Genetic variability studies for yield and yield components in 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.…”

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.…”

“…Similar results had been recorded by Chidambaram and Palanisamy (1996), Nirmalakumari and Vetriventhan. (2010) and Nirubana et al, 2017 for grain yield. High PCV was also recorded for traits like the number of racemes/panicle and panicle breadth, fodder yield, proline content and peduncle length.…”

Genetic diversity studies in kodo millet (Paspalum scrobiculatum L.)

“…People have come across the importance of kodo millet and hence its demand is increasing. To fulfill the demand of kodo millet in future, extensive research is needed (Nirubana et al, 2017). Therefore, the present study is conducted to analyse the genetic variability and diversity among 70 genotypes of Kodo millet.…”
