Isozyme analysis: In this study, polymorphism among parental lines of two F1 hybrids Shaktiman-1 [(CML 142 x CML 150) x CML186] and Shaktiman-2 (CML 176 x CML186) with respect to the esterase (EST), alcohol dehydrogenase (ADH), malate dehydrogenase (MDH) and acid phosphatase (ACP) was analyzed.
This study provides a diagnostic tool for rapid detection of F1 hybrid termites from field populations in south Florida.

ABSTRACT The growth characteristics and morphological features of the Atlantic bay scallop (Argopecten irradians irradians Lamarck), Chilean scallop (Argopecten purpuratus Lamarck), F1 hybrids of these species, and the offspring produced via 2 cycles of backcrossing between hybrid populations and the Atlantic bay scallop were examined to determine the feasibility of broadening the genetic basis of the bay scallop.
Seed saved from the first crosspollination of two unrelated open-pollinated plants is called F1 hybrid seed.
If you don't want to wait quite that long, buy one-year-old crowns to plant in early spring and go for an all male F1 hybrid as male plants tend to be more productive.
A lower survivorship in F1 hybrid individuals found in other hybrid zones could also be due to the incompatibility between mitochondrial and nuclear genomes, which seems to be greater between M.
4000 kg of F1 hybrid seed of these 5 combinations have been produced which will be planted during this year in different ecologies of cotton and its results will be available at the end of this year.
Only the seed companies can make more F1 hybrid seed--whose exact origins are usually trade secrets--so farmers have to buy more every year, instead of simply storing and planting their favorites for years, decades, or generations.
