Hybrids and genitors showed a low amount of meiotic abnormalities and high pollen viability can be expected.
Meiotic abnormalities recorded in hybrids and their genitors.
Chromosome association between the genitor genomes is required to recombine the desirable genes to create genetic variability to be exploited in the breeding program.
We see this need particularly in the contrast of genitor and pater.
Important though these are for the well-being of society, the absence of a genitor from the home is not the central loss.
In terms of the amplitude of variation in the effects of genitors and between genitors, it can be concluded that the genitors differ when the amplitude of variation is greater than twice the standard deviation; that is, there is genetic variability between the inbred lines (SINGH; CHAUDHARY, 1985).
2006), who indicated that when there is a low level of heterosis predictions about the hybrid should be made based on a mean of the genitors.
In the case of GY, for which there were environmental effects both for the inbred lines and for heterosis and its components, an indication of genitors for producing hybrids based on the performance of inbred lines heterosis is a fragile strategy, especially when the participation of this effect in total heterosis is markedly inferior.
The inbred lines did not have good values "per se" for popping expansion, demonstrating that the best genitors for production are not the best for grain yield.
The treatments were the 45 F1 hybrids and the 10 genitor lines.
