Phenotypical correlations between agronomical characters in Prata type bananas (Musa) and its implications on yield estimate

摘要

This research aims to estimate?correlations between?agronomic?traits?and yield in?Pome bananas, contributing to the elaboration of?models for estimation of?harvest.?Agronomic traits?were evaluated in?98?plants of ‘Dwarf Prata’?and 96?‘BRS?Platina’,?considered?replicates and sampled?at random.? Correlations between?the masses of the?bunch, and hands?and plant height;?pseudostem perimeter?at ground level,?at 30?cm?and?at 100?cm?in height; number of?green leaves; mass of the bunch; number?of hands?and fruits per?bunch;?mass of the hands;?mass, length?and diameter?of the stem, and?mass of the fruit of the?external row?from the?first?to?the tenth?hand were estimated.?The?highest correlation coefficient?between yield and?vegetative traits?for?‘Dwarf Prata’?and ‘BRS?Platina’, was obtained for pseudostem perimeter?at ground level,?indicating?its greater potential?to compose harvest estimation models.?The correlations between?the masses of the?bunch and hands?with yield?traits,?for?both genotypes,?showed a higher potential?for?predicting?the number of?hands?and?fruits.?Appropriate correlation estimates are associated with the?fourth and?fifth?bunch,?for the ‘Dwarf Prata’?and ‘BRS?Platina’,?respectively, using?the mass of the?fruit of the?external row.
