Title : Estimation of Ranking in Bottle gourd (Lagenaria siceraria (Mol.) Standl.) Genotypes over Diverse Environmental Conditions in Humid and Sub-humid Southern Plains of Rajasthan (India)

Abstract :

Vegetables are an important part of a well-nutritious human diet, as well as a key component in achieving nutritional security by providing nutrients, vitamins, and minerals. The plants grow in the humid and sub-humid southern plains of Rajasthan that provides high recompense to growers. Production of bottle gourd is limited due to lack of high-yielding as well as better adaptive cultivars. In order to identify high yielding stable genotypes across the diverse environmental conditions, we have evaluated fifty-eight genotypes of bottle gourd in a Completely Randomized Block Design over three different environments in Rajasthan during summer and late Kharif 2021. According to the Eberhart and Russell model for stability analysis, P1 x P6, P1 x P2, P5 x P6 (bi>1) and P1 x P3, P2 x P5 and P3 x P9 (bi<1) were identified as the most promising genotypes for days to anthesis of first male flower, P5 x P6 and P3 x P8 (bi>1) and P1 x P2 and P4 x P5 (bi<1) for days to anthesis of first female flower whereas P5 x P7 and P7 x P8 (bi>1) and P1 x P3, P2 x P8 (bi<1) for number of branches per plant. P8 x P10, P1 x P2, P6 x P10, P5 x P10 (bi<1) and P4 x P8 and P6 x P7 (bi>1) can be used to increase the leaf area index, whereas, P1 x P6, P6 x P9, P6 x P10 (bi<1) and P2 x P8 and P4 x P9 (bi>1) for fruit diameter and P6 x P9 and P1 x P3(bi<1) and P2 x P8, P8 x P10 and P5 x P9 (bi>1) for fruit weight, and P2 x P6, P3 x P6, P2 x P7, P3 x P5 and one checks “Prince” (bi>1) and P6 x P9, P1 x P10, P3 x P4, P2 x P10 (bi<1) for T.S.S and P2 x P6 and P1 x P6 (bi>1) and P1 x P10, P7 x P8, P7 x P10 (bi<1) for ascorbic acid. Since these genotypes were indicated to be the most consistent across the environments for the traits mentioned, they can be successfully suggested to use in breeding programs. The study revealed that some reliable predictions regarding genotype and environment interaction, as well as its unpredictable components, played a relevant role in genotype stability. With this aim, the current study can be used to identify more productive genotypes in specific conditions, resulting in a large improvement in fruit productivity.
