In general, Indian soils are not deficient in boron (B), but in some pockets in the northeastern parts of the country this problem occurs. B deficiency symptoms vary with the kind and age of the plant, the conditions of growth, and the severity of deficiency. Each crop produces its characteristic growth abnormalities associated with B deficiency. In wheat, it causes floret infertility or grain set failure. The Directorate of Wheat Research has conducted some probe experiments in the form of preliminary screening nurseries at a few selected locations during 1988-89 and 1989-90. It was concluded that varieties BW 11, BW 1008, and HDR 77 appear to possess a fair degree of tolerance to B deficiency, while HD 2285, HD 2402, and Sonalika may be classified as moderately tolerant
