“…The primary branches, on the other hand, exhibited a negative and significant correlation with fruit fresh mass, small and biggest leaf area and total biomass per plant. These findings are consistent with those reported by [ 1 , 14 ]. Plant height was also found to have a weak positive relationship with stem fresh mass, stem dry mass, leaf yield and stem yield per plant.…”

“…In the present study, the highest expected GAM was observed for the largest leaf area, smallest leaf area, fruit fresh mass, number of leaves, number of fruits per plant, leaf dry mass, number of primary branches, fruit yield, leaf chlorophyll content, days to 50% flowering and leaf fresh mass ( Table 4 ), respectively. The authors of [ 14 , 46 , 50 ] reported similar findings of high genetic advance over a mean number of leaves and other related traits. High GAM values indicate that these traits are simply inherited; the heritability is most likely due to additive gene effects and selection may be effective in early generations for these traits [ 30 , 31 , 32 ].…”

“…The observed variability is a composite of genetic and environmental effects, of which only the former is inherited. Estimates of heritability, on the other hand, do not provide an idea of the expected gain in the next generation and must be considered in conjunction with estimates of genetic advance, the change in mean value among successive generations [ 14 , 30 , 31 , 32 ].…”

“…Furthermore, traits that exhibit high heritability with moderate or low genetic advance can be improved by inter-mating the superior accessions of the segregating population developed from multiple crosses and the desirable genes can be accumulated in the lines as stated by [ 46 , 47 ]. On the other hand, an association of high heritability with high genetic advance is an indication of additive gene effects and consequently, a high genetic gain from selection would be anticipated [ 14 , 48 ].…”

Nightshades are among many underutilized and neglected African indigenous leafy vegetable (AILVs) species, and if adequately exploited, they could improve food, nutrition and income among the rural population. Morphological characterization of available accessions is key for the breeder to identify and select superior accessions as parents for utilization in breeding programs. Fifteen accessions of nightshade were evaluated for morpho-agronomic variation in an open field trial implemented in a randomized complete block design with three replicates across the two growing seasons. The accessions exhibited significant (p < 0.0001) differences in all quantitative traits. The data analysis showed that Scabrum (805.30 g/plant) followed by Ncampus (718.60 g/plant) produced the highest fresh leaf yield; for fruit fresh yield, the accession NigSN18 (1782.00 g/plant) recorded the highest, followed by ManTown (1507.90 g/plant). The accession N5547 had the tallest plants (66.83 cm), followed by accession Timbali (62.31 cm). The first four principal components (PCs) accounted for 86.82% of the total variation, which had an eigenvalue greater than 1. The cluster analysis grouped the accessions into 14 clusters based on their genetic similarity. Results of genetic studies revealed that phenotypic coefficient variation was higher than genotypic coefficient of variation for all parameters evaluated, indicating the environmental influence on the expression of these traits. Both GCV and PCV were higher for the largest leaf area, moderate to high for the remaining characters and low for leaf fresh yield per plant. High heritability coupled with genetic advance as a mean percentage (H2-70.59%, GAM-142.4%), indicating the presence of additive gene effects. Hence, selection can be employed for the improvement of this trait in nightshades. The study revealed sufficient genetic variability in the nightshade accessions, which can be exploited for crop improvement.

“…N level has been known to determine plant architecture of Solanaceae family members (Etissa et al, 2013;Bvenura and Afolayan, 2014;Gokavi et al, 2014;Putriantari and Santosa, 2014). Plant architecture is important because it determines crop production (Ravi et al, 2013) and management (Sarlikioti et al, 2011;Degri, 2014) especially on weed control and easiness to harvest. Hence, the objective of this research was to determine the effect of nitrogen application on plant architecture, biomass and fruit production of S. nigrum in order to improve production in intercropping system.…”

ABSTRACT Demand on fruits of Leunca (Solanum nigrum L.) is increasing in Indonesia due to a rapid expansion of ethnic restaurants, especially Sundanese restaurants. Most fruits come from semi-intensive cultivation in intercropping system, leading to low productivity. In order to improve productivity, nitrogen experiment was carried out at field of Leuwikopo Farm of Bogor Agricultural University, Bogor-Indonesia, during rainy season from December 2013 to April 2014. Four levels of nitrogen, i.e., 0, 60, 120, and 180 kg N ha-1, were arranged in a randomized complete block design with four replicates. The results revealed that canopy architecture, dry matter and fruit production, and fruit quality were highly affected by nitrogen application. Increasing nitrogen levels increased biomass and fruit production. Plants treated with nitrogen at level of 60 kg ha-1 produced ideal height for local labor and stable weekly fruit production than other levels. Hence, N fertilizer is essential for achieving high productivity of S. nigrum.Keywords: canopy shape, fruit load, indigenous vegetable, leunca, ranti kebo ABSTRAK Permintaan buah Leunca (Solanum nigrum L.) terus meningkat di Indonesia sejalan dengan perkembangan restoran etnis khususnya restoran Sunda. Sebagian besar buah leunca berasal dari tanaman sampingan secara tumpangsari, sehingga produktivitas rendah. Dalam rangka meningkatkan produktivitas, percobaan pemberian nitrogen dilakukan di Kebun Percobaan Leuwikopo IPB, Bogor pada musim hujan Desember 2013 sampai April 2014. Nitrogen diberikan empat taraf yaitu 0, 60, 120, dan 180 kg N ha-1, yang disusun dalam rancangan acak kelompok dengan empat ulangan. Hasil menunjukkan bahwa bentuk kanopi, produksi bahan kering dan produksi buah serta kualitas buah dipengaruhi oleh pemberian nitrogen. Peningkatan dosis nitrogen meningkatkan bahan kering dan produksi buah. Tanaman dengan perlakuan 60 kg N ha-1 menghasilkan tinggi yang ideal bagi pemanen, dan hasil mingguan yang stabil dibandingkan dengan taraf yang lebih besar. Oleh karena itu, pemupukan nitrogen penting dilakukan untuk meningkatkan produktivitas leunca.Kata kunci: beban buah, bentuk kanopi, leunca, ranti kebo, sayuran tradisional

Gymnema sylvestre (Retz.) R. Br. ex Schult is a highly demanded antidiabetic medicinal herb native to India. There are no improved varieties available and the plant is still collected from the wild and therefore it is important to estimate the genetic variability and heritability parameters for devising appropriate crop improvement strategy. The present study was undertaken to assess the genetic variability, heritability, character association and path analysis for growth, yield and bioactive traits in 35 accessions of G. sylvestre collected from Indian South Peninsular region. Genetic variability parameters: genotypic variance, phenotypic variance, genotypic coefficient of variation (GCV), phenotypic coefficient of variation (PCV), broad-sense heritability, genetic advance and genetic advance as per cent over mean of yield and quality related characters were computed to understand the extent of variability present. High levels of GCV and PCV (>20%) were observed for most of the traits. Leaf length, leaf area, leaf yield and gymnemagenin content reported with high heritability (>60%) and genetic advance over mean (>30%) suggest that variation in these traits is influenced predominantly by the genetic factors making selection more effective in improving them. The correlation and path analysis studies highlighted the importance of selecting leaf length, leaf breadth, leaf area index, fresh leaf yield and gymnemagenin content for improving dry leaf yield of G. sylvestre. The study also identified promising morphotypes (IIHR-GS-27 and IIHR-GS-9) and chemotypes (IIHR-GS-44) which can be utilized for the commercial exploitation or can serve as pre-breeding materials in the crop improvement programmes.
