Twenty-four diverse bean (Phaseolus vulgaris L.) lines (Malawi) derived from single plant selections from landraces were evaluated for bean rust (Uromyces appendiculatus) resistance and leaf pubescence in the greenhouse (NE). A randomized complete block design was used. Each line was inoculated on the primary leaf (35-60% leaf expansion) 7 days after planting and on the 4th trifoliolate leaf (10-20% leaf expansion) with two rust strains, D82VC74fh(Dominican Republic) and A88TI-20a (Tanzania). Rust uredinia size was recorded on the 14th day after inoculation. Three lines, `Nasaka', 16-6, and `Kamtsilo' had specific resistance (SR) to one or the other of the strains but none to both strains. Many lines were susceptible on the primary leaves but had moderate to highly resistant reactions on the 4th trifoliolate leaves indicating adult plant resistance (APR). APR was the main type of rust resistance for most of these 24 lines. Many of these APR lines were glabrous. No association was observed between APR and pubescence.

An association between abaxial leaf pubescence (ALP) and adult plant resistance (APR) on trifoliolate leaves was reported previously. Recombinant inbred (RI) lines from crosses PC-50 (P1) with XAN-159 (P2) and BAC-6 (P3), and P3 with HT7719 (P4) were used to study the inheritance of specific resistance (SR), APR and ALP. P1 is resistant to A88TI-4b and has abaxial hairs on the trifoliolate leaves while P2, P3, and P4 are all susceptible (S) and have glabrous (G) leaves. P3 is resistant to D85C1-1. SR to A88TI-4b on primary leaves (PL) was determined by a single dominant gene with an additional dominant gene for APR on the 4th trifoliolate leaves in P1 × P2. ALP was governed by a single dominant gene with no association with APR. SR to A88TI-4b on PL in P1 × P3 was controlled by a single dominant gene. SR to DC85C1-1 on the PL was determined by a single dominant gene in P3 × P4.

A field experiment was conducted at the Horticulture Farm of the Department of Horticulture, Bangladesh Agricultural University, Mymensingh to investigatethe effect of mulching and plant spacing on the growth and yield of French bean during the period from November 2014 to January 2015. The experiment consisted of three types of mulchingnamely (i) control (without mulch), (ii) water hyacinth and (iii) black ploythene much and three levels of spacing viz., (i) 30 cm x 25 cm (ii) 30 cm x 20 cm and (iii) 30 cm x 15 cm. The experiment was laid out in randomized complete block design with three replications. Results showed that both mulching and plant spacing significantly influenced the growth and yield components of French bean. Black polythene mulch produced the highest yield (5.82 t/ha) and the lowest yield (4.92 t/ha) was recorded fromno mulch treatment. The maximum yield (6.22 t/ha) was obtained from 30 cm x 15 cm plant spacing and the lowest (4.58 t/ha) was obtained with 30 cm x 25 cm plant spacing. The combined effects of mulching and plant spacing were statistically significant. The combination of black polythene mulch with 30 cm x 15 cm spacing gave the highest yield (6.97 t/ha) and the lowest yield (3.94 t/ha) was received from without mulching at spacing of 30 cm x 25 cm treatment combination. Considering the above findings the black polythene mulch with 30 x 15 cm plant spacing  may be recommendfor French bean cultivation.Progressive Agriculture 26 (2): 129-135, 2015

Five trials using a randomized complete block design with four replicates were performed to determine the effectiveness of several fungicide treatments against the bean rust as well as their effect on yields. The chemicals screened were bitertanol, diclobutrazol, diniconazole, hexaconazole, iprodione, metiram, oxycarboxin, penconazole, pyracarbolid, triadimefon, triadimenol and tridemorph + maneb which were compared with sulphur, used as standard and with an untreated check plot. The best results were obtained with Bitertanol 30 EC, Hexaconazole 5 SC and Oxycarboxin 75 WP sprayed at 0.5 kg/ha on a 14 days interval. No significative differences were found among the treatments, which statistically excelled Sulphur 80 WP sprayed weekly at 3 kg/ha and raised the yields significantly inrelation with it.

Rajma (Phaseolus vulgaris L) known as the common bean, French bean, kidney bean, bush bean, and pole bean is the most important grain legume of Nepal which covers about 10,529 ha areas along with the productivity of 1477kgha-1. Generally it is grown during summer in mid/high hills and during winter (post rainy) season interai/inner terai in rice and maize based eco-system. Now Rajma bean is being popular as the cash crop in the province 3, 5 and 6 because of producing organic products and tastier quality. Multi-environment trials was carried out at Nepalgunj, Parwanipur, Itahari and Surkhet during the winter season of 2014-2017 comprised of 10 diverse Rajma genotypes in Randomized Complete Block Design with three replications in order to evaluate the quantitative variation with respect to yield and yield contributing traits. The combined analysis of variance showed that the highly significant differences among the genotypes and locations in the traits like days to flowering, days to maturity, plant height, hundred seed weight and grain yield. However; there was not any GxE interaction effect found in days to flowering, days to maturity and grain yield. Mean yield performances showed that the genotype PDR-14 (2341kgha-1) produced the highest yield followed by Utkarsh (2332kgha-1) and Arun-2 (2021kgha-1). In conclusion, PDR-14 gave 9-56% higher yield among the genotypes and its stability analysis test also indicated that PDR-14 was found a highly stable across the environments and over the years. Variegated red kidney shape seed, white flowers along with dwarf and glabrous leaf pubescence is the DUS trait of the PDR-14 and recommended for terai/inner terai to high hills.

