Per se performance of matromorphic progenies (Mat3) and their parental lines in garden pea (Pisum sativum L.) under subtropical conditions of J&K

Abstract

Matromorphs or maternals are non-hybrid diploid offspring
which originate entirely from the maternal parent and
facilitate in obtaining instant homozygous lines from
heterozygous base population thereby, shortening the time
requirement of conventional breeding method for the
production of homozygous lines. Per se performance of
twelve advanced generations of matromorphs (Mat3) along
with their ten parental lines were evaluated for growth, yield
and screening against powdery mildew and rust disease
under sub tropical conditions of Jammu & Kashmir under
the present study. A field experiment was carried out during
the year 2020-2021 at the Experimental farm, SKUASTChatha,
Jammu. On the basis of overall findings of the present
research study, it was concluded that Palam Triloki was the
earliest with minimum days to 50% flowering (44.00) followed
by three matromorphic progenies viz., Palam Triloki (46.33
days), Palam Triloki x P-89 (44.67 days) and Palam Triloki x
AP-1 (46.83 days). Regarding plant height, maximum plant
height was recorded in parental line Arka Apoorva (90 cm)
followed by Arka Ajit (89.50 cm) and Arka Apoorva x AP-1
(Pl.1) (88.50 cm) and Arka Apoorva x AP-1(Pl.2) (88.30 cm)
amongst Mat3 progenies were found to be superior. Among
Mat3, maximum number of seeds per pod were recorded in
Arka Apoorva X P-89 (7.83) followed by Arka Apoorva x
AP-1[Pl.2] (6.77) and P-89 (7.18) and Arka Apoorva (6.34)
among parents. Maximum number of pod per plant were
recorded in matromorphic progenies, Arka Apoorva x P-89
(45.89) followed by Arka Apoorva x AP-1[Pl.2] (44.61), Arka
Apoorva x AP-1[Pl.1] (41.83) and among parental lines, P-89
(41.28), Arka Apoorva (35.83) had maximum number of pod.
Maximum pod yield per plant was recorded in Arka Apoorva
x P-89 (200.38g) followed by Arka Apoorva x AP-1 [Pl.1]
(184.37 g) in Mat3 whereas among parental lines maximum

pod yield was recorded in P-89 (174.76g) and Arka Apoorva
(145.72g). Based on the screening of genotypes under study,
Arka Apoorva x P-89 (Mat3) was identified as highly resistant
genotype against major pea diseases i.e. powdery mildew
and rust.
