Abstract

Aims: The objectives of the research work were to evaluate the morpho-physiological characteristics of selected local and high yielding varieties (HYV) of rice.  Study Design: The research used randomized complete block design (RCBD) with four replications. Place and Duration of Study: Central research field of Sher-e-Bangla Agricultural University, Dhaka-1207 during June to December 2017. Methodology: In this research we used seven conventional rice cultivars (Kanchancni, Chinisagar, Sunashail, Ranjay, Lohadang, Haldijan, Kohabinni) and three high yielding rice varieties (BR11, BRRI dhan46 and BRRI dhan51) where different morpho-physiological data were taken for evaluation their performance. Obtaining data were analyzed by using analysis of variance technique and subsequently, least significance difference (LSD at 5%) for comparing the treatment means by MSTAT-C software. Results: The morpho-physiological characters showed the considerable variation during the experimentation. Among the different growth parameter, the highest plant height and flag leaf area was found from Lohadang, number of leaves hill-1 and number of tillers hill-1 from Ranjay, crop growth rate and absolute grain growth rate from Sunashail, flag leaf dry weight from Kanchancni and SPAD value of flag leaf and specific leaf weight from BRRI dhan51. Meanwhile, the minimum days to anthesis, days from anthesis to maturity and life duration from germination to maturity were recorded from BRRI dhan46 and Kanchancni, respectively. Conclusions: The results showed that among the conventional rice cultivars Kanchancni and the HYV varieties, BRRI dhan46 exhibit better morpho-physiological performance than others.

Conventional rice cultivars hybrid rice crop growth rate absolute grain growth rate SPAD value specific leaf weight.
