“…In addition to exhibiting a negative and significant relationship with the number of days to 50% flowering, plant height imposed a strong and positive correlation with the number of tillers per plant, the number of panicles per plant, leaf length, leaf area, kernel width, root fresh weight, root dry weight, and grain yield per plant [11].…”

Thirty-one three-line rice hybrids and three commercial checks were used in the current study for correlation and path coefficient analysis. In Kharif 2021, the experiment was carried out at the TCA Hybrid Rice field in Dholi, Pusa, Bihar, India. The experimental design adopted was a Randomized Complete Block Design (RBD) with three replications that included 18 quantitative attributes. Plant height, number of tillers per plant, number of panicles per plant, leaf length, leaf area, kernel length, kernel width, root fresh weight, root dry weight, spikelet fertility, and test weight showed a positive significant correlation with grain yield per plant. Hence, selection for any one of these characteristics would ultimately bring improvement in grain yield. The traits number of tillers per plant, plant height, root fresh weight, leaf length, no. of panicles per plant, leaf width, kernel length, and root volume revealed a significant direct impact on grain yield per plant. Thus, breeding for these characteristics could end up resulting in a higher grain yield.

“…The phenotypic correlation between the number of panicles per plant and the following variables was significant and positive: panicle length, leaf length, test weight, spikelet fertility, root fresh weight, and root dry weight; on the other hand, there was a negative significant relationship with culm diameter [11,13].…”

Yield component analysis provides a framework for identifying potentially useful traits for yield improvement. A field experiment was conducted for two consecutive years to evaluate the forty four low land traditional rice cultivars for twenty three panicle yield and its attributing traits during kharif season at the Zonal Adaptive Research Station, Krishnagar, Nadia, West Bengal, India. Significant varietal differences were observed for all the characters. Among the panicle yield attributing traits, number of primary branches per panicle, number of grains on primary branches panicle -1 , number of spikelets on primary branches panicle -1 , grain length, grain breadth, grain thickness, kernel breadth, kernel thickness, 100 grain weight, 100 kernel weight correlated significantly and positively with panicle yield both at the genotypic and phenotypic levels. Results of path analysis showed that the direct positive effect on panicle yield was greatest for number of spikelets on secondary branches panicle -1 (0.998) which is followed by number of grains on secondary branches panicle -1 (0.948), grain length (0.755), and number of spikelets on primary branches panicle -1 (0.625), grain thickness (0.392) and fertility % of spikelets on primary branches panicle -1 (0.378). Few characters like number of primary branches panicle , by number of grains on primary branches panicle -1 and grain breadth showed negative direct effect on panicle yield even though the genotypic correlation coefficients on panicle yield were positive. The study revealed that the direct selection of the above said traits might be rewarding for panicle yield improvement since they revealed a true relationship with the panicle yield.
