Genetic, environmental and agro technical influences on lupins at study in Russia and and Ukraine

Genetic, environmental and agro technical influences on lupins  (Lupinus L.) at study in Russia and on the Ukraine 

B.S. Kurlovich et al., 2004

31 accessions of lupins from the collection of N.I. Vavilov’s Institute belonging to 8 species with various origins were tested in different ecological and geographical conditions (in Russia and on the Ukraine) in 1994- 1998 using a common strategy. Two identical plant densities (low and high) were used at both eco-geographical locations. Weather conditions (temperature and a rainfall) were registered also.

The research performed has shown that phenotypic manifestation of yield and other qualitative  characters in lupins include influence of genotype, influence of environment and agriculture, as well as their interactions. The environments are the most important source of variation for all accessions of lupins, explaining from 50.1 % at cv. Ladny, (L. angustifolius) to 68.9 % at k-2770 (L.mutabilis) of the variance in yield. The share of genotypes has varied only from 14.4 % (at k-2770, L.mutabilis) up to 29.7% (at cv. Ladny, L. angustifolius) and has averaged 22.9 % on all studied accessions. Miscellaneous accessions differ in the scale of influence of various factors. Eco-geographical studies have revealed genotypes with a high enough stability of different characters (cvs. Ladny, Timir-1 and Line -7 at L. angustifolius; cvs. Juno, Neutral and BSChA-382 at L.luteus; cv. Tambov early at L. albus and the accession of L. ornatus Dougl.(k-3011). The variation coefficient (v) has not been higher than 10 % in these cultivars. But we fixed a negative correlation between high productivity and stability (r = -0.648). The most highly productive appeared to be cvs. Frost, Welikan – 6, Nemchinov. Blue and Welikan – 4 at L. angustifolius; accession 41B from Portugal, cvs. Juno and Industrial at L. luteus; accessions k-3023 from Brazil, k-3046 from Marokko, and cv. Soz at L. albus; accession k-2770 in L. mutabilis. Cv. Juno from Poland (L. luteus L.) is selected among the investigated accessions. It has a high enough stability of yield (v=6.3%) and high productivity of seed (9.39 ±3.90 g/plant) and mass of all plant (30.03 ±7.10 g/plant). Averaging across years, locations and densities provide very valuable information about influences of genotype, environment and agro technical conditions on different accessions of lupins.

The information gained from these trials can be used to assess the stability of genotypes across a range of environments and may disclose the presence of different genotype - environment and other interactions within various accessions of lupins.
