Evaluation of bread wheat genotypes for yield and its associated traits
Abstract
Wheat (Triticum aestivum L.) is the most widely adapted crop to various agro climatic conditions, consequently, has got a major place among the cereal crops in the world. In wheat development programs, the evaluation and identification of superior lines from introduced plant materials, is the first and leading step in a crop improvement program. The experiment was planted at Mountain Agricultural Research Center, Juglot, Pakistan during 2014-15 following randomized complete block design with three replications. The current research was carried out to evaluate 10 bread wheat accessions for yield and its associated characters. The analysis of variance, mean performance, correlation and cluster analysis were computed. The analysis of variance exhibited that all the genotypes performed significantly (P≤0.05) variable for plant height, days to flowering, days to 50% maturity, grain per spike, straw weight, Total grain weight, registering the significant genetic variability among the genotypes for further evaluation. With regards to mean performance, the AC-4, AC-6 and AC-8 showed better performance for various traits. Cluster analysis revealed two accessions AC-4 and AC-5 as most diverse among all members. So, these accessions can be further used in breeding programme to achieve better yield. Also molecular studies on these accessions can point out many novel gene sources in these accessions.
