Abstract. Kuswantoro H, Artari R, Iswanto R, Imani H. 2020. Family structure of F5 soybeans lines derived from soybean varieties with the main differences in seed size and maturity traits. Biodiversitas 21: 2576-2585. The success of breeding programs depends on the availability of genetic resources with high genetic diversity. Genetic diversity plays a role in relationship between genotypes or within a group of genotypes. Seed size and the days to maturity are the main traits to develop a new superior variety for better seed quality and quantity. The plant materials consisted of eight F5 families originating from a combination of crossbreeding between four Korean soybean varieties (Daehwang, Daemang, Daewon, and Songhak) and two Indonesian soybean varieties (Argomulyo and Lawit). The main traits of four Korean soybean varieties are similar to each other, i.e. large seed size and early maturity. The two Indonesian soybean varieties differ on seed size and maturity. Argomulyo has a large seed size and early maturity, while Lawit has a small seed size and late maturity. Agronomic data, such as days to 50% flowering, days to maturity, days to harvesting, plant height, number of branches, number of reproductive nodes, number of filled pods, number of unfilled pods, seed yield per plant, 100 seeds weight, and seed yield per plot, were analyzed using R programs to form the groups. The grouping was based on principal component analysis. The results showed that the family structure of a cross was determined by the characteristics of the crossed genotypes. The family structures with Argomulyo as male parents were more influenced by 100 seeds weight, while the family structures with Lawit as male parents were more influenced by days to maturity. No family structure was formed with a large seed size on crossing with Lawit as the male parent. In this population, high seed yield as the main target of plant breeding was obtained on crossing of Daemang with Lawit.

Coefficient Of Variability

The F2 progenies of crosses among three soybean varieties were evaluated with their parents at Ngale Experimental Farm, Ngawi, East Java during the dry season of 2011. The experi-ment was conducted in a randomized block design with three replications. The seeds of each F2 progenies and parents were planted in two rows of 4.5 m long. Plant spacing was 40 cm x 15 cm and each hill contained one plant. Among the characters studied, seed weight per plant, number of pods per plant and days to maturity had the highest coefficient of variability with the means of 52.6%, 48.2% and 41.9%, respectively. Whereas seed size, plant height and number of reproductive nodes had moderate values of 36.9%, 35.5% and 37.4%, respectively. Number of branches and days to flowering had the lowest variability of 11.7% and 15.3%, respectively. Number of pods per plant, days to maturity, plant height and seed size had high mean estimates of heritability coupled with high genetic advance. The genetic progress of these characters that would be obtained for one generation of selection was estimated 47.2%, 45.7%, 40.9% and 40.3%, respectively. Among the agronomic characters, plant height, number of pods per plant, seed size and days to maturity had the highest coefficient of variability associated with high heritability and genetic advance. Therefore, selection for high yielding with early maturity soybean genotypes based on plant height, number of pods per plant and seed size might be possible.

AbstractThe largest group of Indians in West Malaysia are the Tamil-speaking Hindus who originate from South India, particularly from Tamilnad. According to S. Arasaratnam, not only are 80% of Indians in Malaysia Tamil speakers but a vast majority of them are also Hindus.1 It is further established that the majority of this group are members of the working class, either in the plantation or in the urban sectors. The family structures of these Tamil working-class families originate basically from the traditional Indian family structure of India. This traditional Indian family structure was maintained in the "conducive" environment of ethnic isolation, found in the plantations. Since my purpose is to study changes in the family structure, Tamil working-class families in an urban environment were selected. It is expected that some changes in family values and structures have occurred among this group of Indians in West Malaysia.

