Stability for Yield and Maturity in Mash (Vigna Mungo (L.) Hepper)

Fourteen varieties of Vigna mungo, HPU-392, HPU-394, HPU-410, HPU-402, HPU-384, HPBU-9, HPBU-52, PDU-1, Pant U-19, UH-2, UH-27, UH-42, UH-45 and T-9, were studied for stability parameters with respect to yield and autarky. Genotype × environment interaction was significant for both characters. Linear and nonlinear components were predominant in genotype × environment (G × E) interaction in case of yield, whereas linear component accounted lor most of G × E interactions for maturity. HPBU-9 was the most stable genotype with respect to yield, while UH-2 and UH-42 were highly stable for maturity. No correlation among the three stability parameters was observed for both characters. It is proposed to consider all the three parameters while breeding stable varieties of mash.
