Heterosis Studies for Earliness and Yield Related Traits in Ridge Gourd [Luffa Acutangula (L.) Roxb.]

Heterosis Studies for Earliness and Yield Related Traits in Sponge Gourd [Luffa cylindrica (Roem.) L.]

“…For days to first female flower appearance maximum and significant negative heterosis over better parent was observed in the cross IC-284941 x VRSG-199 (-32.08%) followed by IC-355633 x Patna local (-29.89%) and IC-284941 x Patna local (-28.08%); negative heterosis over standard check was observed in the cross IC-284795 x Patna local (-18.89%) followed by IC-284795 x IC-336759 (-16.42%) and IC-284941 x VRSG-199 (-12.66%). For lower sex ratio maximum and significant negative heterosis over better parent was observed in the cross IC-336759 x Patna local (-52.07) followed by Similar results were reported for the earliness of above mentioned characters by Sonavane et al, (2013), Islam et al, (2012), Sanandia et al, (2008) and Naliyadhara et al, (2007) in sponge gourd; and Muthaiah et al, (2017), Bairwa et al, (2017), Prakash et al, (2014, Narasannavar et al, (2014), Karthik (2014), Lodam et al, (2014, Dodiya et al, (2013) and Singh (2013) in ridge gourd.…”

“…In such crosses expression of heterotic response over better parent and standard check indicates the real superiority of hybrids from the commercial point of view and these hybrids can be commercially exploited after large scale testing. These results are akin to the findings of Muthaiah et al, (2017), Bairwa et al, (2017), Poshiya et al, (2015), Prakash et al, (2014), Narasannavar et al, (2014), Karthik (2014), Lodam et al, (2014, Dodiya et al, (2013) and Singh (2013) have reported high values of heterosis for fruit yield in ridge gourd. Sonavane et al, (2013), Islam et al, (2012), Sanandia et al, (2008) and Naliyadhara et al, (2007) in sponge gourd.…”

Trait Association and Path Analyses for Yield and Its Attributes in Ridge Gourd Commercial Hybrids (Luffa acutangula L.)

“…Its chromosome number is 2n=2x=26. It is also called as angled gourd, angled loofah, Chinese okra, silky gourd and ribbed gourd" [1]. "Gourds are the important vegetables in the human diet especially in India.…”

Assessment of Vegetative Growth Characteristics and Yield of Different Types of Cluster Bearing Ridge Gourd (Luffa acutangula Roxb.)

“…It belong to family Cucurbitaceae with diploid chromosome number (2n =26) and is cross pollinated crop. Ridge gourd is native to India (Muthaiah et al, 2017) and grown throughout…”