Dry bean (Phaseolus vulgaris L.) production is limited by bean rust [Uromyces appendiculatus (Pers.) Unger var. appendiculatus]. An effective control strategy for this disease is to breed cultivars with durable resistance. Information on the inheritance, genetic relationships, and mapping of genes with molecular markers for specific resistance (SR), adult plant resistance (APR), and abaxial leaf pubescence (ALP) is needed to pyramid the desired genes for durable resistance. ALP was found to be associated previously with APR in Andean germplasm. The objective here was to identify and map RAPD markers for the genes controlling SR, APR, and ALP and to examine their relationships. Five rust pathotypes were inoculated on the unifoliate leaves of 68 recombinant inbred (RI) lines derived from `PC-50' (presence of SR, APR, and ALP) × XAN-159 (absence of SR, APR, and ALP). SR was determined by a single major gene (Ur-9) to the five rust pathotypes with no detection of recombinants. The fourth trifoliolate leaves were inoculated with one pathotype (A88T1-4b). A single major gene Ur-12 controlled APR to that pathotype. The Ur-9 gene (SR) was independent of and epistatic to the Ur-12 gene (APR). Because of the low number of APR lines in the RI population resulting from the elimination of RI lines with SR, an F2 population was developed from a cross of two homozygous RI lines selected for unifoliate susceptibility to pathotype A88T1-4b and for resistance and susceptibility of the fourth trifoliolate leaves to tag RAPD markers linked to the Ur-12 gene (APR). The single major gene Pu-a determinated ALP and was not linked to Ur-9 (SR) and Ur-12 (ALP). The gene Ur-9 (SR) was linked to RAPD marker J13-1100 at 5 cM and was not assigned to any linkage group or other markers. The gene Pu-a (ALP) was mapped at 20.2 cM from 116.500 and 3.9 cM from marker G3.1150 in linkage group 3. The Ur-12 gene (APR) was mapped at 34.6 cM from marker O13.1350 in linkage group 4b. This is the first report of mapping a gene for APR in common bean.

Westermann, D. T., Terán, H., Muñoz-Perea, C. G. and Singh, S. P. 2011. Plant and seed nutrient uptake in common bean in seven organic and conventional production systems. Can. J. Plant Sci. 91: 1089–1099. Knowledge of plant and seed nutrient uptake by crop cultivars in organic and conventional production systems (PS) is essential for breeding the most appropriate genotypes for each PS. The objective was to determine the plant and seed uptake of nitrogen (N), phosphorus (P), potassium (K), copper (Cu), manganese (Mn), and zinc (Zn) by 16 common bean genotypes. We also identified genotypes efficient in plant and seed nutrient uptake across seven organic and conventional PS. A randomized complete block design with four replicates (one plot per replicate) was used for evaluation in each of seven organic and conventional PS in 2003 and 2004. The effects of plant and seed uptake of nutrients, genotypes, PS, and the genotype × PS interaction were significant (P≤0.05). Plant and seed uptake of nutrients decreased in on-station continual dry bean and drought-stressed and on-farm organic low-input compared with on-station conventional irrigated and on-farm organic high-input PS. Common bean genotypes with higher biomass yield, in general, also had higher nutrient uptake, regardless of PS. In general, N and P uptakes were high and that for Mn was markedly low among common bean genotypes. Pinto CO46348, Bill Z, and Othello and Mexican red NW-63 and UI 239 were high-yielding and used nutrients more efficiently across seven organic and conventional PS and years. Other cultivars either had low biomass and seed yield (e.g., Common Pinto, Topaz, Common Red Mexican, UI 59) or were more efficient at whole-plant uptake or seed uptake of nutrients, but not both (e.g., Matterhorn, UI 465). Use of the above five genotypes should be maximized for production in both organic and conventional PS, and for breeding high-yielding broadly adapted cultivars efficient in plant and seed nutrient uptake in organic and conventional PS.

