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

Bitter Gourd: Breeding and Genomics

“…Appreciably amount of significant heterosis was reported in desirable direction for days to first female flower appearance, node number of first female flower, average fruit weight, fruit diameter, fruit length, number of fruits per plant, number of primary branches, vine length (Jadhav et al, 2009;Lawande and Patil 1989;Bhatt et al, 2017;Moharana et al, 2018), fruit length and node at which first female flower appeared (Thangmani and Pugalendhi, 2013), vine length, days to first female flowering, fruit length and fruit number (Celine and Sirohi, 1996), number of fruits per plants and days to first harvest (Al-Mamun et al, 2015), number of fruit/plants, days to first harvest, fruit diameter, fruit length, fruit weight, and fruit yield/plant (Pal and Singh, 1946;Singh and Joshi, 1980;Vahab, 1989;Lawande and Patil, 1989). Positive heterosis was observed over superior parent for carotene, vitamin C and total sugar content in bitter gourd (Adarsh et al, 2018). A wide range of variation in the parents and heterosis (mid parent and better parent) observed positive (yield) and negative (earliness) which expressed usefulness of parents in the development of hybrids.…”

Gene Action and Heterosis Studies for Yield and its Attributes in Bitter Gourd (Momordica charantia. L) under Temperate Ecologies

“…Due to the existence of wide variability, monoecious nature, conspicuous and convenient flowers and large number of seeds per fruit, bitter gourd can serve as the most potent material for the exploitation of heterosis on commercial scale (Citation). Various researchers have reported significant heterosis for yield attributes in bitter gourd (Naik, et al, 2020; [7]. But not much commercially high yielding hybrids have been released from public sector organization so far.…”
