Abstract:
High production and good quality are always the principal goals for agriculturally important crops, without the exception of mushrooms. P. pulmonarius is one of the commercially important edible mushrooms throughout the world. The present study was designed to improve the potential of P. pulmonarius LAU 09 for yields production. The improvement of P. pulmonarius LAU 09 was carried out by UV light exposure at 210 nm for 3 h, at 30 min interval. The highest rate of spawn ramification (0.889 cm day-1) and percentage spawn productivity (47.64%) was obtained by LAU 90. The primordia of mushroom sporophore recorded at 11th day of cultivation by LAU 60 and LAU 90 while recorded on 15th day in LAU 09. The highest biological efficiency (97.57%) and production rate (3.9%) obtained by LAU 90 while the least of 41.43 and 1.34%, respectively was obtained by LAU 09. The morphological and molecular characterization of the mutant strains established their true variation from their wild type. The wider evolutionary lineages of LAU 60 (mutant) from LAU 09 (wild) was shown, with LAU 09 located at outgroup root of phylogenetic tree and LAU 60 formed a phylogenetic cluster with another strains of P. pulmonarius (AY450349) from GenBank database, supported with 85% bootstrap value, while LAU 90 (mutant) match no strain at GenBank database collection. The result obtained shows the improved performance of the mutant strains over the wild (parent) strains, especially the mutant at 90 min exposure (LAU 90).
