“…Number of fruits per plant and single fruit weight are the entities that directly contribute to the yield per plant and to total yield per unit area. This is in evident with the experimental results of Dheemanth et al, 2020 [8] , Rangnamei et al, 2017 [9] , in tomato crop. Results obtained by Ali et al, (2012) [10] , Shresta and Sah (2014) [11] , Lekshmi and Celine (2015) [12] , for yield per plant also recorded in accordance with this experiment.…”

An experiment was conducted under polyhouse conditions with three tomato hybrids namely Arka Rakshak, Shivam and Lakshmi to find the hybrid suitable for Tiruchirappalli region of Tamilnadu. The experimental design was laid out in a Randomized Block Design with eight replications. Quantitative yield parameters such as plant height (cm), flower cluster/plant, flowers/cluster, fruits/plant, single fruit weight (g) and yield/plant (kg) were studied. Hybrid Shivam recorded the highest in Number of fruits plant -1 (63.13), Single fruits weight (96.33 g) and Yield plant -1 (5.10 kg plant -1 ).

“…Notably, UK Local-2 emerged as highly resistant in a study conducted by Kumar et al 2018 underlining the importance of genetic diversity in breeding programs aimed at developing disease-resistant tomato cultivars. Dheemanth et al, 2020 [8] identified Abhinav as the top-performing hybrid, showcasing high yield, large fruit size and notable resistance to both bacterial wilt (1.56%) and ToLCV (5.02%). The observed higher specific combining ability (SCA) in hybrid combinations like DT1504 x DT911, Pusa Rohini x DT816, and Pusa Rohini x DT806 suggests a predominance of nonadditive gene action in the inheritance of traits related to tomato leaf curl virus disease and bacterial wilt resistance.…”

Tomato (Solanum lycopersicum L.) is a crucial crop globally, revered for its nutritional value and adaptability. However, it faces significant challenges posed by the Tomato Leaf Curl Virus (ToLCV) and bacterial wilt induced by Ralstonia solanacearum. This research aimed to meticulously evaluate various tomato genotypes for their resistance to these debilitating diseases while identifying hybrid combinations with promising traits. Key findings include the identification of highly resistant hybrids such as DT1504 x DT911 against ToLCV and Ralstonia solanacearum. Assessment based on disease severity indices revealed, DT1504 and Pusa Ruby consistently exhibiting heightened vulnerability. However, genotypes like DT1504, DT911 and DT806 demonstrated commendable levels of resistance in contrast to the susceptibility observed in Pusa Ruby, Pusa Rohini, DT816 and DT806. Using line× tester analysis, the GCA and SCA hybrid combinations such as DT1504 x DT911 and Pusa Rohini x DT806 demonstrated notably negative SCA values indicating strong genetic interactions contributing to disease resistance. This study highlights the vital role of genetic diversity in breeding, emphasizing hybrids dual benefits of high yield and disease resistance. Through identifying and utilizing genetic resistance it aims to mitigate tomato diseases promoting sustainable agriculture worldwide.
