Assessment of Finger Millet Virescent Lines for Yield and Yield Related Traits using Top Cross Method
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 4
Abstract
An experiment was conducted to assess nineteen finger millet virescent lines derived from cross [GPU 28 x (GE 1 x GPU 67)8-5] for seven yield and its attributing traits by following top cross method, where Indaf 9 was used as a tester. The virescent lines along with their top cross progenies and checks (GPU 28, GE 1, GPU 67 and Indaf 9) were evaluated under augmented design. Based on breeding value, per se mean and topcross progeny mean value virescent lines were selected for high grain yield per plant (7-1, 4-1 and 17-6), high fodder weight per plant (12-10, 4-1 and 4-11), more finger numbers per ear head (12-10, 8-3 and 17-6), longer finger length (4-11, 18-2 and 11-6) and reduced flowering time (3-6, 5-2, 8-3, 18-2, 12-4, 4-11, 4-2 and 21-6). Parent-offspring correlation coefficient (rPO) was calculated to ascertain the relationship between parent and offspring, which was found significant for plant height, finger length, finger number, fodder weight per plant and grain yield per plant. Regression of breeding value (A) over phenotypic value (P) (bAP), which is analogous to heritability was high for finger length (0.84 ± 0.1), productive tillers (0.53 ± 0.1) and finger number per ear (0.5 ± 0.14) and low for fodder weight (0.03 ± 2.71) and grain yield (0.09 ± 0.7).
