“…The maximum number of fruit per plant was produced by 13/BRBW/RES-3 (21.11) and the minimum was recorded in 2012/BRBW . Wide variations in quantitative characters of brinjal genotypes tested previously in the Gangetic plains of West Bengal were also recorded by Das et al, (2010), Chattopadhyay et al, (2011), Shende et al, (2016 and Dutta et al, (2018). It was found that bacterial wilt resistance in brinjal is tightly linked with small fruit size.…”

Brinjal production is threatened by bacterial wilt caused by Ralstonia solanacearum in the developing world. Evaluation in search of best performing genotypes against bacterial wilt disease and incorporating their genes in commercial cultivars is an effective attempt to the problem. Studies on genetic variability and heritability, along with degree of association between the various characters and direct effects of yield contributing characters on total yield, is of paramount significance in framing an appropriate breeding strategy. The proper choice of parent based on genetic divergence is a pre-requisite in plant breeding programme. In the present study reactions of 23 brinjal genotypes, in terms of bacterial wilt incidence differed at different days after transplanting (DAT). Thirteen genotypes showed resistant reactions, five genotypes were categorized as moderately resistant, and two genotypes each exhibited moderately susceptible and susceptible reaction up to 90 DAT. Resistant genotypes had comparatively lower mean fruit weight than other categorized groups, revealing the fact that small fruited genotypes are linked with disease resistance. High heritability coupled with high genetic advance was recorded in bacterial wilt incidence and other important traits indicating that the selection among the genotypes can bring about significant improvement in disease tolerance due to presence of additive genes in trait. The absence of relationship between genetic diversity and geographical distance indicated that selection of genotypes for hybridization should be based on genetic divergence rather than geographic diversity. Based on multivariate analysis and average values three elite brinjal genotypes 16/BRBW RES-2, 2012/BRBW RES-5 and 2012/BRBW RES-6, which had recorded high bacterial wilt resistance coupled with diverse horticultural traits, could be utilized as donor parents either for developing hybrids or to isolate promising lines, in segregating generation, resistant to this disease.

“…An important limiting factor in establishing a founder population is the likelihood of a male and a female emerging in temporal and spatial proximity to locate each other and mate. Recall that border interceptions of insects are a poor predictor of successful establishment (Kenis et al., 2007 ; Caley et al., 2015 ).…”

Following a request from the European Commission, the EFSA Panel on Plant Health performed a quantitative risk assessment of Leucinodes orbonalis (Lepidoptera: Crambidae), the eggplant fruit and shoot borer, for the EU. The assessment focused on potential pathways for entry, climatic conditions favouring establishment, spread and impact. Options for risk reduction are discussed but effectiveness was not quantified. L. orbonalis is a key pest of eggplant (aubergine/brinjal) in the Indian subcontinent and occurs throughout most of southern Asia with records mostly from India and Bangladesh. The main pathway of entry is fruit of solanaceous plants, primarily exotic varieties of eggplant, Solanum melongena and turkey berry, S. torvum. The trade in both commodities from Asia is small but nevertheless dwarfs the trade in other Solanum fruits from Asia (S. aethiopicum, S. anguivi, S. virginianum, S. aculeatissimum, S. undatum). Other Solanum fruits were therefore not further assessed as potential pathways. The trade in eggplant from Asia consists of special fruit types and caters mostly to niche markets in the EU, while most eggplant consumed in Europe is produced in southern European and northern African countries, where L. orbonalis does not occur. Using expert knowledge elicitation (EKE) and pathway modelling, the Panel estimated that approximately 3-670 infested fruit (90% certainty range, CR) of S. melongena or fruit bunches of S. torvum enter into regions of the EU that are suitable for L. orbonalis establishment each year. Based on CLIMEX modelling, and using two possible thresholds of ecoclimatic index (EI) to indicate uncertainty in establishment potential, climates favouring establishment occur mostly in southern Europe, where, based on human population, approximately 14% of the imported produce is distributed across NUTS2 regions where EI ≥ 30; or 23% of the produce is distributed where EI ≥ 15. Escape of adult moths occurs mostly from consumer waste. By analysing results of different scenarios for the proportion of S. melongena and S. torvum in the trade, and considering uncertainties in the climatic suitability of southern Europe, adult moth emergence in areas suitable for establishment is expected to vary between 84 individuals per year and one individual per 40 years (based on 90% CR in different scenarios). In the baseline scenario, 25% of the solanaceous fruit from Asia

A study on heterosis in brinjal was carried out during the year 2019-20 at the Department of Genetics and Plant Breeding, Annamalai University. Seven genotypes were hybridised in full diallel fashion and the resultant 42 hybrids were evaluated along with parents in RBD. The mean squares of the 11 traits revealed significant differences among the entries. The hybrid ICO-345590 x Arka Kusumkar recorded high heterobeltiosis for fruit yield per plant and its associated traits except for fruit grith, fruit length, plant height, and days to first harvest. High standard heterosis was recorded by the hybrid ICO-344674 x ICO-383119 for plant height, ICO-344674 x Arka Kusumkar for days to first harvest, Arka Kusumkar x ICO-345590 for fruit length and ICO-345590 x ICO-545862 for fruit girth. The application of heterosis in brinjal will aid in the production of superior cross combinations, which will help meet the expanding demand for brinjal due to its bioactive properties.
