Abstract/Description: | Globally, blast incited by Magnaporthe oryzae forms major fungal diseases that can cause severe loss in yield to the extent of 70-80% in various rice ecosystems. Marker assisted backcross breeding approach was employed to incorporate blast resistance genes viz., Pi1, Pi2 and Pi54, from the donor lines BPT/lac/tetep and B95-1/A51 into blast susceptible otherwise superior cultivar Improved Samba Mahsuri. Foreground selection coupled with stringent phenotypic selection lead to the identification of 15 superior BC2F2 plants homozygous for three genes. Agro-morphological evaluation of the pyramided lines revealed that three of the selections viz., ISM10-15-101, ISM10-15-119 and ISM10-15-154 showed significant increase in no. of filled grains per panicle (30.22%) and yield (24.23%). BC2F2:3 derived lines, varied in their disease reaction to DRR isolates. Three of the Pi1+Pi2+Pi54 pyramided lines showed complete resistance to mixture of virulent races under artificial inoculation as well as in UBN test locations. |
