“…Analysis of variance revealed significant differences among the genotypes for all the 13 quantitative characters indicating the presence of considerable genetic variation in the experimental material ( Among the traits, the highest value of GCV was registered for thumb raceme length (35.61%), number of productive tillers per plant (26.58%), length of panicle (22.79%) and grain yield per plant (20.47%) suggesting that these characters are under the influence of genetic control (Table 4). These results are in accordance with Keerthana et al (2019).…”

The present investigation was undertaken to assess genetic diversity in seventy genotypes of kodo millet. The analysis of variance revealed the presence of significant variation among the genotypes for all 13 characters. Higher genotypic coefficient of variation (GCV), phenotypic coefficient of variation (PCV), heritability and genetic advance as per cent mean were recorded for thumb raceme length, number of productive tillers per plant, length of panicle, raceme length and grain yield per plant, indicating that simple selection could be practised for improving these traits. Seventy genotypes were grouped into seven different clusters on the basis of magnitude of D 2 values by Mahalanobis D 2 analysis. Cluster I had 51 genotypes followed by cluster II with 14 genotypes, while clusters III, IV, V, VI and VII were mono genotypic. The inter-cluster distance was high between clusters II and III and therefore it is suggested to use these genotypes as parents for hybridization to evolve potential segregants.

“…High PCV and GCV was expressed by the traits such as Na + /K + ratio (59.33%, 57.66%), grain yield per plant (31.11%, 30.54%), number of grains per panicle (28.59%, 28.54%), number of productive tillers per plant (23.75%, 22.99%) and 1000 grain weight (23.20%, 23.07%). Similar findings were reported by Dhakal et al, (2020) for number of productive tillers per plant, Kumar et al, (2020) for number of grains per panicle and Devi et al, (2020) for 1000 grain weight and grain yield per plant and Keerthana et al, (2019) for Na + /K + ratio.…”

“…These results were in accordance with Vijayalakshmi et al (2014) in finger millet genotypes and Vieira et al (2018) in soybean cultivars which were screened for salt stress under greenhouse condition. The genotypes that recorded higher grain yield per plant and lower Na + /K + ratio can be considered sodicity tolerant, as the Na + /K + ratio has a significant negative correlation (-0.8128) with grain yield (Keerthana et al, 2019). These tolerant genotypes have the ability to maintain the level of K and lower Na accumulation in their shoots (Sharma et al, 1986).…”

Sodicity affects a larger area than salinity, but research on the sodicity tolerance mechanism is limited. The study was carried out to screen 120 finger millet genotypes under sodic soil conditions and identify sodicity-tolerant genotypes. The experimental field soil conditions were sandy clay loam with pH 8.9, electrical conductivity (EC) 0.94 dSm-1 and exchangeable sodium percentage (ESP) 21.5, which was naturally sodic. Grain yield per plant and Na+/K+ ratio were recorded for each genotype to screen sodicity tolerance among the genotypes. A significantly higher grain yield per plant than that of the sodicity-tolerant check variety TRY 1 (23.10 g) was observed in 30 finger millet genotypes. The analysis of sodium and potassium revealed that these 30 finger millet genotypes also recorded a significantly lower Na+/K+ ratio, which is comparatively lower than that of the sodicity-tolerant check variety TRY 1 (0.23 Na+/K+ ratio). The genotypes (FIN 3045, FIN 2875, FIN 3077, FIN 3015, FIN 3063, FIN 2861, FIN 3028, FIN 2867, FIN 2854, FIN 2860, FIN 2872, FIN 2896, FIN 4268, FIN 3034, FIN 3928, FIN 3104, FIN 3965, FIN 3091, FIN 2960, FIN 3994, FIN 4198, FIN 3174, FIN 3078, FIN 4288, FIN 4202, FIN 4238, FIN 3089, FIN 4205, FIN 3966 and FIN 3182) that recorded higher grain yield per plant and lower Na+/K+ ratio can be considered sodicity tolerant. These genotypes with a high grain yield per plant and a low Na+/K+ ratio could be utilized in stress breeding programs to develop sodicity-tolerant finger millet varieties.
