Producing promising pea lines through re-selection for yield and quality from master b cultivar

الملخص EN

This investigation was conducted at Barrage Station (BHRS), Horticultural Research, Kalubia Governorate, Egypt, to get some new and promising pea lines (Pisum sativum L.) using pure line selection method on the basis of genetic variability.

Selection was performed between or within four pea populations of Master B cultivar.

The populations were collected from four different regions in Egypt and subjected to selection procedure during 2012/2013, 2013/2014 and 2014/2015 growing seasons.

The investigation intended to study different traits of growth and yield and its components viz., No.

of days to flowering, No.

of first flowering node, plant length, No.

of branches per plant, pod length, pod width, pod thickness, pod weight, No.

of seeds per pod, weight of seeds per pod, No.

of pods per plant, weight of 100 seeds, shelling percentage, pod yield per plant and seed yield per plant.

The target of this study was to improve pea yield and its components as well as earliness of yielding.

The analysis of variance revealed highly significant differences among genotypes for most of the studied characteristics, indicating ample scope of selection.

Most characteristics showed a higher heritability coupled with higher genetic advance through two cycles of selection indicating that these characteristics are stable and can be improved through selection based on phenotypic observations.

Twenty lines were obtained from selection program and were compared against the baseline populations in addition to check cultivar (Entsar1).

Results showed significant differences
