Abstract:

To find out the best combination of barley varieties with different row types and plant heights, comparative trials of single species and different hybrid combinations were carried out with 10 treatments on the following widespread barley varieties in Baoshan: two-row short-stalked ‘82-1’ and ‘Baodamai 22’, and multi-row medium-stalked and long-stalked ‘Baodamai 8’, ‘Baodamai 14’, ‘Baodamai 15’ and ‘Baodamai 25’. According to the results, (1) compared with the single species, hybrid two-row short-stalked high-yielding varieties show an increase of 3.1%-14.3% in yield; (2) the best hybrid combination is the two-row variety ‘82-1’ with the hybrid multi-row variety ‘Baodamai 25’, followed by the two-row short-stalked variety ‘Baodamai 22’ with the hybrid multi-row variety ‘Baodamai 25’, and the ratio of basic seedlings is 6:4; (3) among hybrid varieties, the two-row variety ‘82-1’ is better than ‘Baodamai 22’; among multi-row varieties, the long-stalked variety ‘Baodamai 25’ is the best, followed by ‘Baodamai 8’ and ‘Baodamai 14’, and ‘Baodamai 15’ is less suitable for planting in Boshan.
