The objective of the present work was to evaluate the physiological quality in seeds of haploidy inducers of different types and origins. To this end, between December 2015 and March 2016, a series of physiological quality assessments were conducted on nine genotypes inducing haploidy in corn, namely: the gymnogenetic inducers Stock 6, TAIL P1 and TAIL P2; the hybrid between the TAIL P1 x TAIL P2 inductors; the hybrid TAIL P2 x TAIL P1, analogous to the previous hybrid, but with inversion of the female parent at the crossing; and androgenetic inducers W23, 90109 igig, 91202 igig and 91207 igig. The tests carried out were germination, accelerated aging, emergence in a bed, emergence index, fresh and dry mass, length of aerial part and root and the ratio between these characteristics, the humidity and the weight of 100 seeds. The results indicated that the physiological quality was improved throughout the selection for greater haploid induction. The haploidy induction system (andorgenetic or gymnogenetic) does not interfere with physiological quality, however the results obtained reinforce the need for care in the multiplication and conservation of haploidy inducing seeds in tropical conditions for their use in breeding. |
