Genotype X Environment Interaction Analysis of Rice Genotypes under Boro Condition for Yield Contributing Traits

An experiment was conducted using 30 rice genotypes along with standard check (Gautam) in two different dates of sowing for two year to assess their stability in terms of plant height, spikelets per panicle and grain yield in diverse environments during Rabi 2021-22 and 2022-23. The investigation was undertaken at Pusa Farm of Dr. Rajendra Prasad Agricultural University, Pusa, Samastipur, Bihar under open field conditions in randomized block design with two replications. The results showed that the genotypes like RAU 140118115, RAU 14211532573, RAU 14153576951 and Rajendra Saraswati are considered as stable for plant height and spikelets per panicle while for grain yield RAU 1417211517, RAU 1415121743, RAU 141535769534, RAU 141642522, RAU 13972581254, RAU 14171117432, Rasi, Vandana, Boro-3, Rajendra Nilam and Rajendra Laxami was found suitable for average environment and encompasses fair stability and wide adaptation over different environment.
