Prikaz novih ranostasnih NS sorti soje

Abstract

Rezultat intenzivnog, kontinuiranog rada na oplemenjivanju soje u Institutu za ratarstvo i povrtarstvo, u Novom Sadu, je sve veći broj priznatih sorti ove industrijske biljke. U poslednjih nekoliko godina napravljen je značajan iskorak u oplemenjivanju genotipova kraćeg vegetacionog perioda (grupa zrenja 0), a posebnu pažnju zaslužuju Valjevka, Bečejka, Galina i Alisa. Rezultati višegodisnjih testiranja u ogledima, kao i prinosi ostvareni u proizvodnji, ukazuju da će novopriznate sorte znatno poboljšati postojeći sortiment soje u našoj zemlji, ali i u susednim državama, u kojima su takođe registrovane. U radu je opisan postupak stvaranja, navedene osnovne morfološke karakteristike, prinos i kvalitet zrna novih ranostasnih sorti, pri različitim uslovima gajenja.

The newly-approved cultivars Valjevka, Galina, Bečejka and Alisa are the most recent achievement in soybean breeding at Institute of Field and Vegetable Crops, Novi Sad. Results of numerous small- and large-plot trials conducted under a variety of agroecological conditions in the country and abroad indicate that an evident progress has been made in respect to the currently available early cultivars. Improvements have been made in yield level and stability as well as in the technological quality of grain, especially in the case of Bečejka and Alisa. Alisa has been noted to express a satisfactory tolerance to unfavorable, dry conditions, so it is recommended for growing in arid regions. In years with abundant rainfall and in irrigation, the cultivar is prone to lodging which reduces its yield performance. Valjevka and Galina have a high yield potential which comes to full expression under favorable growth conditions and in irrigation. Bečejka has a stable performance under a variety of growth conditions. All four cultivars have performed well in commercial production and their acreages have increased steadily. These cultivars will undoubtedly improve the assortment of soybean cultivars currently available in our country.
