Principal component analysis of foxtail millet accessions under rainfed condition
DOI:10.37992/2024.1502.044
Abstract
Foxtail millet (Setaria italica (L.) Beauv) is one of the earliest cultivated millet for grain, hay and silage. There is wide genetic diversity available in foxtail millet and characterization of available germplasm is a pre-requisite for the genetic improvement of any crop. Keeping the above fact in view 30 foxtail germplasm lines were evaluated during kharif 2020 and 2021 for morphological traits, stover yield, dry fodder yield and seed yield under rainfed conditions of Haryana. The results (based on pooled data of two years) revealed that enough variability was present among germplasm lines for further exploitation. High heritability and positive correlation was reported between traits like plant height, leaf length, leaf stem ratio, stover yield, grain yield etc. Principal component analysis also revealed that PC1, PC2, PC3, PC4 and PC5 contributed for 31.8%, 15.05%, 12.31%, 11.43% and 10.14%, respectively to the total variation. Five foxtail accessions viz., SEA8, SEA12, SEA48, SEJ184 and SEA37 were identified promising for yield and related traits under rainfed conditions of Haryana.
