Studies of Genetic Parameters for Yield and Yield Attributing Traits of Kodo Millet (Paspalum scrobiculatum L.)

Descriptive statistical analysis and variability studies in germplasm collections of Barnyard Millet (Echinochloa frumentacea L.)

“…This observation was in agreement with the earlier reports of Nirubana et al, 2017, Rinkey et al, 2018and Jyoti et al, 2018 Analysis of genetic variability revealed that peduncle length, grain yield, stem girth, the number of tillers, fodder yield, proline content and flag leaf width established The numbers bolded are the highest and lowest values.…”

“…Seven traits namely, peduncle length, grain yield, stem girth, the number of tillers, fodder yield, proline content, flag leaf width established relatively high GCV value (23.71-49.63%) (Table 4). These results were supported by the findings of Nirubana et al, 2017 andJyoti et al, 2018. Among the nineteen traits considered in the present study, seventeen traits had higher heritability percentage greater than 60%. High heritability was followed with higher genetic advance was recorded for the traits like days to 50% flowering, plant height, flag leaf length, flag leaf width, inflorescence length and panicle breadth, the number of racemes/panicle, peduncle length, length of lower raceme -right, the number of nodes, stem girth, the number of tillers, fodder yield, relative water content, proline and grain yield which implied the predominance of additive gene effects, controlling these traits.…”

“…Very close relationship was found between GCV and PCV for most of the characters revealing the least influence of environment for their expression. Similar results had been reported by Jyoti et al, 2018. Generally the PCV estimates were higher than GCV's as found by Daba (2000) showing that the apparent variation was not only due to genotypes, but also there was influence of environment.…”

“…High heritability was followed with higher genetic advance was recorded for the traits like days to 50% flowering, plant height, flag leaf length, flag leaf width, inflorescence length and panicle breadth, the number of racemes/panicle, peduncle length, length of lower raceme -right, the number of nodes, stem girth, the number of tillers, fodder yield, relative water content, proline and grain yield which implied the predominance of additive gene effects, controlling these traits. Subramanian et al (2010), Karad et al (2013), Nirubana et al, 2017, Jyoti et al, 2018and Vikram et al, 2020 also had found similar findings where in, high heritability coupled with high genetic advance observed for grain yield, dry fodder yield and plant height which was similar to the findings of Prakash and Vanniarajan.(2013). Thus early simple selection could be exercised due to the presence of fixable gene effects.…”

Analyzing the Variability and Correlation in M4 Mutants of Kodo Millet (Paspalum scrobiculatum L.) Grown in Southern India

“…Since, the high heritability in this trait was due to the influence of environment, selection for this trait might not be effective [14]. However, moderate heritability with high genetic advance was attained in number of tillers per plant, which implies that this trait is governed by additive genes and the moderate heritability is put forth by the high environmental effect [15]. Thus, the selection for this trait will be effective in breeding programs.…”
