About advantages and shortcomings of hybrids of the first generation it is told in article. For some vegetable cultures – onions, carrots, a beet, a garden radish – it is recommended to grow up grades because of too expensive and often not paid back costs of production of hybrids.
At acquisition of seeds and planning of crops many farmers have a question: what seeds to buy, high-quality or hybrid?.
Grades are received as a result of selection and they expressed high-quality properties. F1 hybrid, or a hybrid of the first generation, receive by artificial crossing of specially picked up parental pairs. As a result in the first generation the received seeds give the plants, differing intensive growth, precocity, high productivity, a fructification druzhnost, high quality of fruits, stability to adverse conditions, diseases, wreckers. Undoubtedly possibilities of hybrids of the first generation exceed possibilities of grades. However, hybrids don’t keep the properties in the following generations, that is seeds to collect for crops it is impossible.
Production of hybrid seeds more labor-consuming, than grades therefore their seeds are more expensive much more. Hybrids of F1 of any cultures are better for growing up through sprouts not to lose any seed because of lower field vsxozhesti.
So after all, grades or hybrids? For receiving big profits it is better to grow up hybrids of vegetables. From them it is possible to receive more big and qualitative crop. Hybrids of a cucumber have the majority of pistillate flowers and are deprived of bitterness that is very difficult for achieving at traditional selection. Hybrids of late cabbage can be stored very long (till 12 months). Practically all hybrids have high marketability of fruits, are more homogeneous and leveled. Stability of hybrids to diseases, wreckers and adverse factors led to that in hothouses of a grade of vegetable cultures already practically aren’t grown up.
But for some cultures it is sometimes better to grow up grades (onions, carrots, a beet, a garden radish). Cultivation of their hybrids too expensive and not always pays off.
