10. Comparative evaluation of linseed varieties under environmental conditions of Tandojam Pakistan
Main Article Content
Abstract
Variability and genetic diversity assessment is foremost activity to be embarked before any crop improvement programme. Divergence analysis is helpful in identifying suitable and diverse parents for realizing high heterotic effects with transgressive sergeants in later generations. Thus, a research study was design to study and the purpose of this study remained to evaluate the variation in seed germination, days taken to flowering and maturity, height of the plant, branches and capsules per plant, thousand grains weight, oil content percentage and seed yield kg per hector at Oilseeds Section, Agriculture Research Institute, Tandojam Pakistan. Six linseed varieties (including candidates and one commercial variety), viz., Pr-83, 84, 102, 17, 75 respectively and Ilsi-90 as check were evaluated for their growth, seed yield and oil yield performance. The field experiment was set up in Randomized Complete Block Design with three replications.The achieved results pointed out that except seed germination, all the growth and seed yield related traits as well as oil content differed significantly (P<0.05) in diverse linseed varieties. It was concluded that linseed candidate varieties Pr-75 and Pr-17 surpassed commercial linseed variety Ilsi-90 (check) in all the growth and seed yield works as well as in oil content, which is a most significant consequence of this experiment, and the varieties Pr-75 and Pr-17 could be promising for general cultivation in Sindh province.
