Abstract

Current research was conducted to analyze the coefficient and distribution of direct and indirect influence of yield components and earliness characteristics in wheat genotypes. Both experiments were carried out at the Pot House of the (NIA Nuclear Institute of Agriculture, Tandojam) (Latitude: 25.433. Longitude: 68.533), the experiment was established as a randomized complete block design (RCBD). There were six varieties of wheat, namely IBWSN1010, IBWSN 1025, TD1, ESW9525 Chakwal86 and Khirman, which were used to study the correlation coefficient between morphological and physiological traits. The study was based on fifteen (15) morphologically and physiologically traits that were observed. The analysis of variance showed significant differences between the characteristics of the varieties. The ESW9525 showed better performance for all morphological and physiological traits. The correlation and the coefficient analysis showed that the days to maturity and the days to growth predicted significant positive predictions related to the height of the plant (cm) and the length of the ear. Days to 75% heading and days to 75% maturity showed negative and positive effects for osmotic potential, relative water content in% and total chlorophyll content in%. Plant height (cm) had negative and positive and significant with tiller plant-1. Therefore, in our research trial, variety ESW9525 may be favorable for hybridization in order to produce a promising and drought tolerant wheat cultivar

Highlights

Non-significant correlations were observed with grain weight (r= 0.056ns), straw weight (r= 0.101ns), whereas non-significant and negative correlations were observed between seed index (r= -0.040ns)
Days to 75% maturity: Days to 75% maturity showed significant and positive correlations with plant height (r=-0.005*), tillers plant-1(r= 0.187*), spike length (0.181*) non-significant and positive correlations were observed with grain weight r= (0.290ns), straw weight (r= 0.183ns), seed index (r= 0.129ns)
The results showed that the days to maturity and the days to growth predicted a significantly positive association with the height of the plant and the length of the ear. (Nemat et al, 2015), predicted a significant and positive correlation, which reflects that plant height and ear length will eventually increase with increasing days of sprouting and maturity

Summary

Introduction

Physiological traits were observed nonsignificant and negative correlations with proline (r= 0.013ns), osmotic potential (r= -0.131ns), potassium content (r= -0.127ns), glycine-betaine (r=-0.072ns), total soluble sugars (r=- 0.131ns), whereas nitrate reeducates Physiological traits showed significant and negative correlations with proline content (r=-0.294*), osmotic potential (r= -0.479*), potassium content (r= -0.332*), glycine-betaine (r= -0.256*), total soluble sugars (r= -0.285*) and nitrate reeducates activity (r= -0.038ns).
