The relative impact of different food plants (diets) namely foliages of castor, kesseru , payam
and Topioca plants on the four different mutant strain viz; yellow plain, yellow zebra ,G.B
Plain ,G.B Zebra in respect of qualities of their eri cocoon and eri silk yarn have been
evaluated under the reeling parameters. Result indicate that among the four different food
plants like foliages of castor followed by kesseru have been found evidently better than the
foliages of payam and Topiocal in respect of average cocoon weight (gm)4.10, 3.55, 3.98, 3.10,
Average shell weight (gm) 0.55, 0.45, 0.52, 0.41, Average shell ratio 13.91, 12.0, 13.0, 11.55,
Average lengt- h of silk yarn (mtrs) 2510, 2350, 2498, 2285, Average size of eri silk (D)13D,
11D, 12D, 19D, Average production of eri silk per hr(gm)13.70, 12.50, 13.10, 11.95, Average
tenacity of fibre (g/d) 14.0, 11.0, 12.0, 10.0. As far as qualitative differences of all the four
food plants in relation to qualities of eri cocoon and eri silk yarn are concerned the castor
along with kesseru food plants have achieved the status of supremacy primary food plant and
payam and tapioca the states of secondary food plants .These variation show that the qualities
and production of eri silk cocoon and eri silk yarn depends on the different food plants.
