SRINAGAR: A study by researchers at Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir (SKUAST-K) has found that poor pollination could be a major reason behind the widespread occurrence of the “Hen and Chicken” disorder in Sahebi grapes grown in Kashmir.
The study, conducted by the Division of Fruit Sciences at SKUAST-K, Shalimar, has established that Sahebi is a functionally female grape cultivar, meaning it depends on pollen from compatible cultivars for effective fertilisation and fruit development.
The “Hen and Chicken” disorder is marked by grape bunches containing a mix of normal-sized berries and a large number of small, poorly developed berries. The condition reduces both marketable yield and fruit quality, with around 70–80 per cent of Sahebi grapes reportedly affected in Kashmir.
Researchers said the problem could be linked to inadequate pollination, particularly in vineyards where Sahebi is grown without suitable pollen-producing cultivars.
The study was carried out during the 2025–26 research season, when researchers examined floral morphology and pollen characteristics of nine grape cultivars under Kashmir’s temperate conditions.
The research was undertaken by Raksha under the guidance of Dr Aroosa Khalil and Dr A H Pandit, head of the Division of Fruit Breeding, Technology and Innovation.
The study found that Sahebi has reflexed stamens and non-functional pollen, confirming its functional female nature. As a result, the cultivar requires pollen from a compatible variety to achieve effective fruit set.
Based on the findings, researchers have recommended planting compatible pollinizing cultivars such as Hussaini, Thompson Seedless, Fantasy Seedless, Pusa Navrang and Manjari Naveen alongside Sahebi while establishing new vineyards.
The researchers also said timely pruning, balanced nutrient management and appropriate vineyard practices could help improve fruit development and bunch uniformity.
Grape cultivation has significant potential in Kashmir, with Ganderbal district accounting for around 206 hectares under grape cultivation and producing nearly 1,385 metric tonnes of grapes. Sahebi accounts for 54.42 per cent of the district’s grape cultivation, followed by Hussaini at 35.20 per cent.
The study is expected to help growers improve pollination management in Sahebi vineyards and reduce losses caused by uneven berry development.
