To take advantage of hybrid vigor
, new hybrid seed corn must be bought each year and mule colts must be bought from mule breeders.
And these two populations have shown a clear hybrid vigor
effect in the fertility analysis.
The first explanation claimed that hybrid vigor
was due to hybridity per se.
Hence the present study is to undertaken to estimate the dry pod yield and its hybrid vigor
in parents and 30 hybrids and to suggest the F1 hybrids having high dry yield and yield contributing characters for evaluation of new chilli hybrids.
According to the present study, inbred lines should not be adopted as breeding strategy to obtain commercial genotypes, but they could be used for creating hybrid vigor
on crossing clones derived from selfing.
, also known as heterosis, is the miraculous phenomenon by which intercrossing two varieties of plants produces more vigorous hybrid offspring with higher yields.
The results "clearly support hybrid vigor
," says Fitzpatrick.
For more than 50 years, one of the most cherished dreams of plant breeders has been to find a way to transform corn and other cereal grains into super-plants able to reproduce by themselves without losing hybrid vigor
, desirable agronomic traits, or useful disease- or insect-resistance.
Another possible explanation for their high survival remains untested: that they experienced a hybrid vigor
(heterosis) owing to their generally heterozygous condition.
This generally leads to a more fit hybrid or the phenomenon of hybrid vigor
MPSS has jump started our efforts to understand, at the genomic level, the genetic and physiological bases of hybrid vigor
in oysters, a non model species," said Professor Dennis Hedgecock.
The better parent effects were higher in non-stress than stress suggested that if exploitation of hybrid vigor
is feasible in wheat the above hybrids would be the choice F1 hybrids to be grown in water- deficit conditions for higher yields.
