Abstract
Five mulberry varieties were used for tests. These varieties were Morus alba Linn. Var. Kaeryang- Bpong (K1), Morus alba Linn. Var. Kokuso-27 (K2), Morus alba Linn. Var. Canava-2 (K3), Morus alba Linn. Var. Suisfen (K4) and Morus alba Linn. Var. Ardnyl (K5). The agronomical parameters recorded, were shoot length, number shoots/tree, number leaves/ shoot, leaf /shoot ratio, weight of 100 leaf, number leaves/100g, leaf yield/tree, leaf yield/fadden and leaf moisture percentage. Young instars duration, fourth instar duration, fifth instar duration, total larval duration, pupation ratio, cocooning percentage, number of cocoons/liters, cocoon weight, cocoon shell weight, pupal weight and cocoon shell ratio, silk productivity, length and weight of silk filament, size of reeled thread (denier) and silk ratio (silk recovery) were registered. Biochemical analysis was done to estimate the total chlorophyll, chlorophyll A and B & ratio of chlorophyll A/B and carotenoids.
Highlights
In addition to the nature of the silkworm, specific quality requirements of worms during different phases of growth and production of eggs reflect the importance of different mulberry varieties used in feeding the silkworm
Significant differences were detected for young instars duration, fourth duration, fifth duration, total larval duration, pupation ratio, cocooning percentage and number of cocoons/liter parameters
Variety of K2 was superior for shoot length, No shoots/tree, No leaves/shoot, leaf /shoot ratio, No leaves/100 g, leaf yield/tree, and leaf yield/fadden, followed by K4, K5 and K1 variety
Summary
In addition to the nature of the silkworm, specific quality requirements of worms during different phases of growth and production of eggs reflect the importance of different mulberry varieties used in feeding the silkworm. It was reported that the nutritive effects of leaf position play a major role in the quality of silkworm growth and silk production Adeduntan (2013). The mulberry tree is an invaluable tree of immense economic importance in the silk industry for its foliage, which constitutes the chief food for the silkworm, Bombyx mori L. The improvement of productivity traits in mulberry plays a vital role in the progress of the sericulture industry (Dandin et al 2003 and Biasiolo et al 2004). In addition to cultivated lands, it is found along road shoulders and fences as well as intercropped with other crops (Metaferia, 2007)
