laid out in single factor Completely Randomized Design (CRD) with replications. The
highest mycelium running rate of mother spawn (0.85 cm/day) was observed when the
rice grain was used. The minimum duration required from incubation to completion of
mycelium running of mother spawn (16.33 days) and maximum mycelium weight
(4.08) was observed in rice. The minimum duration required from incubation to
completion of mycelium running in yield packets (18.33), from stimulation to
primordial initiation (5.89 days), from primordial initiation to 1st harvest (5.67 days)
and the lowest total harvesting period (40.00 days) were found when mother spawn of
rice was used. Again, the maximum number of primordia (87.33), effective fruiting
body per packet (31.00), the highest length of pileus (5.17 cm) and width of pileus (7.49
cm) were found at mother spawn of rice. Oyster mushroom grown on sawdust
substrates where mother spawn of rice inoculated gave the highest biological yield
(175.67 g), economic yield (168.33 g) and biological efficiency (35.13%). During the
cultivation period four contaminants namely Trichoderma sp. Penicillium sp, Rhizopus
stolonifer and Aspergillus niger were isolated and identified from contaminated
substrates. Percent contamination of fungi gradually increased with the increase of days
after stimulation. After 45 days after stimulation (DAT), packets inoculated with rice
and wheat mother spawn were not contaminated. Among the treatments, the
performance of mother spawn of rice was better economically as well as growth and
yield performance for the cultivation of oyster mushroom

GENETICS AND PLANT BREEDING
SEMESTER: JAN-JUNE, 2021The present research work was conducted to study the characterization and genetic
diversity analysis of green chili during the period from October 2019 to March 2020 in rabi
season in the experimental field of Sher-e-Bangla Agricultural University, Sher-e-Bangla
Nagar, Dhaka 1207. In this experiment 20 chili genotypes were used as experimental
material in a randomized complete block design with three replications. Analysis of
variance revealed highly significant differences among genotypes for different characters
studied. The highest phenotypic co-efficient of variation (70.09) and genotypic co-efficient
of variation (69.64) was found in yield per plant (g). High heritability coupled with high
genetic advance and genetic advance in percentage of mean was found in yield per plant
(g) which indicated predominance of additive gene expression on this character and direct
phenotypic selection of this character. The genotypic correlation coefficients were higher
than the corresponding phenotypic correlation coefficients, indicating strong inherent
association between the characters under studied. Investigation on character association
indicating that yield per plant had the highest significant positive correlation with
individual fruit weight in both genotypic and phenotypic level. Path analysis revealed that
plant height (cm), number of primary branches and individual fruit weight (g) showed
positive direct effect on yield per plant (g) indicating that direct selection based on these
traits. Principal component analysis identified three principal components, which
contributed 68.06% of cumulative variance. The 20 genotypes were grouped into five
different clusters. The highest intra-cluster distance was computed for cluster V. The
maximum inter cluster divergence was observed between cluster III and V and the lowest
was between cluster I and II. Therefore, considering the magnitude of genetic distance,
contribution of character towards divergence, magnitude of cluster mean and agronomic
performance the genotypes G18 from cluster V for number of primary branches, G14 from
cluster IV for individual fruit weight (g) and days to first harvest and G5, G11 and G13
from cluster III for yield per plant might be considered better parents for future

PLANT PATHOLOGYA laboratory experiment was carried out to evaluate the seed health and
quality status of selected seed spices and culinary herbs viz. coriander,
cumin, dill, black cumin, fennel and fenugreek during July 2019 to
December 2020 at Seed Health Laboratory of Department of Plant
Pathology, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh.
Seeds of 15 varieties were collected from local market and Spice
Research Centre, BARI, Bogura. Seed health study was conducted by
following the rules of International Seed Testing Association (1999). In
inspection of dry seed method, pathogenic structures, fruiting body and
physical abnormalities viz. deformed, shrinkage, swelling, spotted and
undersized seeds were recorded. It was exposed that seeds of selected
spices and culinary herbs yielded six fungal species in blotter method.
Through blotter plate method, the incidence and frequency of identified
pathogen has been recorded. The identified fungi were Aspergillus flavus,
Aspergillus niger, Fusarium sp., Alternaria spp., Chaetomium sp. and
Rhizopus sp. Percent pathogen incidence of identified fungi and
unidentified pathogen were also recorded. The highest percentage of seed
borne pathogen infection was found in the local seeds; 68.2% in
coriander, 43.65% in cumin, 71.9% in dill, 47.5% in black cumin, 56% in
fennel and 54.5% in fenugreek seeds. Most of the seed-borne pathogens
reduced the germination and produced diseased seedlings in blotter
method. Considering the frequency and occurrence of seed borne
pathogen, 54% pathogenic infection was recorded in three varieties of
coriander. However, in cumin 81.88% seed borne pathogenic infection
was found in two varieties. Moreover, in dill, black cumin, fennel and
fenugreek seeds, seed borne pathogenic infection were 49.5%, 71,88%,
63.75%, 61.5% respectively
