Annual Report 2009-2010 - Central Sericultural Research ...

Kg/plant. A study on stability of F 1 selections has yielded superior performance of S-
106, S-145 and S-140 in that order as regards their leaf yield. The results are in
conformity with their behaviour analyzed by way of joint scoring.
Furthermore, plantation of 11 shortlisted selections was raised for demonstration
purposes at CSR&TI, Pampore and for studying their behaviour after transplantation.
Subsequently survival of the saplings after transplantation and sprouting percent
of the selections has been recorded. Moreover, some visual observations have
been recorded in order to substantiate the F 1 selections as regards other traits. The
ranking of S-140 which stood first is in conformity with its ranking by joint scoring
method as regards survival (%) after transplanting.

Fifty eight accessions representing five species namely M. multicaulis, M. alba, M.
indica, M. bombycis and M. Kayayama were evaluated at Central Sericultural Research
and Training Institute, Pampore. Out of 58 accessions, 33 were of temperate
and 25 of tropical origin. Information of 27 morphological traits namely, growth nature,
branching nature, young shoot colour, mature shoot colour, phyllotaxy, lenticel
density/sq.cm, lenticel shape, bud shape, leaf apex, leaf shape, leaf margin, leaf
base, leaf surface, leaf texture, leaf nature, leaf lobation, leaf colour, leaf glossiness,
leaf area (sq. cm), internodal distance (cm), weight of 100 fresh leaves (g), leaf
yield (kg/plant/crop), moisture content (%), moisture retention (%) after 8 hours
and sex expression was generated to develop a catalogue involving the characterization
of mulberry genotypes under temperate conditions. Out of the 58 genotypes,
18, 1, 1, 2, 1, 1 and 34 are from Japan, China, Russia, Italy, France, Burma and
India, respectively. The total numbers of accessions were grouped into two majour
groups i.e. temperate and tropical with the object to promote utilization, classification
of mulberry based on their origin since it can assist in making breeding programmes
meaningful and directional. Moreover, some economically important characters
namely, number of shoots, total shoot length, internodal distance, weight of
100 leaves, leaf area, leaf petiole ratio and leaf yield/crop were recorded. Data so
generated was pooled for drawing the conclusions.
Information on sexuality of 58 genotypes revealed 72.70, 24.20 and 3.00% are dioecious,
monoecious and bisexual respectively among the temperate genotypes,
