Abstract:
Under Kashmir climatic conditions propagation of mulberry is done in the month of March which involves the usage of mulberry twigs and results in minimizing the availability of the mulberry leaf for silkworm rearing in the ensuing rearing season. With the aim of propagating mulberry without compromising reduction in rearing quantum this study was taken up. The experiment was conducted both under controlled (polyhouse) and natural conditions (open) at the experimental farm of the college during 2017-18. Experimental material comprised of 8 mulberry genotypes viz Mandaliya, Chinese white, SKM-27, Rokokuyaso, Kokuso -21, KNG, Ichinose and Goshoerami. Sand, clay and farmyard manure in the ratio of 6:3:1 was used as rooting media in polythene bags having the size of 4" × 11".

The experiment was conducted both under controlled (polyhouse) and natural conditions (open) at the experimental farm of the college during 2017-18. Experimental material comprised of 8 mulberry genotypes viz Mandaliya, Chinese white, SKM-27, Rokokuyaso, Kokuso -21, KNG, Ichinose and Goshoerami. Sand, clay and farmyard manure in the ratio of 6:3:1 was used as rooting media in polythene bags having the size of 4" × 11".
The cuttings of 12-15 cm length with diameter of 1.2-1.5 cm were prepared from the pruned shoots from which leaf had been harvested for spring rearing. One set of cuttings in polythene bags were kept under controlled condition (polyhouse) and the other set of such cuttings in similar polythene bags were kept under natural condition (open). Sprouting percentage of different varieties under study indicated that sprouting percentage in T1 (Mandaliya), T2 (Chinese white), T3 (SKM-27) and T4 (Rokokuyaso) reached maximum on 38th DAP under controlled condition (polyhouse) and on 52nd DAP under natural condition (open). Sprouting percentage in T5 (Kokuso-21), T6 (KNG), T7 (Ichinose) and T8 (Goshoerami) reached maximum on 24th DAP under controlled condition (polyhouse) and 31st DAP under natural condition (open). Under controlled condition (polyhouse) highest percentage of rooting (98.61%) was recorded in T1 (Mandaliya) and least rooting percentage of 19.44 percent was recorded in T6 (KNG), while as under natural condition (open) highest percentage of rooting (98.27%) was recorded in T1 (Mandaliya) and T4 (Rokokuyaso) and least rooting percentage of 15.00 percent was recorded in T6 (KNG). Under controlled condition (Poly house) highest root biomass (g), root volume (cm³), length of longest root (cm), number of roots/sapling, total root length(cm), sapling height (cm), sapling thickness (cm), number of leaves/sapling, shoot biomass(g) and root: shoot ratio was recorded in T3 (SKM-27), T3 (SKM-27), T1 (Mandaliya), T3 (SKM-27), T1 (Mandaliya), T2 (Chinese white), T2 (Chinese white), T3 (SKM-27), T3 (SKM-27) and T5 (Kokuso-21) with the values of 2.04, 2.11, 21.47, 18.78, 175.00, 25.77, 1.70, 12.33, 8.29 and 0.40 respectively. Under natural condition (open) highest root biomass(g), root volume (cm³), length of longest root (cm), number of roots/sapling, total root length(cm), sapling height (cm), sapling thickness (cm), number of leaves/sapling, shoot biomass(g) and root: shoot ratio was recorded in T3 (SKM-27), T3 (SKM-27), T1 (Mandaliya), T3 (SKM-27), T3 (SKM-27), T1 (Mandaliya), T3 (SKM-27), T1 (Mandaliya) T3 (SKM-27) and T8 (Goshoerami) with the values of 2.71, 2.78,29.18,20.00, 218.84, 34.22, 1.69, 16.06, 10.32 and 0.34 respectively.
