The Growth Character and Results of Hybrid Corn Parents From Three-Way Crossing to Produce Hybrid Corn Seed Variety of Bima URI 20

摘要

The character of growth and production of hybrid maize seeds in Bima URI 20 used a three-way cross. The female elders of Bima 4 variety and male elders (G180 / Mr14 x Nei 9008P). The research objective was to see the relationship between growth and three-bonded mother trees in the production of Bima 20 URI hybrid maize seeds. The research was conducted in Kendal Regency with an area of 2 hectares in MK-1 2019 through the OFCOR (On-Farm Client-Oriented Research) approach. This research uses descriptive analysis and the relationship between variables. The results showed that genetic and environmental factors influenced the growth of parent seeds. Rise of male elders 96.5%, female elders 98.6%, Tall plants 208.5 cm, male elders 148.4 cm, ear height 74.1 cm, male elders 57.9 cm, age the female flowers 50.35, and male flowers 47.8. The results of the assessment test for the parameters of ear weight assessment, seed weight per ear, and 1000 dry seed weight resulted in a value of 0.8-0.9 that indicated that the characters had a strong effect on plant productivity and growth.
