Abstract

Litchi bears fruits on panicle and its characteristics significantly affect fruit set and quality of fruits. Weak panicle exhibits very poor fruit set and quality which is one of the major challenges. Therefore, an experiment was conducted to assess the relationship among panicle, fruit set and quality of litchi in 2017 and 2018 at ICAR-National Research Centre on Litchi, Muzaffarpur, Bihar. Ten years old cultivars of litchi Mandaraji, Rose Scented and Seedless Late were selected and experiment was laid out in randomized block design (RBD) with three replications. Results revealed that there was a strong correlation between the length and width of panicle in cultivar Shahi (0.97), China (0.93) and Late Bedana (0.59).The length of panicle was highly and positively correlated with fruit set in cultivar China (0.92), Shahi (0.82) and Late Bedana (0.87). A strong correlation between girth of panicle and fruit set was also observed in Shahi (0.94), Late Bedana (0.81) and China (0.

Conclusion

The length of panicle exerted a positive correlation with width and girth of panicle which has significant role in carrying maximum number of fruits per panicle at harvest. Irrespective of cultivars, length and girth of panicle exerted a positive influence on fruit set. However, in Shahi, length of panicle rather than girth of panicle played a great role in determining fruit set while in Late Bedana, both length and girth of panicle were crucial for fruit set. For genetic improvement in litchi, emphasis should be given on improvement of length and girth of panicle. This study provide insights to litchi breeder in selecting promising genotypes during selection with consideration of panicle length and girth.
