Study on the effect of different rootstocks on cane biochemical composition in grape varieties
The present investigation aimed to study the effect of different rootstocks, viz. Dogridge (V. champini), 110R (V. berlandieri × V. rupestris), 140RU (V. berlandieri × V. rupestris), and 1103P (V. berlandieri × V. rupestris) on cane biochemical composition, yield and berry quality of new grape vari...

| Summary: | The present investigation aimed to study the effect of different rootstocks, viz. Dogridge (V. champini), 110R (V. berlandieri × V. rupestris), 140RU (V. berlandieri × V. rupestris), and 1103P (V. berlandieri × V. rupestris) on cane biochemical composition, yield and berry quality of new grape varieties. viz. Manjari Medika, Manjari Naveen, Manjari Kishmish along with Thompson Seedless. Experiment was conducted at ICAR-National Research Centre for Grapes, Pune, Maharashtra, during the year 2022–23 and 2023–24. Results showed that cane biochemical content varied significantly among the different rootstock-variety combinations influencing the grapevine fruitfulness, yield and berry quality. Among the rootstock variety combinations, grape variety Manjari Medika grafted on 140RU rootstock exhibited highest levels of carbohydrate (108.05 mg/g), proline (5.07 µmoles/g), and protein (5.90 mg/g) content. However, Manjari Naveen grafted on 110R showed the highest tannin (5.71 mg/g) and phenol (4.43 mg/g) content. Similarly, Manjari Medika × 140RU rootstock exhibit highest fruitfulness (95.74%), yield/vine (18.47 kg) with optimum berry quality, while lowest fruitfulness was recorded in Thompson Seedless × 1103P (81.13%) and minimum yield/vine in Manjari Naveen × Dogridge (8.46 kg), respectively. The study identified a notable linear correlation between yield per vine and cane biochemical, viz. carbohydrates, phenol, tannin, proline and protein. Further, Manjari Medika × 140RU is suggested as promising rootstock-variety combinations for quality grape production at tropical climate of India.
