Abstract:

The experimental field was laid in pooled RBD design replicated trice with 30 advanced breeding lines of rice, quality check BPT-5204 (SP-351, SP-352, SP-353, SP-354, SP-355, SP-356, SP-357, SP-358, SP-359, SP-360, SP-70, SP-72, SP-63, SP-61, SP-69, SP-55, SP-80, SP-25, SP-13, IR-64, SP-03, SP-02, SP-34, SP-37, NDR-359, BPT-5204, SP-08, JAYA, SP-75 and SP-57). Physiological parameters were measured at periodical intervals active tillering, panicle initiation, physiological maturity and harvest viz., leaf area index, leaf area duration and crop growth rate. Significant difference was recorded among the advanced breeding lines for leaf area index in both the seasons as well as in pooled data. The genotype SP-08 and SP-72 showed maximum LAI, LAD and CGR compared to quality check BPT-5204. While, IR-64 showed minimum during the flowering stage in first season. In second season genotype SP-08 and SP-72 showed maximum value compared to quality check BPT-5204. While, IR-64 showed the minimum during active tillering stage. Pooled data revealed that the genotypes SP-08 and SP-72 recorded maximum LAI (4.04), LAD (61days) and CGR (24.64 g m-2 day-1) compared to quality check BPT-5204. While IR-64 recorded minimum respectively. The range of leaf area duration 45-77days.
