Abstract
The sprouting behaviour of different 35 Mulberry varieties were taken during autumn 1999 and spring 2000 to screen out early sprouting varieties for introduction in the field for commercial exploitation. It was observed that Mandalya T-R8, TR10 and S146 are early sprouting varieties. These varieties take 13 to 14 days in spring and 7 to 10 days in autumn for sprouting. All exotic varieties were found exhibiting late sprouting characters. The sprouting in these varieties occurred only towards the second half of March and early April when temperature is comparatively higher for bivoltine rearing. The early sprouting varieties are more suitable for bivoltine rearing than the late sprouting varieties. Hence Mandalaya TR-8, TR-10 and S146 can safely be recommended for bivoltine rearing in subtropical area due to coincidence of their sprouting with bivoltine rearing schedule.
