Morphological, biochemical and sensory analysis of selected <italic>Actinidia callosa</italic> var<italic>. strigillosa</italic> female accessions from the existing wild populations in North Sikkim, India.

An analysis of wild kiwifruit (<italic>Actinidia callosa</italic> var. <italic>strigillosa</italic>) fruit samples from North Sikkim district of Sikkim state of Northeast India resulted in the identification of six promising female accessions, viz. SKNLA-11, SKNBC-01, SKNBC-02, SKNLC-02, SKNLC-07, and SKNZM-02. These selections exhibited significant variation in performance across desirable horticultural traits. Morphological parameters, including fruit weight (3.69–6.33 g), length (18.76- 26.71 mm), diameter (16.26- 19.76 mm), size (length × diameter) (342.56- 495.20 mm2), length-to-diameter ratio (1.03–1.57), stalk length (13.31–18.56 mm), and fruit yield (2.50- 8.50 Kg/vine), were assessed. Biochemical characteristics such as total soluble solids (17.20 −17.76 °B), titratable acidity (0.84–1.19%), total sugars (9.52–10.60%), reducing sugars (7.14–8.30%), non-reducing sugars (1.87–2.68%), sugar-acid ratio (8.26–11.33), ascorbic acid (31.20–41.60 mg/100g), and total phenols (33.31–94.88 mg GAE/100g) were examined. Sensory evaluation was carried out by a panel of judges, rating flavour (6.00–8.00), texture (5.40–8.20), aroma (5.80–8.50), taste (6.00–8.00) and overall acceptability (5.90–7.88) on a scale of 1 to 9. Notably, SKNBC-01, SKNLC-02, and SKNBC-02 excelled in overall acceptability. These selected accessions displayed significant variation in bloom date, anticipated harvest date, and harvesting period (in days). [ABSTRACT FROM AUTHOR]
