SUNIL CHAUDHARI, S.B. PATIL, DIPALI THAKARE, A.N. TIKLE and K.B. SAXENA. 2017. Effect of fertility restoration on yield and its contributing traits of CGMS-based pigeonpea hybrids. Green Farming Vol. 8 (2) : 287-290 ; March-April, 2017

ABSTRACT
Ten CGMS-based hybrids were evaluated under net condition to avoid natural out-crossing and to check the real effect of fertility restoration on yield and its contributing traits. Five out of 10 hybrids had complete fertility restoration while two hybrids, ICPH 3494 (31.6 %) and ICPH 3491 (35.3 %) had a partial fertility restoration with a minimum number of pods per plant. It was noticed that incomplete fertility restoration led to a less number of pod set and as a consequence, maturity of those hybrids got extended due to insufficient pod load. A significant positive correlation was observed among fertility restoration, number of pods plant-1 and grain yield plant-1, whereas it was negatively correlated with days to maturity further confirms that the fertility restoration does significantly influence pod set, days to maturity and yield of hybrids. The hybrids ICPH 2671 (70 g & 53.9 %) followed by ICPH 3461 (64.2 g & 41.1 %) and ICPH 2751 (62.0 g & 37.6 %) recorded higher yield per plant and economic heterosis in comparison to other hybrids and commercial check (Asha).
