Title : PERFORMANCE OF LOCAL CHAKHAO (BLACK RICE) GENOTYPES OF MANIPUR THROUGH STUDIES OF CORRELATION AND PATH ANALYSIS.

Abstract :

17 genotypes of Chakhao (black rice) varieties which are found locally in Manipur were evaluated under experimental rice field at Mongsangei, near SSB, Imphal west during two consecutive Kharif seasons of 2019 and 2020. Data were recorded on thirteen quantitative characters and the analysis of variance revealed highly significant for all the traits in both the year and on data pooled over years, indicating the presence of considerable amount of variability among the genotypes. High estimates of GCV and PCV was observed for number of effective tillers per plant, highlighting the presence of wider variability for this character as compared to other characters. High heritability along with high genetic advance were observed for grain yield per plant, number of spikelets per panicle and number of filled spikelets per panicle. Correlation studies showed that Grain yield per plant exhibited significant positive correlation with the characters tillers per plant and effective tillers per plant at both genotypic and phenotypic level. And at the phenotypic level for the characters plant height, number of spikelets per panicle and number of filled spikelets per panicle. For path analysis, the highest direct effect was exhibited by no. of effective tillers per plant followed by no. of days to 50% flowering, no. of filled spikelets per panicle, flag leaf length and plant height in both genotypic and phenotypic level. Highest indirect positive effect was revealed by no. of tillers per plant through no. of effective tillers per plant. Also panicle length, plant height, no. of spikelets per panicle, no. of filled spikelets per panicle and no. of tillers per plant showed high indirect effect through no. of effective tillers per plant in both genotypic and phenotypic level. The study concluded that, Chakhao Poireiton A can be used as a promising genotype since it exhibited high grain yield per plant, high no. of spikelets per panicle, and highest no. of effective tillers per plant.
