Evaluation of Inherited Resistance Genes of Bacterial Leaf Blight, Blast and Drought Tolerance in Improved Rice Lines

Improved rice lines were developed frome three parents with the resistance or tolerance to bacterial leaf blight, blast and drought stress, respectively, using single-, double- three-way crosses. The improved assessed for agro-morphological yield traits under non-drought stress (NS) reproductive-stage (RS) treatments. mean comparison of measured between parent plants progenies (improved lines) similar, there significant non-significant differences among (genotypes) NS RS. Smilarly, was in interaction both varieties Cluster 3D-model principal component analysis did not generate categorical clusters according crossing methods, no exclusive method inclined variations high-yielding, disease resistant, drought-tolerant compared their parents. All methods good this crop improvement program without preference any, despite number genes introgressed.
