RATING YIELD AND STABILITY OF PROSPECTIVE LINES WINTER COMMON WHEAT

Zlatina Uhr

Abstract


The test was carried in the period 2012-2014 year in block method in three repetitions with the size of the testplod 10 m2. It was used the adopted in IPGR - Sadovo technology for growing winter common wheat. In experiment were tested fourteen lines obtained by the method of the variety hybridization. In the experiment involved two standard variety Sadovo 1 and Enola. used in Executive Agency for Variety Testing. We have used analysis of variance (Lidanski 1988, Shanin 1977). The yield stability was assessed by Shukla (1972), Wricke (1962) and Kang (1993). And in the three years of the study as the highest yield are expressed MH 270-24, MH 270-24 and MH 268-1008. Through the analysis of variance in terms of yield (Table. 2) found that the genotype has the most influence on this indicator - 71.3%. The interaction genotype x years is significant and his power of influence on yield is 21,7%. The stability of yield in years, defined as the most valuable the lines M H 268-1008, MH 270‑86, MH 270-50, MH 270-24 and MH 270-27.
