ABSTRACT
This study was carried out during the two winter seasons of
2019/2020 and 2020/2021 to study the type of gene action controlling some
economic characters in garden pea (Pisum sativum L.) using six genotypes
by hybridized in a half diallel model. Genotypes (parents and F1 crosses)
were grown in randomized complete block design with three replications to
estimate general combining ability effects of the parents and specific
combining ability effects of crosses, heterosis as deviation from mid and
better parent and potence ratio for some economic characters, viz., plant
height, number of days to flowering, number of branches/plant, number of
seeds/pod, number of pods/node, pod length, pod weight, 10- green seeds
weight and shelling percentage. Results indicated that all studied traits
showed significant mid parent and better parent heterosis in desirable
direction in some crosses except the better parent heterosis for number of
seeds/pod trait. Also, all studied traits exhibited different types of potence
ratio.
