Comparative studies on crossability in some popular cultivars of mulberry (Morus Spp.).

The breeding system consists of mulberry (Morus spp.) cultivars such as Mysore local and Sujanpur 1 (Females) and S34, S13, DD, RFS 135, Ber.S1, Ber.C776 and V1 (males) were examined. In the month of March, the maximum seed set percentage ranges from 65.54 to 74.81 was observed in cross combinations using V1, S13, RFS135 as male parents. Whereas in September, the maximum seed set ranges from 62.82 to 68.40 was observed in cross combinations using Ber.S1, S13 and DD as male parents. The environment or a particular period such as temperature, humidity influenced on the rate of seed set. Pollen fertility is maximum in S34, S13, and V1 (97.0, 95.50 and 95.0). March month is better for crossability than in the month of September. [ABSTRACT FROM AUTHOR]
