Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

In this article presents the comparative data on assessing the effectiveness of artificial forced hybridization of proso millet (Panicum miliaceum L.) in the field conditions. In the research work, several castration methods were used: castration with tweezers or manual, water-thermal and chemical. According to the data , high hybridization performance was obtained using chemical castration, i.e. spraying panicles with a 2.5% aqueous solution of 2,4-dichlorophenoxyacetic acid. Using this method allowed to obtain 3355 pieces of hybrid seeds from 15 combinations, while the percentage of seed set on average was 43.6%. This indicator is higher than manual castration and water-thermal castration by 83.2% and 50.9%, respectively; in addition, this method is the least labor-intensive.
