Studies on leaf yield and association analysis in underutilized and cultivated Allium species

Abstract

A field experiment was carried out at ICAR-Directorate of Onion and Garlic Research, Rajgurunagar, Pune, Maharashtra during Rabi season of 2017-18 to study the yield attributes of underutilized and cultivated Allium species. All the forty genotypes were laid out in RBD with three replications maintaining a spacing of 25x20 cm. Variation in respect of yield per cutting has been observed. Total yield varied from 0.48 t/ha to 19.80 t/ha. The maximum leaf yield (19.80 t/ha) was obtained in Allium tuberosum kazakhistan All-1587. It was at par with Allium tuberosum CGN-16418(Flowering) (18.20 t/ha), Allium tuberosum Rottl Ex-spr kuchaai CGN-16373 (17.17t/ha) and Allium tuberosum EC-607483 (14.97t/ha). Minimum yield was found in the AlliummacranthumNMK-3216 (0.48t/ha). Correlation analysis manifested total yield had significant and positive correlation with sulphur. Plant height was highly significantly and positively correlated with leaf length, leaf width, and total yield. Number of leaf per plant had significant positive correlation with phenol, flavanoids, and pyruvic acid. Positive and significant correlation between desirable characters is beneficial which helps in simultaneous improvement of both the characters.
