Abstract

Background: Tillering is one of the yield-determining character in the rice. The growth and development of tillers depend on environment and varietal characteristics. In the same environment varieties of rice differs in producing tillers. In the rice physiology, major part of the population comes from tillers which are developed at the initial tillering period. Therefore, the present study was undertaken to study the tillering pattern of different rice varieties on varying soil textured sites.

Methods: The experimental soil sites were light, medium and heavy textured using four rice varieties viz. PR121, PAU201, PR128 and PR129. Plants of one meter row length (5 hills each from three locations) were selected and marked for tillering counting. Counting was performed at 35, 50 and 65 days after transplanting and at maturity. Tillering rate (TR) = the maximum tiller/tiller duration. Panicle bearing tiller rate (PBTR) = (number of panicle per hill/number of maximum tiller per hill) x 100.Tiller morality = (TL1-TL2/TL1 x 100 where TL1 is the total tiller number at time T1 and TL2 is the total tiller number at time T2. Correlation and regression analysis were performed.

Results: Among the four varieties, PR121 produced maximum effective tillers (11.7 hill-1) whereas PR128 and PR129 were identical (10.3 hill-1) and least (9.3 hill-1) effective tillers have been recorded in PAU 201. The linear regression model (Y = 2.4514 X + 41.03, R2 = 0.31) has been developed for forecasting grain yield of rice using number of effective tillers. Among rice varieties tiller mortality rate was in the order: PR 121 (52.1%) > PR 129 (51.3%) > PR 128 (49.1%) > PAU 201(47.7%). Variety PR 121 performed higher tillering rate (0.49 per hill per day). The yield superiority of variety PR 121 over PR 128, PAU 201 and PR 129 was 3.9, 7.1 and 15.0 respectively. Correlation coefficient between panicle number and maximum tillers was positive.
