Résumé :
Persea bombycina Kost is a primary food plant of Muga silkworm, Antheraea assama Ww. Phenotypic and genotypic variability were studied in eight genotypes of Persea bombycina Kost for rooting percentage and their five contributing characters. A wide range of phenotypic variability was observed for rooting percentage, number of primary roots, number of secondary roots, length of the longest root, average length of the root and survivability. In different genotypes number of secondary roots gave highest estimate of genetic coefficient of variation followed by number of primary roots. Estimate of heritability was high in all the traits. Estimate of genetic advance was high in number of secondary roots, survival percentage and number of primary roots. Rooting was significantly correlated with number of primary and secondary roots, length of the longest root and survival percentage both at the phenotypic and genotypic level. The other characters were also significantly correlated to each other.

Résumé :
Thirty nine accessions of Som, Persea bombycina Kost. were evaluated through rearing of muga silkworm, Anthereae assamensis Helfer during two commercial seasons viz. Kotia (October-November) and Jethua (May-June) to identify the superior accessions for more silk productivity. The rearing performances on each of the som accessions were evaluated on four characters viz. effective rate of rearing (ERR), Cocoon weight, shell weight, and shell ratio percentage (SR%) by the multiple trait evaluation index (EI) method. During Kotia crop, fourteen accessions showed average EI values of >50 (ranging from 50.22 to 62.37) and during Jethua crop, twenty accessions manifested average EI values of >50 (ranging from 50.12 to 67.55). It was found that ten accessions viz. PT-11, PT-16, PT-17, PT-27, PT-28, PT-29, PT-37, PT-38, PT-34 and PT-04 exhibited average EI values of >50 in both the rearing seasons thereby indicating the superiority of these accessions to the other accessions.

Résumé :
Grey blight disease caused by Pestalotiopsis disseminata, is one of the major foliar fungal diseases that constantly affects Persea bombycina Kost, a primary host plant of muga silkworm. Under nursery condition, grey blight disease was recorded mostly in SS and S6 morphotypes of som plants. Vermicompost, PGPR and AMF, alone and in combination were applied for the improvement of the growth of eight morphotypes of som plant as well as to reduce incidence. Growth in terms of height (cm), no. of leaves and no. of branches were studied. Analysis of some major defence related enzymes such as POX, PAL, CHT and GLU was also carried out to check induction of resistance after treatment. Artificial inoculation of som plants under nursery condition with spore suspension of P. disseminata was performed and disease progression noted for 7, 14, 21 and 28 days. It was clearly seen that disease progression was slow and less in treated inoculated plants. The results emphasize the fact that application of bioinoculants can be studied in larger scale for the upliftment of the health status of muga host plants.

Résumé :
Four diploid som genotypes viz., PB003, PB004, PB005, and PB006 along with four polyploid counterparts viz., PB009, PB010, PB011, and PB012 were evaluated through rearing of Muga silkworm from brushing till spinning during spring and autumn seasons under the agro-climatic conditions of Jorhat, Assam. Observations on leaf yield per plant, parameters for rearing performances and biochemical constituents such as crude protein, crude fiber, total carbohydrate, reducing sugar, total soluble sugar and moisture content were made. The results revealed that tetraploid som genotype namely PB012 is comparatively superior than other genotypes.
