dc.description.abstractThe present study was conducted on segregating populations of two crosses viz. HG 563 (Resistant) X PNB (Susceptible) and HG 75 (Resistant) X PNB (Susceptible) grown during kharif 2010 to screen advanced F3 and F4 progenies for bacterial leaf blight resistance under artificial inoculated conditions, F2 populations for number of gene governing resistance and to perform diversity analysis in advance lines for resistance and yield components. Observations were recorded on plant height, number of branches per plant, number of pods per plant, seeds per pod, 100 seed weight, seed yield per plant, bacterial leaf blight disease incidence, days to 50 per cent flowering, days to maturity, crude protein content, gum content and total phenol. In F2 populations of both crosses, a ratio of 13 : 3 was observed which indicated the presence of epistatic (Inhibitory) interaction. Hierarchical cluster analysis indicated that Clusters I and III gave the best performance for yield and its components in cross HG 563 X PNB and clusters I, III and V were found better in cross HG 75 X PNB. In principal component analysis, first principal component explain 78.93 per cent and 78.47 per cent variability in crosses HG 563 X PNB and HG 75 X PNB, respectively. In cross HG 563 X PNB, variables exhibited high loading of different factors in such a manner that principal factor I and principal factor III could be designated as yield factor and disease factor, respectively. In another cross HG 75 X PNB, principal factor I and principal factor II could be designated as maturity factor and yield factor, respectively. Total phenolic content was increased as disease reaction increase in plants.en_US
