Abstract

 THE OBJECTIVE OF THIS RESEARCH WAS TO DETERMINE FORAGE YIELD AND QUALITY AMONG NATIVE ALFALFA ECOTYPES. CORRELATIONS BETWEEN THE INVESTIGATED TRAITS WERE ALSO ANALYZED, SINCE DATA ON RELATIONSHIPS ARE OF GREAT IMPORTANCE IN SELECTION, ESPECIALLY IN TRAITS WITH LOW GENETIC VARIABILITY. EXPERIMENTAL MATERIAL CONSISTED OF 13 ALFALFA GERMPLASMS. INVESTIGATION WAS CARRIED OUT DURING A THREE-YEAR PERIOD. THE FIELD TRIAL WAS ARRANGED ACCORDING TO THE RANDOMIZED BLOCK DESIGN WITH FOUR REPLICATIONS. THERE WAS A STATISTICALLY SIGNIFICANT DIFFERENCE OF PLANT HEIGHT FROM 74.50 CM (MOAPA) TO 96.00 (ALHORD), OF NUMBER OF INTERNODES FROM 12.75 (KHOSROVANAGH) TO 16.00 (MOAPA), OF LEAF SIZE FROM 0.45(RANGER) TO 1.0125 (LEGHLAN), OF LEAF FRESH WEIGHT TO STEM FRESH WEIGHT RATIO (LFW/SFW) FROM 0.4400 (LEGHLAN) TO 0.5400 (MOAPA), LEAF DRY WEIGHT TO STEM DRY WEIGHT RATIO (LFW/SFW) FROM 0.3725 (LEGHLAN) TO 0.4750 (MOAPA),OF IN VITRO DRY MATTER DIGESTIBILITY (IVDMD) FROM 45.42%(GARA-YONJEH) TO 50.67% (BAFTAN), OF ACID DETERGENT FIBER (ADF) FROM 38.83% (KHAJE) TO 44.70% (GARA-YONJEH), OF CRUDE FIBER (CF) FROM 25.96%(SIVAN) TO 32.48%(RANGER) AND OF NEUTRAL DETERGENT FIBER (NDF) FROM 47.03% (KHAJE) TO 57.43% (MOAPA). THERE WERE POSITIVE CORRELATIONS BETWEEN PLANT FRESH YIELD, DRY YIELD, NUMBER OF STEMS AND PLANT HEIGHT. LFW/SFW AND LDW/SDW DIDN'T SHOW ANY SIGNIFICANT CORRELATION WITH QUALITY COMPONENTS (IVDMD, CP, ADF, CF AND NDF). THERE WAS A NEGATIVE CORRELATION BETWEEN CP AND CF. SIVAN, DIZAJ-SAFARALI, GARA-BABA, KHOSROVANAGH AND KHAJE ECOTYPES HAD THE BEST QUALITY AND ALHORD AND LEGHLAN ECOTYPES WERE BELONGED TO THE SIMILAR GROUP. THEY CAN BE RECOMMENDED AND CONSIDER TO IMPROVE SOME SYNTHETIC VARIETIES.
