Profile:
Dr. Shyam Sundar Dey is Principal Scientist working on improvement of cole and Cucurbitaceous vegetable crops at Division of Vegetable Science, ICAR- Indian Agricultural Research Institute, New Delhi. He is working on understanding the economically important traits in cauliflower, cucumber and gourds for their improvement and development of elite breeding lines and cultivars with resilience to biotic and abiotic stresses and higher productivity. Current research interest in his programme are 1. Characterization of large set of Cauliflower, cucumber and gourd germplasm for resistance to critical biotic stresses 2. Molecular mapping of Black rot, Alternaria leaf spot and DM and understanding the associated molecular networks.

Abstract:
Hybrid breeding in cabbage: Present status and future strategies

Cabbage is an important vegetable crop and is grown on an area of 2.53 million hectares with 70.86 million tonnes of total production. It is being cultivated in almost 141 countries across the world. China and India are major growers and both countries contribute 48.3% in the global area of cabbage. Cabbage has a higher average productivity (29.35 MT/ha) than the global average of vegetable crops (19.69%). The development of hybrids mainly drove the transformative scenario in cabbage production. The hybrids are known for uniformity, adaptation, reduced crop period and higher yield. The cabbage has high extent of heterosis for Identification and use of sporophytic self-incompatibility helped earlier breeders to develop some hybrids in cabbage. But, the major progress happened after the deployment of Ogura male sterility and also the identification of a genic male sterility governed by a single dominant gene (Ms-cd1). A number of hybrids in different segments has been development worldwide. New CMS systems are also available in Brassica oleracea crops which can be easily transferred to cabbage for use in hybrid breeding. It is essential to equip the hybrid breeding programmes with diverse sterile cytoplasms to handle any risks associated with the breakdown or weakening of male sterility due to climate change or other biotic factors. Cabbage is highly heterozygous crop and attaining uniformity in parental lines requires the use of doubled haploid (DH) technology, speed breeding and molecular markers. Equipping the parental lines with better quality attributes (minerals, anthocyanin, carotenoids, glucosinolates etc.), disease or pest resistance in key to sustaining the cabbage scenario in future. The present-day focus is mainly on the fresh market and the main season cultivation, however, the emphasis is needed to tackle diverse segments such as processing, storage, fast foods etc. by ensuring the supply of affordable hybrid seeds to the farmers.
