Abstract

The variability in different reproductive characters in 326 mulberry germplasm accessions (Exotic-114 and Indienous-212) from diverse geographical and genetic origin was studied. Sex expression revealed that 223 (68.40%) are dioecious and 103 (31.60%) monoecious. Among dioecious 192 (58.90%) bear pistillate (female) and 31 (9.51%) staminate (male) inflorescence. Analysis of variance showed highly significant difference between accessions in both male and female reproductive characters studied. In the male reproductive characters highest variability was observed in peduncle length and least in pollen size and viability. The female reproductive characters like number of flowers/catkin style length and sorosis weight exhibited high co-efficient of variation. Majority of the bisexual catkins exhibited different degree of dichogamy with self incompatibility. The variability recorded among different reproductive parameters could be used for selection of suitable parents as well as utilization in effective breeding programme for mulberry crop improvement.
