“…A marker is useful for marker-assisted breeding when the distance is less than 5 cm (Saha et al, 2014). In a study conducted by Bhutia et al (2023), the researchers identified a novel gene symbolized as 'Cl' which is associated with cluster fruitbearing in Luffa. Through linkage analysis, they discovered that the SRAP marker ME10 EM4-280 exhibited a significant linkage to the fruiting trait, which is located approximately 4.6 cm away from the Cl locus.…”

“…In eggplant, growth habit and fruit-bearing habit were reported to be governed by two and three complimentary genes (Kamani et al, 2008). So far, inheritance studies for fruit-bearing habit has been reported in chilli (Srivastava et al, 2019) and in Luffa species (Bhutia et al, 2023). The study concluded the linkage map and markers responsible for this trait along with other fruit traits.…”

In eggplant, two kinds of fruit‐bearing habits can be observed, that is, cluster and solitary. The fruits grown in cluster are small in size but contribute towards yield and productivity. In this investigation, we have studied the genetics of fruit‐bearing habit and identified the SSR markers linked to this trait. Pusa Safed Baingan 1 (cluster bearer) and Pusa Hara Baingan 1 (solitary bearer) having contrasting traits were crossed to generate F1 (20 plants), F2 (215 plants), B1 (73 plants) and B2 (64 plants). Genetic analysis of the trait was carried out using Chi‐square test. The segregation of plants in F2 suggested recessive epistasis with ratio of 9:3:4 (solitary: mixed: cluster) indicating involvement of two genes for controlling the fruit‐bearing habit. The parental polymorphic 6 SSR markers were used for genotyping F2 plants and co‐segregated with the fruit‐bearing habit (Bh1) locus in 1:2:1. A linkage map covering 63.86 cm distance was developed, the SSR marker emf11A03 was closest with a distance of 4.37 cm, emk03O04 at 12.5 cm distance, and emf21O06 at 14.5 cm. The physical positions of the SSR markers emb01J19 and emf11A03 flanking Bh1 gene were located at 4.77 mb position of contig Sme2.5_05721.1 and 5.18 Mb position of contig Sme2.5_00994.1, respectively. The findings in the present study will be helpful in marker‐assisted breeding to enhance yield in eggplant.
