Impact of the semi-leafless field pea on dry matter yield

Abstract

The field pea breeding at the Agricultural Institute Osijek has primarily been aimed at continued development of new cultivar types with high yield, potential early group maturity and resistance to lodging. Letin is a new semi-leafless -winter field pea (Pisum sativum) with purple flowers and a mottled light brown seed coat. Semileafless and leafed genotypes were evaluated for plant height, lodging, maturity, forage yield and quality in two locations. The forage yield of pea genotypes has an average of 32.21 t*ha -1 . Higher yield was obtained from semi-leafless genotype (34.48 t*ha -1 ). The leafed genotype has achieved better nutritive characteristics. The obtained results point to a need for new tests and the possible introduction of semileafless cultivars in the production as a pea-cereal mixture or as pure crops to be utilized by cutting.KEYWORD: field pea, semi-leafless, yield, lodging SAŽETAKOplemenjivački rad na poljskom grašku na Poljoprivrednom institutu Osijek prvenstveno je usmjeren na stvaranje i razvoj novih tipova kultivara s visokim potencijalom prinosa, rane grupe zrelosti i tolerantnosti na polijeganje. Letin je novi bezlisni tip ozimog poljskog graška (Pisum sativum) s tamnocrvenim cvijetom i šarene svijetlo smeñe sjemene ovojnice. Bezlisni i lisni genotipovi ispitani su na visinu biljaka, rezultate polijeganja, zrelost, prinos zelene mase i kvalitetu na dva lokaliteta. Prinos mase testiranih genotipova graška u prosjeku je iznosio 32,21 t*ha -1 , veći prinos dobiven je s bezlisnim genotipom (34,48 t*ha -1 ). Lisni genotip ostvario je bolje nutritivne vrijednosti. Dobiveni rezultati ukazuju na potrebu za novim testiranjima te moguće uvoñenje bezlisnih kultivara u proizvodnju kao mješavinu grašak-žitarice ili čistih kultura za košnju.

Agronomic performance of normal‐leafed and semi‐leafless pea (Pisum sativum L.) genotypes

“…The results are contradictory: when studying six field pea genotypes (two semi-leafless and four normal-leafed) in eight environments for dry matter and seed yield, Acikgoz et al (2009) concluded that the semi-leafless cultivars newly registered at that time in Turkey had a significant 6% seed yield advantage over the normal-leafed genotypes. Studies by Cupic et al (2013) illustrated that normal-leafed pea cultivars had a lower forage and dry matter yield but higher protein content, though these results were not consistent over different seasons. Narits (2008) reported that semi-leafless cultivars had a higher seed yield (cited in Olle, 2017a), but this was not evident in the investigation of Olle (2017b).…”
