Abstract/ Executive Summary:

An experiment was conducted to evaluate the performance of local aromatic rice cultivars viz. Kalijira, Khaskani, Kachra, Raniselute, Morichsail and Badshabhog. The rice cultivars varied considerably in terms of crop growth characteristics as well as yield and yield contributing characters. The highest plant height (116.00 cm) was found in the variety Morichsail and the lowest in the variety Khaskani. Number of filled grains panicle^-¹ was found highest (100) with the variety Khaskani and the lowest was recorded in the variety Raniselute. Raniselute produced the highest 1000-grain weight (32.09 g) and the lowest (13.32 g) was recorded from the variety Kalijira. The variety Morichsail produced the highest grain yield (2.53 t ha^-1) followed byKachra (2.41 t ha^-1), Raniselute (2.13 t ha^-1) and Badshabhog (2.09 t ha^-1) and the lowest grain yield (1.80 t ha^-1) was obtained from Kalijira. The results of various characters studied in the experiments suggested that some good characters exist in local aromatic rice cultivars which can be exploited through breeding.

End Date: 00-12-2006

Program Area: Variety and Species

Commodity: Rice

Objectives:

The present study was undertaken to explore the yielding ability of six indigenous aromatic rice cultivars.

Methodology:

The experiment was conducted at the Field Laboratory of Agrotechnology Discipline, Khulna University, Khulna during the Aman season of 2006 with six indigenous aromatic rice cultivars namely Kalijira (V1), Khaskani (V2), Kachra (V3), Raniselute (V4), Morichsail (V5) and Badshabhog (V6) as six treatments following Randomized Complete Block Design with three replications. Data collection: Data were collected on different growth parameters such as plant height, tiller number and dry matter accumulation and yield contributing characters viz.number of effective tillers per hill, length of panicle, number of grains per panicle, 1000–grain weight, grain yield, straw yield, biological yield, harvest index and grain weight. Statistical analysis: The data were analyzed by MSTAT–C program and treatment means were compared using Duncan’s Multiple Range Test. Functional relationships were determined among different growth and yield parameters using simple regression analysis.

Achievement/Findings:

From the above findings, it can be concluded that variation exists in different growth parameters and yield and yield contributing characters of selected aromatic rice cultivars. The variety Morichsail produced the highest grain yield compared to others which can be exploited through breeding.
