Karakter Morfologi Keturunan F4 Hasil Persilangan Bebas Tiga Tetua Jagung (Zea Mays L.)

Abstract

Corn is a food crop commodity that is often consumed by the Indonesian people. Development of plant varieties needs to be done to produce superior varieties. Combination of several traits is done to obtain certain content and traits in a plant. The purpose of this study was to determine the morphological characteristics of F4 generation corn plants which are expected to be useful as a genetic source for the formation of a new basic population as a selection material to form the expected variety. The research method used was a descriptive method by observing 110 plant samples. The characters observed in this study were taken based on IPGRI guidelines. Data analysis was used to determine heritability and Genetic Diversity Coefficient (GDC) and Phenotype Diversity Coefficient (PDC). The results showed that the highest GDC value was found in the parameter of the number of seeds per ear, while the criteria were rather low, namely: weight per ear. Low criteria are plant height, number of leaves, stem diameter, male flowering age, female flowering age, cob length and number of rows per cob. The highest KKF value is found in the number of seeds per cob, the slightly high criteria are found in the weight per cob and the low criteria are found in plant height, number of leaves, male flowering age, female flowering age, cob length, number of rows per cob. The heritability values of all observed parameters are in the moderate to high range. In the qualitative parameter of seed color there are three colors, namely light purple, purple, and white.
