    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 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.
