Background: Pod shattering has become the major problem in soybean production. The research aims to identify the pod shattering resistance and to assess the agronomic performances of 50 soybean genotypes and the association among agronomic characters. Methods: The research materials were 50 soybean genotypes which consisted of 47 lines derived from routine crossing programs and three check cultivars. The field experiment was arranged in a randomized block design with two replications. The data were observed for yield and its component traits. The oven-dry method was performed in the laboratory to assess the pod shattering resistance. Result: Variation among genotypes was found in the pod shattering resistance and agronomic characters. The genotype by trait biplot graph showed that pod shattering was negatively correlated with the days to maturity and plant height, but positively correlated with the seed size. Soybean genotypes of Grob/G100H-1-588 and G100H/Mhmr-4-993 were resistant to pod shattering and have a high seed weight per plant. These genotypes were potential for further varietal development or could be used as gene sources in the soybean improvement program for pod shattering resistance.

Seven parents (CST2002, MT34, OS-Sel-2, TKG22, AAUDT9304-14-4, B67 and Rama), their 21 F 1 s and 21 F 2 s were grown in summer 2003 in a randomized block design with three replications. Heterosis and inbreeding depression were studied for seven important yield-contributing characters (plant height, branch number plant −1 , capsules plant −1 , seeds capsule −1 , 1000-seed weight, stick yield plant −1 and seed yield plant −1 ). Maximum heterosis for seed yield plant −1 over the mid- and better-parent was recorded in CST2002×TKG22 (43.30%) and MT34×B67 (27.22%), respectively. Mid-parent heterosis for seed yield plant −1 was due to cumulative heterosis for various important component traits, such as capsules plant −1 , seeds capsule −1 and 1000-seed weight. Inbreeding depression was highest for seed yield, followed by 1000-seed weight, capsules plant −1 , branch number and plant height, indicating the predominance of non-additive genetic effects. B67×Rama exhibited significant positive heterosis in F 1 , but non-significant inbreeding depression in F 2 for seed yield. This cross can be utilized as basic material for identifying better pure lines. The clustering pattern indicated that in general genetically diverse parents exhibited more heterosis, as evident in the majority of the crosses.

<p>This research was aimed to identify shade-tolerant soybean genotypes that was suitable for planting under rubber tree plantation. The research was conducted at three locations of rubber tree plantation in Central and East Lampung where the rubber tree were at age of 3 to 4 years, during dry season of 2011. The materials consisted of 30 soybean genotypes, where 23 lines were shadetolerant, and seven were as check varieties (Pangrango, Burangrang, Malabar, Argomulyo, Grobogan, Ijen, and Tanggamus). Each genotype was planted in plot of 4 m x 2.2 m, plant spacing was 40 cm x 15 cm, two plants /hill. The experiment used a randomized block design, repeated four times. Before planting, dolomite of 1.5 t/ha was applied, and 75 kg Urea / ha + 100 SP36 kg/ha + 100 kg KCl /ha was applied at planting time. Observations were done on flowering date, harvesting date, plant height, number of branches, number of reproductive nodes, number of pods, seed weight per plant and grain yield. The light intensity under the rubber tree canopy was observed every week after the soybean age was 30 days (DAP), at 11:00 to 12:00 pm. The levels of shade made by the rubber tree canopy at three locations were different; at Tulangbalak (East Lampung) and Gunungsari (Central Lampung) ranged between 20% to 40%, at Gunungadi (Central Lampung) between 40% to 60%. Genotypes IBM22-861-2-22-3-1 and AI26-1114-8-28-1-2 yielded consistently well in two locations, in East Lampung (1.40 t/ha and 1.43 t/ha), in Central Lampung (1.19 t/ha and 1.18 t/ha). Genotype IBM22-861-2-22-3-1 and AI26-1114-8-28-1-2 produced the highest average yield out of the three locations, i.e 1.13 t/ha. Genotype IBM22-861-2-22-3-1 and AI26-1114-8-28-1-2 were considered as suitable genotypes for planting under the rubber tree of 3 to 4 years of age.</p>

Research was aimed to evaluate  performance of new genotypes of soybean selected in shaded environment under rubber stands and compare it with superior soybean varieties. Field experiment was arranged in a simple Randomized Block Design. Treatments comprised five levels namely four soybean genotypes selected in artificial shade and one shade tolerant superior soybean variety as a check. Each treatment was replicated 5 times. Experimental unit was a plot with size 3 m x 2 m  with 100 plant population. Ten plants were used as samples. Observations were made on growth and yield variables. Such variables were plant height, number of branches, and stem diameter, while the observed yield variables included number of pod per plant, 100 seed weight, and seed weight of 10 plants. Observed data were analyzed by Analysis of Variance and continued by Duncan Multiple Range Test at α 5% level to compare the tested genotypes. Results showed that all the tested soybean genotypes gave the same performance with superior varieties of Anjasmoro in terms of stem diameter, number of branches, number of pods per plant, weight of 100 seeds, and seed weight of 10 stems of the plant. The difference was seen in of plant height where the selection genotypes were significantly shorter than  Anjasmoro Variety.

