Abstract

Resistance pattern in parents produces resistance progenies predominantly. Inheritance of resistance gene against red rot intensely affected to the degree of frequency in progenies. The present study was commenced to find out the role of parental crosses to develop resistant progenies in the first clonal generation for two consecutive years. Total of 2262 progenies of 143 bi-parental and 27 local cross combinations were evaluated to red rot resistance. CoS 96260, CoS 95255, CoS 8436, Co 0238, CoSe 92423, Co 89003, Co 62198 and CoS 08272 were good parents which involved in bi-parental cross combination, produced predominantly resistant progenies ranging from 40 to 100%. The cross combination Co 8213 × CoS 96260 produced maximum proportion 100% resistant progenies, higher than CoS 95255 × CoA 7602 (83.33%) and Co 8436 × Co 1148 (80%). These parents identified as a good combiner and also found to inherit resistance gene in bulk of its progenies. These parents could be used as donor parents in red rot resistance breeding programs of sugarcane.
