Mango panicle parameters: Comparative study and assessment of weather parameters effect

Abstract

the year 2019-20 and 2020-21 to study the mango panicle characteristics and correlation between panicle growth parameters and climatic parameters. This study was conducted on seven mango varieties viz., Sonpari, Alphonso, Amrapali, Kesar, Dashehari, Totapuri and Rajapuri. Kesar recorded maximum length of panicle (37.55 cm) which was at par with Alphanso (35.66 cm) and Amrapali (32.80 cm). The maximum width of panicle (22.76 cm) was recorded in Kesar which was at par with Rajapuri (19.63 cm). Mango cv. Alphonso recorded maximum diameter of primary rachis (5.65 mm), which was at par with -1 Kesar (5.60 mm) and Rajapuri (5.18 mm). Maximum numbers of spikelets panicle (above 10 cm) were recorded in cv. Kesar (14.00), which was at par with Alphonso (10.95). In correlation study it was noticed that , during the year 2020-21 panicle breadth was significantly positive correlated with minimum relative humidity (r = 0.85*) and total rainfall (r = 0.81*). During the year 2019-20, it was observed that, correlation between diameter of primary rachis and climatic parameters viz., maximum temperature (r= -0.81*), minimum temperature (r= -0.92**) and bright sunshine hours (r= -0.91**) were significant and negatively correlated.
