Abstract:
The bean plant is a legume plant that binds free nitrogen of the air by the nodosity formed in the roots. For this reason, it was aimed to investigate the effect the pod of bean characteristics of bean by applying different doses of phosphorus and nitrogen on Göksun beans cultivar. In the study, 0, 3, 6, 9 kg da-1 phosphorus and 0, 4, 8, 12 kg da-1 nitrogen doses were applied to Göksun bean variety. The pod length (cm), pod width (mm), pod diameter (mm), number of pods per plant (edet), weight of a single pod (g), number of seeds per pod (pieces), weight of single seeds (g) of Göksun bean cultivar were investigated. In the research, it was noted that the effect of phosphorus doses only on the pod diameter, the effects of nitrogen doses on the pod length, pod diameter, pod width, single seed weight and seed number of pod were significant. The differences in number of pods in the plant, seed number of pods, pod length, pod weight, single seed weight in terms of phosphorus and nitrogen interaction were founded statistically significant. According to the results of the research, it was determined that 4 kg da-1 and above nitrogen dose applications made a positive contribution in terms of pod propertiesKeywords:

The genotypic and phenotypic correlations of green pod yield with different components were estimated from 20 genotypes of vegetable cowpea pooled over two seasons. The genotypic and phenotypic correlations agreed closely with each other. Pod length, green pod weight, dry pod weight, seeds per pod and 100 seed weight exhibited significantly positive correlations with green pod yield. Their genotypic correlations with green pod yield were also high and positive. Days to flowering, on the otherhand, registered high and negative association with green pod yield both at phenotypic and genotypic levles. A few significantly positive interrelationship were found between the different components. Pod number, on the contrary, exhibited significantly negative interrelationships with green pod weight and pod length. The path coefficient analysis of green pod yield showed that green pod weight, dry pod weight, pod number and seeds per pod were the most important components because of highly positive direct effects. Days to flowering registered highly negative direct effect indicating early flowering would lead to high yield. Therefore, green pod weight, dry pod weight, pod number, seeds per pod and days to flowering were the important components for improving pod yield in vegetable cowpea.

Oxalate had no direct effects on the POD activity, but it could induce the increment of the POD activity in the local leaves and in the systemic leaves of cucumber seedlings. The increment of POD activity in the different parts of cucumber is related to the form of POD and the time after treatment .

Selection for seed weight among soybean [ Glycine max (L.) Merr.] genotypes can be accomplished by indirect selection for width of mature pods. Our study was designed to evaluate additional variables that could influence the effectiveness of indirect selection for seed weight. The objectives were to determine the influence of number of seeds per pod on pod length, width, and thickness; to determine if measurements on full‐size green pods were as effective for selection as measurements on mature pods; and to determine which pod dimensions would be most effective for indirect selection. Data were obtained on F 4 plants and their progeny from six populations in three Iowa environments. Number of seeds per pod had a significant effect on pod length, but was of no practical importance on pod width or thickness. Selection for pod length or width based on measurements of full‐size green pods was as effective as selection based on mature pod dimensions. Selection for pod length or width was more effective than for pod thickness. Use of pod length or width alone was as effective for selection as evaluation for pod area or volume. Pod width was considered the most efficient character to use for indirect selection because it can be measured without regard to number of seeds per pod and is faster to measure than pod length.

Pod shattering is one of the major soybean constraints in the soybean production centers, particularly in the tropics. The screening for pod shattering resistance of 16 genotypes was carried out using detached and undetached pod methods on the three different pod positions on the stem. The field research was arranged in a randomized block design, during the dry season in Banyuwangi, Indonesia. The shattering evaluation was conducted in the laboratory using the ovendry method. The screening methods to investigate the pod shattering resistance of each genotype consisted of the detached pod (DP), undetached pod (UDP), and undetached whole-stem method (UWS). The result showed that the detached pod method (DP) resulted in a higher average podshattering percentage (15%) than the undetached pod methods (UDP and UWS, 13% and 11%, respectively). Nevertheless, the detached pod and undetached pod methods provide a consistent result for the evaluation of pod shattering resistance, showed by their correlation coefficients (DP and UDP, r = 0.98**; DP and UWS, r = 0.98**, UDP and UWS, r = 0.99**). The detached pod with the oven-dry method was suggested to be used for screening of pod shattering resistance. This method enables to screen genotypes in greater numbers, provides a homogeneous selection pressure and environmental condition. Pods at the upper part of the stem were more resistant to shattering than those pods in the middle part and lower part. The pod length, seed length, seed weight, pod wall weight to the pod weight ratio, and weight of 25 seeds appeared to be the significant indicators for pod shattering resistance. The shattering evaluation resulted in five soybean genotypes (Anj/G100H-28, Anj/G100H-44, Anj/Rjbs-304, Anj/Rjbs-30, and Detap 1) with consistent resistance to pod shattering based on the three methods. These genotypes can be used as donor parents in the breeding program for pod shattering resistance.

Fourteen winter-sown genotypes of Lupinus angustifolius L., comprising most of the Western Australian cultivars released since 1986, were studied over 2 years at 4 southern Chile locations. Pod wall proportion, pod wall specific weight, seed number per pod, mean seed weight, seed weight per pod, wall weight per pod, and mean pod weight were measured, separately sampling pods from the mainstem and pods from branches. The 2 pod positions differed significantly for all characteristics except wall weight per pod. Lower coefficients of variation and greater heritabilities for both pod wall proportion and pod wall specific weight were achieved with a sample of pods from branches than with a sample from the mainstem.The ranges for pod wall proportion and pod wall specific weight were small (31.8–35.8% and 27.0–34.7 mg/cm2, respectively); however, highly significant genotypic effects were found for both characters. Heritability estimates were moderate for pod wall proportion (0.27 and 0.44 for pods from mainstem and branches, respectively) and moderate to high for pod wall specific weight (0.56 and 0.61, respectively).Pod wall proportion and pod wall specific weight were significantly correlated, more so at the genetic level (rg�=�0.83 and rg = 0.76 for pods from mainstem and branches, respectively) than at the phenotypic level (rph = 0.57 and rph = 0.60, respectively). Pod wall specific weight was closely associated with wall weight per pod, meaning that larger pods call for thicker pod walls. Accordingly, selection for low pod wall specific weight in a breeding program could lead to light pods. Correlations with mean seed weight indicate that this trait could decrease as well.
