factorial combination of genotype, spacing and replication). This five-plant sample was removed 1 m from the end of the row that was ultimately harvested for yield determination.Analyses of variance, linear regressions and correlation analyses were computed, using the Statistical Analysis System (SAS) developed by the Department of |Present address: International Institute of Tropical Agriculture, PMB 5320, Ibadan, Nigeria. 180014-4797/79/0000-1308 S01.00

“…Nevertheless, by seed legume standards dry bean is considered an unimproved, low yielding crop (1). A major limitation to increased seed yields in this crop is its lack of responsiveness to fertilizer nitrogen; supplemental nitrogen creates predominantly vegetative structures at the expense of reproductive ones, especially in the vining bean genotypes (10). Another limitation is its low symbiotic nitrogen (N 2 ) fixation potential, which is considered about one half that of soybean (14).…”

The growth regulator 2, 3, 5 triiodobenzoic add (TIBA) was applied foliarly at the beginning of flowering (R1 stage) to a vining dry bean (Phaseolus vulgaris L.) genotype, grown symbiotically in a low nitrogen containing soil. Profiles of root nodule nitrogenase and leaf nitrate reductase activities, as well as of leaf chlorophyll content throughout the postflowering period, indicate that TIBA reduced the duration of nitrogen incorporation and caused early senescence. An increase in the number of pods per plant as well as in dry matter harvest index, supports the theory that TIBA causes bean plants to shift from vegetative to reproductive growth. No seed yield increase occurred as a result of TIBA application. Symbiotic nitrogen fixation alone may not provide sufficient nitrogen to allow optimal development of an increased number of pods. Further trials under higher soil nitrogen levels are suggested.