Abstract. Krisnawati A, Adie MM. 2021. Agronomic performance and pod shattering resistance of soybean genotypes with various pod and seed colors. Biodiversitas 22: 474-481. Climate change impacts agricultural production, including the increase of the yield loss in soybean due to pod shattering. This research aimed to identify the pod shattering resistance and agronomic performance of several soybean genotypes with various pod and seed colors. A total of 100 soybean genotypes were planted in Malang (East Java, Indonesia) during the dry season 2019. The field experiment was laid out in a randomized block design with three replications. The pod shattering resistance was assessed using the oven-dry method. The pod shattering resistance of 97 genotypes were classified into 20 very resistant genotypes, 17 resistant genotypes, 15 moderate genotypes, nine susceptible, and 36 very susceptible genotypes. The pod colors did not affect the pod shattering resistance in soybean. The new findings from this study, i.e., two very resistant genotypes (G42 and G15) which produce high yield and have medium maturity, were suggested to be developed as new cultivars, meanwhile, the other very resistant genotypes can be used in the soybean breeding program to develop shattering resistant cultivar with desirable traits.

Twenty three pigeonpea genotypes were evaluated in a randomized block design during Kharif 2012-13. The objective of this research was to assess inter-relationships, direct and indirect effects among yield and its components for genetic improvement of pigeonpea. The analysis of variance revealed highly significant differences for all characters under study among the genotypes. Considering the correlation analysis biological yield/plant, pods/plant, 100-seed weight, harvest-index and secondary branches/plant had highly significant positive correlation with seed yield. Path analysis identified biological yield/plant followed by harvest-index, pods/plant, days to maturity, primary branches/plant 100-seed weight and seeds/pod as most important direct yield components while biological yield/plant and harvest-index as most important indirect components. Hence, these traits should be given much emphasis at the time of devising selection strategy to achieve a quantum jump in pigeonpea yield.

Background: One of the major constraints of soybean production in Indonesia is pod shattering which occurs after soybean pod maturity. This study aimed to identify the pod shattering resistance of different pod positions in the plant stem. Methods: Sixteen genotypes were evaluated in the field research during the dry season 2019. The experiment was laid out in a randomized block design with three replicates. Ten sample plants were randomly taken after R8 phase. Plant was divided into three parts, i.e. upper part, middle part and lower part. The shattering evaluation was done using the oven-dry method in the laboratory. The observation on the number of shattered pods was measured for each part of plant stem. Result: Pod shattering was different among the pod positions as well as among genotypes. One genotype was categorized as resistant, eight genotypes were moderate, six genotypes were susceptible and one genotype was highly susceptible. The highest percentage of the shattered pods was in the lower part of the plant stem, followed by the middle and upper part, respectively. The resistant genotypes showed the shattered pods mostly in the lower part of the stem, the moderate genotypes showed the shattered pods mostly in the lower and middle part of the stem and the susceptible genotypes shattered in all part of the stem.

In Indonesia, soybean is mostly cultivated in lowland following the yearly planting pattern of paddy – paddy – soybean under zero-tillage condition. The research aim was to evaluate the agronomic performance of several soybean genotypes in lowland paddy fields under zero-tillage condition. A total of 12 soybean genotypes, including the check varieties of Wilis and Anjasmoro, were evaluated in lowland after rice planting in three locations (Klaten, Pasuruan, and Tabanan). A randomized block design with four replications was used in each location. The soybean yield is a complex character which determined by interrelated agronomic characters. The averages seed yield in Klaten, Pasuruan, and Tabanan were 2.97 t/ha, 3.02 t/ha, and 2.68 t/ha, respectively. Two genotypes produced equal yield with Anjasmoro, i.e. AT12-1062 (3.01 t/ha) and AT12-1037 (3.0 t/ha). Anjasmoro variety had the highest 100 seed weight (15.40 g), and only AT12-1035 showed the equal seed weight. The average days to maturity of 12 genotypes was 83 days. In addition to Anjasmoro variety, soybean genotypes AT12-1062 and AT12-1037 (medium maturity and medium seed size) as the new findings form this study were potential to be developed at lowland paddy fields under zero-tillage condition. The availability of the soybean genotypes adaptive to lowland paddy field under zero tillage condition is important to optimize the soybean productivity as well as the income of farmers in Indonesia.

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.