<p>Estimation of Genetic Variability and Correlation Among Early Maturity Mungbean Yield Components. Ratri T. Hapsari. Early maturity mungbean [Vigna radiata (L.) Wilczek] is very important to avoid drought stress, pest and disease attack as well as increase the index planting. The aims of this research was to estimate genetic variability and correlation. The genetic study included heritability, coefficient of genetic variability, genetic advance and correlation among yield components so that it can be used as selection criteria for early maturity mungbean. A total of 145 accessions of mungbean were tested at Muneng farm station in March-June 2010 using a randomized block design, with two replicates. Each accession was planted at 0.8 m x 4 m with spacing 40 cm x 10 cm, with two plants/hole. Fertilization was done by adding 50 kg urea, 75 kg SP36, and 75 kg KCl/ha, at the time of planting. The results showed that mungbean accesions had significant differences in all characters tested. The genetic variance value of all characters was broad with high broadsense heritability estimates, except for number of pods/ cluster and seed number/pod. Genetic advance of all characters were high, except for seed number/pod. The phenotypic correlation between 1000 seeds weight and pod length with seed yield were positive significant while plant height, flowering days, days to maturity, and number of pods per plant had negative significant correlation with its yield. Therefore, plant height, days to maturity, pod lenght, 1000 seeds weight and seed yield could be used as selection criteria based on estimating value of genetic variability, correlation with yield and economic value. There were five genotype which have index value above 20, i.e MLGV 0353, MLGV 0362, MLGV 0354, MLGV 0358, and MLGV 0351.</p><p> </p><p><strong>Abstrak</strong></p><p>Kacang hijau [Vigna radiata (L.)

Several "dormoat" lines that resemble Avena sativa L. ’Clintland’ in seed and plant morphology but having the seed dormancy of A. fatua L. were synthesized to test the hypothesis that fall-sown dormant oats that do not germinate until the following spring will yield more grain in Canada than spring-sown oats. In 1966, seed yield increases of 13 and 24% were obtained at Ottawa from 1965 fall sowings of dormant seed compared with spring sowings of non-dormant seed of the same "dormoat" lines. Greater seed size and escape from diseases because of early maturity were mainly responsible for the higher yields of the fall-sown as compared with the spring-sown plots. In spite of these encouraging results, "dormoats" will not be commercially useful until the spring emergence of fall-sown seed is greatly increased.

Abstract The current study assessed and compared the emotional intelligence of 75 high school students who grew up with different family structures. High school students between the ages of 16-18 years were randomly selected from high schools in Bucharest, Romania. The General Emotional Intelligence Scale (GEIS) was used to measure the level of their emotional intelligence. In addition, a nonverbal test consisting of 20 face photoswith different facial expressions was used to measure a specific aspect of emotional intelligence, perceiving emotions. Results revealed that family structure does not influence emotional intelligence; however, when looking at the aspect of perceiving emotions, family structure influences this aspect of emotional intelligence.

Purpose – This paper aims to determine whether family structure influences decision-making styles (DMSs) of Iranian couples. Design/methodology/approach – A self-administered mall survey was conducted to discover the family structures and DMSs of Iranian couples. Data were randomly collected from a sample of 800 spouses in four big cities of Iran. Exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and multivariate analysis of variance were used to examine proposed hypotheses. Findings – The EFA and CFA results show seven DMSs for Iranian couples. Also, the findings indicate family structure has a significant effect on DMS. In the other words, the results show a difference between DMSs of egalitarian and husband-dominated spouses. Research limitations/implications – One of the limitations of the study deals with product involvement, because consumer DMSs for each product category may vary. Also, children’s influences are not considered in this study, while gender/number of children may be particularly influential in family structure. Therefore, conclusions made from these findings may be limited to spouses with similar demographic characteristics. Originality/value – The present research identifies seven DMSs for Iranian couples. It also examines whether family structure is an effective factor for DMS of spouses.

It is well known that Dostoevsky was in part reacting to Nikolai Chernyshevsky’s theories, in particular his 1863 novel What Is to Be Done?, as he conceived Crime and Punishment. In her book Chernyshevsky and the Age of Realism: A Study in the Semiotics of Behavior (1988), Irina Paperno has shown that Chernyshevsky’s experiments with family structure are rooted in Hegelian theory as mediated by Russian thinkers in the 1840s. I examine Chernyshevsky’s novel as well as writings on the family and gender in Russian journalism of the early 1860s, especially Mikhail Larionovich Mikhailov’s articles and Apollinaria Prokofievna Suslova’s short stories in Dostoevsky’s journals Time and Epoch, to deepen our understanding of the family structures that appear in Crime and Punishment.

