Variability of adaptive F3 generation wheat in the lowlands

Abstract

Wheat is a cereal crop that has the potential to be developed in Indonesia. Wheat development is directed towards medium to lowland areas. This research aims to evaluate genetic diversity and identify individuals that are adaptive in the lowlands. This research will be carried out from September to November 2024 at the Experimental Garden (KP) of the Faculty of Agriculture, Andalas University. This research uses a survey method with individual observations. The F3 genotypes used were Guri6/Nias and Guri4/Dewata, genotypes Guri 4, and Guri 6 Unand. Observations were made on qualitative and quantitative characters. The research results showed that there were 25 segregants from the F3 Guri 6/Nias genotype and 16 segregants from the Guri 4/Dewata genotype that could grow and successfully enter the generative phase. There were no variations in the characteristics of leaf color, leaf ears and leaf tongues as well as growth type in each F3 population. Plant height is a quantitative characteristic, that is, it has the greatest variation of 110.02 cm and an average value of 40.73 cm.
