  1. Data presented as the means with standard deviations were obtained from plants in a randomized complete block design with three replications under natural conditions at Jiamusi in 2016 and 2017. The planting density was 30 cm × 20 cm and one plant per hill
  2. GL Grain length, GW Grain width, HGW Hundred grain weight, TYP Total grain yield per plant, PNP panicle number per plant, GNP grain number of main panicle, PH plant height, PL main panicle length, DTH Days to heading
  3. *represents significance at p ≤ 0.05 based on Student’s t-tests, n = 10
  4. aThe planting density was 30 cm × 20 cm and one plant per hill
  5. bThe planting density is 30 cm × 20 cm and three to four plants per hill
  6. cThe planting density is 30 cm × 14 cm and three to four plants per hill; − indicates no data
