    Notes: Summary The resistance sources among various test cultivars of urdbean to Colletotrichum truncatum, a leaf spotting pathogen, were identified and genetics of resistance was worked out by studying F1, F2 and F3 generations of crosses between resistant cultivars and the susceptible cv. Kulu 4 and of those among the resistant parents. The resistance was found to be controlled by single dominant genes and the resistance genes were non-allelic.

    Notes: Summary To introduce resistance to fungal and viral diseases into urdbean (Vigna mungo), it was crossed with adzukibean (Vigna angularis) to achieve an interspecific hybrid between the two species by using different non-conventional breeding methods. Partial success was obtained with the use of UV irradiated pollen, intraspecific hybrids as parents and spray of immuno-suppressants on the female parent under glass house conditions and to the extent of callusing in aseptic culture.

    Notes: Summary Studies revealed that Zn-deficiency symptoms were induced markedly by the levels of nitrogen and its source in rainfed lowland rice grown on calcareous soil. Visual Zn-deficiency symptoms recorded 3 weeks after transplanting showed that increased supply of nitrogen at puddling resulted in significant increase in the extent of deficiency symptoms of this nutrient element. Zn-deficiency symptoms got aggravated with Mussorrie Rock Phos-coated urea (MRPCU) followed by sulphur-coated urea (SCU). Zn-deficiency symptoms induced by urea supergranules (USG) and prilled urea (PU) supplying two-thirds of nitrogen as basal were found to be of moderate level. No symptoms of Zn-deficiency were noted with no-nitrogen control.
