| description | The research was conducted with six parental
genotypes: varieties Anno, Gold, Joel, Junior, PF-G1 and
Shawnee with aim to improve the dry pea breeding for
higher grain yield. Objectives of the research were to
investigate: a) the inheritance of grain yield per plant
and its components; b) to determination of the combining
ability of parents and their cross-combinations; c)
the interrelationships among grain yield, its components
and morphological traits; d) choosing the primary selection
criteria; e) choosing the best cross-combinations in
order to achieve the highest selection response of grain
yield; f) simple and digenic epistatic gene-effects in the chosen cross-combinations which determ the trait chosen
as a primary selection criterion; g) the genetic components
of variation in the chosen cross-combinations
of the trait chosen as a primary selection criterion; h)
the anticipation of genetic gain of grain yield per plant
of the chosen cross-combinations. The research was
conducted on experimental fields and laboratories of the
Agricultural Institute Osijek. Parental lines were chosen
in 2006, the first series of crossings in a diallel fashion
were performed in 2007, and the second series in 2008,
in a diallel fashion plus back-crossing. The obtained
generation material (P1, P2, F1, F2, BC1 i BC2) of 15
biparental combinations was seeded in the field trial in
2009. Measurement of the yield, its components and
morfological traits was done at the end of vegetation.
The inheritance of investigated traits was estimated
using Hayman’s approach to diallel analysis, combining
abilities were determined using Griffing’s approach to
diallel analysis, interrelationships among investigated
traits were determined using correlation analysis, the
primary selection criterion was chosen according to
the inheritance of the investigated traits and their interrelationships,
best cross-combinations were chosen
upon Griffing’s analysis results and two principles: a)
the highest per-se value of F1 cross-combination and b)
the highest values of general combining abilities of the
two involved parents. In the chosen cross-combinations,
estimation of genetic effects determining the chosen
trait (yield per plant) was conducted using the generation
mean analysis, and estimation of genetic variance components
was conducted using variances of the six basic
generations. Anticipation of the genetic gain of grain
yield per plant was conducted using estimated genetic
effects and variances in the chosen cross-combinations.
The highest narrow-sense heritability was estimated for
thousand grain weight (82%), followed by plant height
(78%), count of nodes till the first pod (60%), grain yield
per plant (52%), count of pods per plant (40%), and the
least one was estimated for count of grains per plant
(31%). Cross-combination Anno×Joel had the highest
per-se grain yield per plant and highly significant special
combining effect. Very strong positive correlation was
found between grain yield per plant, count of grains per
plant and count of pods per plant. Aiming to increase a
grain yield per plant, the grain yield per plant per-se was
elected as the primary selection criterion due to its appreciable
narrow sence heritability estimation. Anno×Joel
cross-combination was chosen as the most promising
according to the highest per-se value of grain yield per
plant, and Gold×Joel cross-combination according to
the highest values of general combining ability effects
of both parents. Using generation mean analysis there
were estimated small additive genetic effects for grain
yield. On the contrary, there were estimated high values
of additive genetic variance component at six basic generations.
The highest anticipated genetic values of grain
yield of the future recombinant inbred lines that could be
derived from the chosen cross-combinations should surpass
10.91 g/plant, respectively. These would respond to selection gain of maximum of 167 % in relation to the
highest yielding parent Shawnee which had the genetic
value of grain yield per plant of 4.08 g. |