An experiment with 45 Theobroma cacao L. clones grafted onto a common rootstock was established between September 1991 and November 1997 to determine the yield potential of trees selected from interclonal families. Scionwood of 40 promising trees selected from among 1,320 trees, representing five families and three locations "m Puerto Rico, were patch bud grafted onto the rootstock clone EET-400. Additionally, scionwood of five of the eight parental clones involved in the combination of the families was also grafted onto the same rootstock. The 45 treatments were arranged in a randomized complete block design with six replications, each containing two experimental trees per replication. The trees reached full production in 1994, during the third growing year. Between 1994 and 1997 the mature pods were harvested, and the dry bean weight and pod index were determined. The means of the 40 grafted selections were compared with the combined means of five parental clones or to the mean of their highest yielding parent (P < 0.01). At the termination of the experiment in November 1997, only nine of the grafted clones significantly outyielded their parents, with a mean production of 2,170 kg/ha/year of dry beans. This finding indicated that fewer than 1% of the trees in the original five-family population were exceptionally superior yielders. Five of the nine superior yielding clones also had a significantly higher pod index. None of the 16 clones representing families IMC-67 X SCA-12 and IMC-67 x UF-613 performed as superior yielders. We concluded that either one or both parents involved in these interclonal crosses lack combining ability and may be excluded from cacao improvement programs, in addition, we found a direct relation between high pod index and superior dry bean weight in the progeny of family SCA-6 x EET-62.

This study was designed to compare snap and dry beans (Phaseolus vulgaris L.) for pod Ca concentration, and to identify genetic resources that might be useful in breeding programs directed to increase Ca concentration in bean pods. Pods from eight snap bean and eight dry bean cultivars were evaluated for Ca concentration during 1995 and 1996 at Hancock, Wis. A randomized complete-block design was utilized with three replications in 1995 and six in 1996. Beans were planted in June and hand-harvested in August for both experiments. Soil Ca at planting time was 580 mg·kg–1 in 1995 and 500 mg·kg–1 in 1996. No additional Ca was added. Plots consisted of 10 plants each. At harvest, a pooled sample of 10 to 15 size no. 4 pods was collected from each plot. Atomic absorption spectrophotometry was used to determine Ca content. Significant differences (P ≤ 0.01) were detected among and within bean types (dry and snap). Although bean type × year interaction was nonsignificant, a strong year effect was observed (P ≤ 0.01). Snap beans (4.6 ± 0.7 mg·g–1 dry weight) had significantly higher pod Ca concentration than did dry beans (4.2 ± 0.6 mg·g–1 dry weight). Within snap beans, `Checkmate' had the highest pod Ca concentration (5.5 ± 0.3 mg·g–1 dry weight) and `Nelson' the lowest (3.8 ± 0.3 mg·g–1 dry weight). Within dry beans, `GO122' had the highest (5.1 ± 0.4 mg·g–1 dry weight) and `Porrillo 70' the lowest pod Ca concentration (3.6 ± 0.3 mg·g–1 dry weight). Six cultivars had pod Ca concentrations significantly (P ≤ 0.01) higher than the overall mean (4.4 ± 0.3 mg·g–1 dry weight).

Sixteen Alubia lines (15 with long, straight hairs and one with short, hooked hairs on trifoliolate leaves) derived from single-plant selections made in an Alubia landrace (Argentine) were used to evaluate the relation of abaxial leaf pubescence to reaction to rust in a greenhouse experiment. The pinto cultivar UI-114 (short, hooked hairs) was used as a susceptible check. One plant per pot, replicated six times, in a randomized complete-block design was used. The primary leaves and the sixth trifoliolates of all plants from 12- and 50-day-old plants, respectively, were inoculated with a water suspension of urediniospores (105 cells/ml) of rust isolate US-NP85-10-1. Pustule size and rust intensity were assessed 14 days later. No rust pustules were observed on the sixth trifoliolate leaves of the pubescent (long, straight hairs) Alubia lines, but large pustules were observed on the primary leaves (short, hooked hairs) of all Alubia lines and pinto `UI-114'. as well as on the sixth trifoliolate leaf of A-07-2 and pinto `UI-144' (the latter two with short, hooked hairs).

An experiment laid in a Randomized Complete Block Design with 4 blocks and 5 treatments, was done at Kutsaga Research Station in the 2012 / 2013 season to study the impact of time of weeding on tobacco production. The treatments comprised of different times of weed control with a weed free treatment as the control. The variables measured were stalk heights at 5, 6 and 7 weeks after planting and, leaf expansion measurements were also recorded at 9, 10 and 11 weeks. Leaf yield was measured at untying using a digital scale. Results showed that Tobacco stalk heights were affected at 5 W.A.P since significant differences (P<0.05) were noted among the treatments. Suppressive effects of weeds were shown at 6 and 7 W.A.P due to effective competition (RCI > 0) in all other treatments excluding the control. There were significant differences (P<0.05) among the treatments on leaf expansion at 9, 10 and 11 W.A.P. The treatment weeded at 4 W.A.P showed leaf yield that was significantly higher (L.S.S = 270.8) than the treatment weeded at 2 W.A.P. Basing on the 3 reaps recorded, time of weeding had an influence tobacco yield.
