Assembling corn varieties containing high amylopectin and high productivity

Abstract

It is imperative that fluffy corn be developed as a substitute staple grain at this time. The goal of this research is to produce high-yielding corn cultivars with a high amylopectin content. This study had a randomized block design and using the Back Cross method. Plant three rows of the Srikandi Putih variety and one row of local waxy corn in the first year. F1 was created by crossing the Local Waxy Corn (♂) with the Srikandi Putih Variety (♀). F1 is planted in two rows, while F2 is produced by selfing. The second year, 105 F2 samples' seeds were examined for amylopectin content before being chosen. After planting the chosen F2, it selfes to create F3. 100 rows of F3 were sown, and 263 F3 plants (♀) were chosen for backcrossing with the Srikandi Putih Variety (♂), yielding BC1F1. The following seed amylopectin levels tended to rise as selection proceeded, according to the results: F1 (74.25%), F2 (74.80%%), F3 (76.60%), and BC1F1 (79.15%). The following seed production per hectare was achieved between 2018 and 2019: F1 (2.93 t), F2 (3.05 t), F3 (4.61 t), and BC1F1 (5.09 t).
