Correlation Coefficient and Path Analysis of Advance Rice Genotypes in Central Mid-hills of Nepal
Journal Title: International Journal of Research in Agricultural Sciences - Year 2018, Vol 5, Issue 3
Abstract
Grain yield being a complex traits, to achieve the basic aim of plant breeders of improving the yielding potential of existing varieties along with creation of new varieties with high yielding potential, this experiment was carried out to study the association of yield attributing characters with grain yield and path analysis in twelve rice genotypes in central mid hills of Nepal.The correlation coefficient analysis revealed the positive and significant association of 1000 grain weight, flag leaf area and SPAD reading with yield while plant height showed negative and non-significant correlation with yield. Path analysis showed flag leaf senescence, 1000 grain weight, flag leaf area and SPAD had positive and high direct effect on grain yield respectively. Hence direct selection of any traits namely flag leaf area, 1000 grain weight and SPAD reading can be effective for future breeding programs to improve yield trait. Improvement in these traits will result in simultaneous improvement of yield.