Seed yield in soybean is associated with other yield components. The objective of the study was to investigate the pattern of relationship between seed yield and yield components in soybean. Agronomic characters and seed yield of 147 soybean homozygous lines (HL) and 3 check cultivars (Dega 1, Detap 1, and Anjasmoro) were evaluated in Banyuwangi (East Java, Indonesia) from April to July 2018. The field experiment was conducted in a randomized complete block design with 2 replications. After threshing, the HLs were grouped into large seed size (> 14.00 g/100 seeds) and medium seed size (10 - 14 g/100 seeds). The causation and inter-relationship between yield components and seed yield were quantified using path analysis. Based on the seed size, a total of 150 HLs was grouped into 97 lines and 53 lines of large and medium seed size, respectively. The correlation analysis showed a similar pattern between groups of large and medium seed size. The seed yield in both groups was highly determined by the characters of the number of filled pods, number of nodes, number of branches, plant height, and wet biomass. The results of path analysis revealed that plant age, particularly the length of the generative phase, was an important factor affecting seed yield in large seed soybean lines. The length of the generative phase determining the soybean yield in this study can be suggested to be used as selection criteria to obtain high yielding and large seed size variety.

Early maturity, small seed size, and high seed yield are important characters of mungbean in Indonesia. The objective of the study was to determine the useful parents in mungbean crosses for early maturity, small seed size, and high seed yield varieties by estimating the genetic parameters and their inheritance. The study was conducted at the ILETRI, Malang, East Java, Indonesia, during the dry season of 2014. 20 F1 and 5 parents were evaluated using a randomized block design, repeated three times. Results of the study showed that all observed traits showed the importance of both additive and dominance gene effects. The relative value of general combining ability (GCA) was greater than specific combining ability (SCA) for number of pod clusters per plant, number of branches per plant, plant height, days to maturity, and 100-seed weight which indicated the importance of additive gene effect. The dominance gene effect occurred on number of pods and seed yield per plant. Among five parents, G3 was the best combiner for all the observed characters except pod length; therefore, G3 could be exploited for late maturity, small seed size, high number of branches and pod cluster, and high seed yield. G5 has a high GCA for 100-seed weight. G1 and G2 have good GCA for early maturity. G3 and G5 genotypes are useful as parents in mungbean breeding for small and large seed size varieties, respectively. The best combination for seed yield was G2 × G3 and G3 × G1 crosses and could be proceeded with selection for early maturity, small seed size, and high seed yield varieties.

Years, locations and planting density are significant factors that influence the agronomic performance of Sundak nonoilseed sunflower (Helianthus annuus L.) in southeastern Saskatchewan. As plant densities of sunflower were increased from 37 500 to 75 000 plants/ha at Indian Head from 1975 to 1977, achene (seed) yield and test weight increased linearly with density while percentages of roasting and dehulling seed categories decreased. Row spacings of 30–90 cm affected plant height and seed yield and size, but absolute amounts were not large. Based on 1984 prices of four seed-size categories, highest gross economic returns were favored by the higher plant densities. In a second test at Indian Head and Oxbow in 1979 and Areola in 1980, a range of plant densities from 22 900 to 76 400 plants/ha did not significantly affect seed yield or gross economic returns. However, yield and returns tended to be greatest for 50 000-60 000 plants/ha. Percentages of large seed decreased as plant population increased. Because markets generally favor the large-seed size categories and the price differentials among seed size categories tend to increase, plant densities of 40 000 to 50 000 plants/ha might better be recommended to allow for years with greater price differentials.Key words: Nonoilseed sunflower, Helianthus annuus L., plant density, row spacing, seed size, economic returns
