Abstract
The present investigation entitled “Studies on macropropagation in Red
banana (Musa AAA)” was carried out during 2017-18 at the Department of Fruit
Science, Kittur Rani Channamma College of Horticulture, Arabhavi, University of
Horticultural Sciences, Bagalkot, Karnataka.
Kamalapur Red banana is a geographical indicator crop and getting more
popular in Karnataka. As demand for red banana planting materials is increasing,
there is an urgent need for the production of low cost disease free healthy planting
materials. In correspond to this problem studies were conducted to know the effect of
different substrate, growth hormones and bio agents on plantlet regeneration in red
banana through macro propagation. Among different substrates, potting media [soil +
FYM (2:1)] (T1) showed significantly best result in terms of number of days taken for
first bud emergence (24.40), number of primary buds per corm (3.40), number of
plantlets after secondary decapitation (6.26) and total number of plantlets per corm
(9.80).
Among different growth chemicals and bio-agents treatments, potting media
BAP took less number of days for first bud emergence (27 days) whereas, treatment
combination of VAM + BAP + P. fluorescens + T. harzianum (T10) recorded
maximum of primary buds per corm (3.93), number of plantlets after secondary
decapitation (12.26), total number of plantlets per corm (15.58) and took less number
of days for secondary decapitation (49.43). Root colonisation (98%) and number of
chlamydospores/50 g of soil (1008) of VAM also recorded more in T10. Population of
T. harzianum, P. fluorescens and A. brasiliense were recorded maximum (9×106
cfu/g, 6×106 cfu/g and 4×106 cfu/g respectively) in the treatments where these
microbes are inoculated alone respectively.
