Study Notes

Senior Scientist at ICAR-Indian Institute of Vegetable Research

BK Singh is a Senior Scientist in the Division of Crop Improvement at ICAR-Indian Institute of Vegetable Research (IIVR) in Varanasi.

Research Areas

Singh's research focuses on developing high-yielding vegetable varieties, particularly in cole crops, root vegetables, and leafy greens.
His research aims to:
- Develop high-yielding varieties and parental lines with good combining ability and create heterotic hybrids.
- Identify stress-tolerant genotypes, resisting heat, humidity, and diseases like black rot.
- Tropicalize temperate vegetables, adapting them to warmer climates.
- Generate robust cytoplasmic male sterility (CMS) lines, crucial for hybrid breeding and economical F1 seed production.
- Enhance nutrient, vitamin, pigment, and antioxidant content in various vegetable varieties.

Key Accomplishments

Cauliflower: Developed varieties and CMS lines producing curds at temperatures of 20-30°C.
Radish: Created varieties and hybrids of white and red radishes suitable for cultivation across different seasons, including spring, summer, autumn, and winter.
Carrot: Developed varieties and promising lines of red, orange, black, yellow, cream, and rainbow carrots.
Leafy Chenopod (Bathua): Created varieties of leafy chenopod, a green leafy vegetable, with green and purplish-green varieties.
Poi (Basella): Developed distinct varieties of Poi, a leafy vegetable, with different growth habits, leaf shapes, and petiole colors.
Beet Leaf (Palak): Developed promising lines of beet leaf suitable for year-round cultivation.
French Bean (Snap Bean): Created varieties with purple and green pods, along with early-maturing types for autumn sowing.
Tropicalization of Temperate Vegetables: Achieved successful tropicalization of kale, cabbage, and orange carrot.

Important Genetic Stocks and Technologies

VRRAD- 201 (Radish): The first Ogura-CMS line developed in the public sector in India. It features a robust CMS system, excellent combining ability, and a unique sinuate leaf morphology.
VRRAD- 12 (Radish): The second Ogura-CMS line developed in the public sector in India. It also features a robust CMS system, combining ability, and a lyrate leaf morphology. It excels at producing non-tapering, white roots during the winter season.
Kashi Kale- 1 (Kale): The first tropical kale developed globally. Unique in its ability to bolt and produce seeds in the spring season without needing vernalization.
Kashi Baramasi (Beet Leaf): Offers attractive, smooth, and succulent leaves. This variety excels in heat and humidity tolerance and exhibits delayed bolting, making it suitable for year-round cultivation.

Key Vegetable Varieties and Hybrids

Kashi Gobhi- 25 (Cauliflower): This variety forms curds at a moderately warm temperature (22- 27°C) and excels in transplanting during late July to early August. It produces hemispherical, white, and compact curds.
Kashi Arun (Carrot): Features attractive red roots, a self-colored core, a triangular shape, and a high total soluble solids (TSS) content.
Kashi Krishna (Black Carrot): This variety boasts black (solid purple) roots with a high yield potential and is exceptionally rich in anthocyanins and antioxidants.
Kashi Lohit (Red Radish): Offers attractive, red-colored roots with a high anthocyanin content and good vitamin C and antioxidant activity.
Kashi Mooli- 40 (Radish): Produces a high root yield and tolerates pithiness and delayed bolting.
Kashi Aardra (Radish): Showcases attractive, dark green leaves and long, icicle-shaped roots.
Kashi Bathua- 2 (Leafy Chenopod): Contains abundant vitamin C, vitamin A, folic acid, minerals, and antioxidants.
Kashi Bathua- 4 (Leafy Chenopod): Features purplish-green leaves and offers a notable content of vitamin C, vitamin A, folic acid, minerals, and antioxidants.
Kashi Rajhans (French Bean): This variety is bushy, with thin, round, slightly curved pods and white seeds.
Kashi Baingani (French Bean): Grows pole-like, with purple pods rich in anthocyanins and antioxidants, and light-brown colored seeds.
Kashi Agrim (French Bean): A bushy, early-maturing French bean variety with short duration, resistant to sclerotinia rot disease. Its pods are tender, green, and free from parchment.
Kashi Baramasi (Beet Leaf): Offers attractive, smooth, and succulent leaves. This variety excels in heat and humidity tolerance and exhibits delayed bolting, making it suitable for year-round cultivation.

Contribution to National Gene Bank

Singh's research has contributed 166 genetic resources, including varieties, CMS lines, advanced lines, germplasm, to the National Gene Bank (NBPGR) in New Delhi. This diverse collection encompasses various vegetables and spices, including cauliflower, kale, radish, carrot, spinach, leafy chenopod, French bean, and more.
